WARNING for dog owners: Arthritis Pain Drug "PREVICOX" KILLS.




George my 9 year old rescued Giant Schnauzer is now fighting for his life. He was prescribed Previcox by his vet for his arthritis pains. Following the vet recommendation I administered the tablets with food. After only two days and two tablets he started projectile vomiting, drinking a lot of water, being dizzy and manifesting all the symptoms of poisoning.

I Googled the name of the drug "Previcox" and "side effects" and I wish I would have done it BEFORE giving giving George the drug. To my astonishment, there are hundreds and hundreds of personal testimonies written by people who administered their dogs the same drug, their pets manifested exactly the same symptoms like my George and finally, had their dogs ending up dead or barely escaped death with irreversibly damaged stomachs, liver, kidney or hearts.

From an article published in 2006:

"The FDA has released information concerning non-steroidal anti-inflammatory drugs for pets -- including Metacam, Deramaxx, Previcox and Rimadyl -- that shows they have been connected to 22,000 cases of illness in dogs, almost 3,000 of which were fatal."

What causes death by Previcox? Acording to one of the hundreds of testimonies I found on the Internet written by a dog owner who lost his pet to Previcox poisoning,

"The Previcox apparently starts first by forming ulcers on the stomach and as more Previcox is administered it becomes ulcer upon ulcer until the stomach acids (full of Previcox) begin to leak out. It seams it first attacks the kidneys and liver. Then it begins to destroy all the protective membranes that are protecting all of the other organs. In the end it makes its final attack on the heart."

Read the rest here: http://www.k911.biz/Previcox_Emails/main.php

Previcox is the veterinary version of the Vioxx (prescribed for arthritis in humans) and it is made by Merial which is a branch of Merck. As you may already know, Vioxx was pulled off the market by the FDA after thousands of people ended up dead after taking the drug. Yet, the same company continues to push Previcox which has the same risks and causes deaths in animals.

Before starting your dog on Previcox I beg you: please, if you love your dog go to http://www.k911.biz/Petsafety/PrevicoxEmails.htm and read Rowdy's tragic story as well as other hundreds and hundreds of emails sent by other pet owners who tragically killed their pets by poisoning them with Previcox.

Update at 11:06 PM

George vomited for the third time today and he is very weak, shaking...refused the yogurt but my wife cooked a little beef and carrot soup and gave it to him a few minutes ago, licked the bowl. We expect he will vomit it shortly but that's all we can do until tomorrow morning. We put plastic bags all over the bedroom floor, makes it easier to clean. We'll see what happens until tomorrow when the vet office opens.
I am royally pissed on the vet who did not warned me about the potential side effects and on the company who makes and pushes such a dangerous drug which is banned for humans; if George dies, I'll make taking this drug off the market one of my life goals. I just learned another side effect is extreme aggression (probably caused by pain) and read about a little girl disfigured by a dog who was given Previcox. Dog owners need to know what the risks associated with this drug are. I will start a website and put all the effort and Internet knowledge I am capable of to make it pop on top of every Google search when people are searching the name of this drug.

UPDATED 10-23-2014 (five years after I published this blog entry)
The website that had Rowdy's story as well as hundreds of other testimonials is no longer online. I managed to find some archived internet pages of that website using the Wayback Machine. You can read them here: https://web.archive.org/web/20140701032307/http://www.k911.biz/Previcox_Emails/main.php

How irresponsible of you posting information based on your fears and undocumented stories. Your bad luck with this medicine is just that, your bad luck.

Transsylvania Phoenix said...

You call me irresponsible? The links I posted documenting the FDA report about the deadly side effects of this drug as well as other dog owner horror stories are "fears and undocumented stories"?
Please excuse me for being blunt, but you sir (madam) are a fucking idiot.

My dog Ajax was prescribed this last week. He started acting drunk and couldn't walk or eat just lots of water. Now he has an ulcer that is bleed but don't know if it is purferated yet. Please don't ever give this med to your dog. The Vet does not want to come right out and say this was the cause but I know it was. He was on Rymidol before and was fine but they told me this was better. Please we need this off the market. I still don't know how my best friend will be. My heart hurts.

I am so sorry to hear about the problems you all have had with Previcox. I have a min-pin that ruptured a disk in his back and was in excruciating pain. Our vet prescribed rimadyl which did absolutely nothing - in fact, his pain got worse. It was to the point you couldn't even look at him without him yelping. She then prescribed tramadol and previcox and his pain completely vanished. He was only on it for about 4 days before we were able to get him an appointment for surgery. Without those drugs he would have stayed in excruciating pain. He exhibited none of the symptoms you all are writing about. I suppose we were lucky. Is it possible that the dosages prescribed by your vets are way too high? We were giving our dog half a pill twice a day and like I said, he went from being so painful he couldn't stand up and didn't even want to drink water to being a pain free normal dog and wanted to play all the time - we kept him in strict confinement.

I just finished reading the story about Rowdy and he says that when he called Merck they told him the drug would be out of his system in 8 hours. When we took our dog to the specialist for his back surgery, he told us that it would take 72 hours for the drug to clear his system and he would not do the surgery until then. I trust the specialist over Merck "customer support" any day!

It may be a coincidence, but, our dog took Previcox for a pulled shoulder. Within 2-3 days, he lost his appetite, started vomiting and has been on an IV all week.

It is not a coincidence.
Before prescribing Previcox your vet should have disclosed to you the possible side effects of the drug including the fact that it may kill your pet.
Go to the manufacturer's website and read the drug fact sheet; the paper is expressly warning about these possible side effects and instructs veterinarians to disclose them to the pet owners before prescribing the drug. If something should happen to your dog you should go after the vet for negligence.

I pray for your dog to survive. Mine (barely) did make it and it took him two weeks to pull it through.
Since the Previcox poisoning incident we enjoyed George's company for another 1 1/2 years. Unfortunately last month he was diagnosed with liver cancer. We put him to sleep on Valentine's Day, February 14 of 2011. Here is the blog entry we wrote for him: http://transsylvaniaphoenix.blogspot.com/2011/02/...

Good luck and get well to your pup.

Thank You for alerting me to this poison. I have noticed it does nothing for my dog. I am stopping it today. my question is is there a contraindication with Valium 5mg seems to work much better and what is the correct dose for a 12 y/o 56lb. dog with hip problems. I have been giving her Dasuquin as well with no noticeable change(2 tabs for dogs 60lbs and over).The 5mg Valium seems to work much better.These other meds seem like over priced crap!
Thank You!

I am so, so heartbroken to learn about all the serious problems with the dogs taking Provicox. My large size rescue shepard mix has been on it for the third month, fortunately without any side effects. She could barely get up off the floor and had a miserable time getting around. This drug has done wonders for "Ginger", but I am now wondering how the long term will be. I am definitely going to have a long discussion with my vet. Good luck to all of you who have had problems with it. Again, I am so sorry.

I am so sorry about George. Yes - Prevacox kills - we just had to put out beloved Yellow Lab Willie down because of Prevacox. We had Willie on Zubrin for four years and he did beautifully and than Merial bought out the manufacturers of Zubrin and they just couldn't have Zubrine competing with their Prevacox - the killer drug. Willie was only on it for less than a month and started throwing up - we stopped giving it to him andt ook him right in to our vet were test results showed damage to his liver and kidneys in that short period of time - they tried everything they could to save him but to not avail. Thanks so mucm Merial for killing our dog!! How many more dogs are you goihg to kill with your Prevacox!!

Oh my goodness! My Yellow Lab j(Thor) just turned 12 and has been on Deramaxx for over a year with no side effects. He went from a groaning dog to walking without a limp (within limits to excersise).. Today my vet told my husband it was discontinued because the company mixed the formula with human supplies. He then suggested Previcox. I am a Registered Nurse and look up all meds so I am greatfull for your info. I still have not found a viable option but I am so sorry for your loss and insight. Thank you.

I took my 9 year old bassett hound to the vet on a friday for possible hip problems and might i mention she was overweight at 95 lbs. and the vet said she might have arthritis, but she could get around ok, but not as good as usual thats why we took her to the vet. But to make a long story short, we lost our beloved DAZY to a drug called Previcox. We gave her a pill a day like they told us. First day was ok ,second day was back to her old self, .third day,. she got up ok but after taking Previcox227 the third day she was breathing heavy all day, and pacing the floors and ended up dying with blood coming out of her mouth. We loved our dog very much and always will.So if you love your dog as much as we do ......DON'T EVER GIVE THEM PREVICOX!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

It's such an interesting post on arthritis in dogs. Grayson, a 2 year old male Maine Coon presented with a significant lameness on the left rear leg after falling from the kitchen counter. An xray was inconclusive and a CT scan was performed that revealed a fracture in the growth plate of the left femur in AVDH veterinary hospital. The head of the femur was pinned back into position and he was sent home with cage confinement and medication. At the 1 month recheck, Grayson is back to his old self and his parents are excited with his recovery. Grayson once again loves to jump up on things and cause trouble.

I'm a veterinarian. I encourage all pet owners to look up all drugs given, and do my best to notify of the major side effects at the time of discharge. Look up any drug label and you will see it is impossible to recite every side effect of every drug ever reported.

I do not use Previcox, or Deramaxx. I rarely prescribe this class of drugs (known as NSAIDs) unless my hands are absolutely tied and the pet is in pain and nothing else works.

However, that being said...please try to understand that the same mechanism by which these drugs stop pain is what causes the side effects. It is nothing specific to Previcox or Deramaxx or Rimadyl. These drugs are not "toxic," not made wrong, and not contaminated.

These drugs are like Aspirin for dogs, and almost everyone is aware that aspirin causes bleeding ulcers in humans. They work by inhibiting prostaglandins. Prostaglandins cause pain. Prostaglandins also help keep up the integrity of the lining of the stomach and intestines. When we give these drugs, it does its job by stopping prostaglandins and making the pain go away, but they also stop prostaglandins in the stomach and ulcers can develop as a consequence.

We can't tell the body to only stop making this chemical in the hips or spine, but keep making it in the stomach. That's not how drugs work. It's a risk of the drug, so weighing the benefits vs. the risks and being aware of side effects and early signs of problems is the ONLY thing we can do.

I'd just like to say one more time that I am not defending these products, I rarely ever use them on my patients. I am just trying to turn this emotional discussion into an informed discussion. Please take it upon yourselves to research any drug you put in to your pet's body, and in to your or your children's body for that matter. Always ask your doctor if you have questions. If they are not willing to discuss your concerns with you, move on to a doctor who will.

So sorry for some of the issues people are experiencing with thier pets. I have only had wonderful experiences with previcox for several of my elder dogs. They were all over 50 lbs. This was after exhausting several other products including all natural stuff too. The relief it gave them was incredible. One of my dogs could only walk by having this pill. Again, they were within 1 to 2 years of passing. It took the pain away and they were running around the house and yard again.

The other day, my other dog a small pomeranian was walking funny so I took him to the vet and he showed me how his knee popped out and how to stretch the leg to fix it...meanwhile he put him on a very low dosage..of prevocox..(it was 1/2 a tablet of 57 mg. per day) told me to do it for 2 - 3 days and then I should be able to quit using it. He was right, Casey showed improvement right away and was right back on track. I don't know, maybe the dogs were given too much for thier bodies and it worked against them. For me it has been so helpful...also, the people I have sent to my vet for this for thier pets have also raved about the results. Not every products is best for everyone.. So sorry for the bad experiences I truly know the heart break of a sick pet.. I have between 5 - 8 pets in my home most of my life! Hope this helps someon

I wish I have read way before. My German Shepard female dog has been on prIvicox. She started to have seizures. She is ok but seeing her in pain just kills me. I am stopping this med today and calling the Vet. Tomorrow for not telling the side effects. This medicine is not the cheapiest . I love my dog and I will anything to save her. Thank you everyone for post your painful experiences but it may give a chance for my dog to live. God bless you.

Our 12 year old cocker had surgery in December. Was prescribed Previcox for post-surgery pain. I only gave it to her two nights as I am very leery of drugs. Since that time, she has been eating less and less no matter what we offer her. Very lethargic - doesn't even want to go for walks. Staggers a lot. Today she only had two bites of food and rejected the rest. Have not notices excessive intake of water, and no vomiting, but lots of diarrhea. Could she be suffering from side effects of previcox? We are now wondering if we should have her put down. We just don't know what to do. She is skin and bones. It is terribly sad to see her.

I have a 10-year-old Brussels Griffon who has been on Previcox for some time with severe arthritis in one leg. The last three days I have noticed no appetite and then started vomiting mucous-like vomit with specks of blood and black, tarry stools (which is a very high sign of blood). He is wobbly and very lethargic. I am cooking him brown rice with chicken right now to see if he will eat something. My sister is a vet tech and she said that Rimadyl and Previcox has those side effects. I am beside myself watching this little guy the way he is. Checking with the vet in the morning. Praying for all of you with pets suffering from the same side effects.

Guud luck with your pup. It is very important to replace the liquids he is losing and keep him hydrated so buy liquid electrolytes from the drug store and force him to drink (use a teaspoon or a syringe.

SJH said...

Our Golden Retreiver Cheech - 12 years, took Previcox for 3 months - and we thought he was just declining with age, until he stopped eating. Monday April 15, 2013 we took him to the vet first thing - he was in Renal Failure, and since his prior bloodwork was normal, the Vet realized it was the Previcox that poisoned him. He has been getting fluids all week - and Thursday 4/18/13 it looked like we would have him back today. Then he had for the first time in his life a Grand Mal Seizure late yesterday, and he has been in a coma since. By the way Merial (Previcox) is paying all our vet bills - doesn't help our boy one bit - but at least once less burden. The Vet said we will probably have to put him to sleep this afternoon - 4/19/13 - because he hasn't woken and has had 2 more seizures - NOT a happy pet owner!!!
Our poor old boy - he didn't deserve this - at all!!!

My dog just died from prevacox.
It feels like somebody literally tore my heart out. I only gave her one pill then stupidly googled the drug afterwards. She went downhill quickly and yes it did burn holes in her stomach. I am left with 6000 dollars in vet bills and I had to watch the love of my life die a horrible death.

My dog Tango too died from Previcox after being prescribed for what the doctor said was arthitis. She did not do a blood test to my knowledge nor did she take xrays to confirm the arthritis diagnosis. Twice i went back to the vet to ask for a different medication as he seemed to be lethargic. Twice they would not give me anything else but told me to give 1/2 the dosage and that it would take time to get better. 4 days later he died from a ruptured spleen/internal bleeding. How many dogs have to suffer before this is taken off the market? Is there a class action suit? I am interested.

This drug was given to my 3 month old boxer puppy in February 2011 after his neuter surgery to prevent his pain, since he was cryptorchid and had 3 incisions. My boy is now going on 3 years old this October, and while he didn't have any obvious side effects, i am concerned he took this drug to begin with. As i see it's usually prescribed to dogs with joint issues like arthritis. And I'm also worried if it's the cause of him having a sensitive stomach, and having the occasional vomiting spell every few months. Interesting info to come across. I'm sorry for every ones loss of their beloved pets due to this medication :(

My 12-year-old Pomeranian was recently diagnosed with acute arthritis and was prescribed Previcox. He has not experienced any adverse reactions,but has seemed to get around much better. However, reading the horror stories on this page has prompted me to search for a natural alternative. There are several holistic alternatives available. Acupuncture it's one, but it can be costly. Supplements are also available, such as glucosamine chondroitin and sources of Omega 3 to reduce inflammation and lubricate joints. With a bit of homework one will be able to find a suitable alternative remedy for your dog and your wallet.

Stay away from Provicox! My chihuahua dislocated her hip. Prior to scheduling any surgery, my doctor told me to give her Provicox. My dog was still normal except for her legs. The a few day days after she stop eating...a dog with great appetite...then she started vomiting excessively and diarrhea with black stool meaning blood in her stool. After 4 days of not getting her to eat I took her to the emergency vet. Besides the dislocated hip, now she has pancreatitis., users in her stomach.which could kill the dog. The doctor told us not to use Provicox anymore cause it does cause major stomach problem lik pancreatic. A few thousand dollars after. My dog is still trying to recover from this and we need to get her healthy before any leg surgery can be done which is the original problem we started with. My poor chihuahua has gone to so much because of this medication and she not out of the wood yet. Please don't use this drugs on your pet.. I'm hoping my dog makes it through this. Bonita's owner.

Monette B said...

Provicox just killed my healthy dog two days ago. I brought her in for a dislocated hip that was 100% fixable .Then Provicox was prescribed and a couple of days after my dog started vomiting and having diarrhea and lost of appetite. My poor chihuahua suffered so much on this than from her leg pain. We end up in emergency Veterinary hospital where an internal it's specialist had to do an ultrasound and found ulcers that lead to pancreases. The vomiting lead to fluid in her lungs and hard of breathing which then they had to incubate her to give her much needed oxygen. All this suffering let to a cardiac arrest that killed my dog in two weeks. $6000 layer, what started as a leg problem end up to the death of my dog. It's not the money but the suffering my dog had to go through. A Veterinarian internals specialist from the emergency hospital that told us that Provicox causes ulcers and pancreases and not this site. If you love your pet and don't believe what others have shared here then believe an internal specialist. I have lost my loving dog. There is nothing I can do to get her back but I just want to prevent anyone else from losing their beloved pet.

My 3 year old mix lab /Shepard has two bad back legs. The vet said we would have to put him down. He was growling when we petted him and couldn't go down stairs, had to walk w front legs only. We tried rx but it made him sick. So we found an all natural supplement that is vet tested with scientific studies that naturally reduces inflammation. After a few weeks he was going up and down stairs again (thank goodness that's how he goes to the restroom), stopped growling (from pain) and the yellow in his eyes is gone. Better energy and not anxious anymore .. Just happy. No side effects since its all natural it won't tear up his stomach or have toxic side effects. We are so thankful bc we were close to putting him down and he's my kids buddy. If you want the order link, send me your email. Many happy days in the park! Manymissions@gmail.com

I have just read all the things people have said about this medication and just don't know what to do. My german shepherd female of seven years was diagnosed with CDRM about five months ago and given four to live! This was a shock in itself. Then the course of the illness has not gone as expected and saw another vet who said she could have spinal degeneration/arthritis and prescribed this dreaded drug. She already cannot tolerate metacam so this is likely to kill her! She is due xrays etc on Friday so am not going to give her another one of these pills. Could someone from the UK give me some advice about where to get more natural ways of dealing with this. She is seeing a vet for acupuncture. She seems ok at the moment but cannot take this risk and like CDRM it all needs more awareness. Thanks for reading this

My little Yorkie is also going to lose his life because of this drug. We were told he had arthritis and was prescribed Previcox. He took it less then 2 weeks when he stopped eating and drinking, was vomiting with bloody stools. Took him to the vet they did an ultrasound and was told he had kidney and liver damage along with pancrititis. after paying thousand of dollars trying to save his life I was told he is not going to make it and that he should be put to sleep. As far as I'm concerned that vet that gave him that medicine killed him. Something has to be done to get this off the market!!

disgusted. said...

Well, my worse nightmare is coming true. The vet wants to put my dog to sleep. Two weeks ago he was brought to the vet for his shots and I was told he was healthy. The prescribed him Previcox for arthritis. After a few days of giving him this drug I thought it was helping him but little did I know it was poisoning him. Only after a few days he ended up at the vet hospital with liver & kidney damage, an ulcer, pancritis and a heart murmur. After thousands of dollars spent they decided we should put him to sleep. When he was admitted they brought up this med to me saying it could be the cause (which is how it was brought to my attention) but after a while they said it was antifreeze which I know was a lie as my dogs only go outside with us and are on a leash and our cars are always in a garage. I didn't even have a driveway till a week ago. I know this drug poisoned my dog and I think every animal owner should be aware of it. I found a website where tons of people gave this drug to their dog and their dogs suffered the exact symptons as mine and died. I am heart broken and feel so bad seeing we gave him this drug trusting the Bolton Veternarian. It needs to be stoppes so no one else will have to deal with this heartache. If they use to give this drug to humans but banned it because it was causing death so why are they still giving it to animals? This drug has to be stopped and I am going to do whatever I have to to get the word out so no more dogs will die.

Really sorry for your pet. I would recommend you to get a second opinion from another vet before putting him to sleep. It may cost a little bit of extra money but you will be at peace knowing you did all you could do for him.
As for the killer drug Previcox: spread the word on Facebook, Twitter and your own blog (if you have one). Talk with your relatives, friends and other dog owners whenever you meet them. People need to know about this poison prescribed as a "cure"

Thank you for your kind words. I refused to put my dog to sleep and went to Fox news in Connecticut. A reporter came over my house and we did an interview about the drug and they aired it. After that the vet hospital kept treating my Yorkie Benji and he is improving every day!! He is eating a little and drinking on his own. His counts are down and it looks good. He's still not hisself but hopefully he will come home soon. I called the manufacturers about this drug and put in a case with them. Hopefully they pay the vet bill. I also talked to a lawyer about getting this drug off the market. I am spreading the word everywhere I go. I even made a facebook page and people are joining. Since my interview was aired I am getting emails and letters in the mail from people who lost their pets to this horrible drug. Thanks to you for without this page I would never of known how bad it is.

That is really great news, your dog pulling it through is nothing short of a miracle.
I would really appreciate if you could send me a link to the TV aired segment on Previcox and if possible your Facebook comments page.

I am absolutely sickened reading this. Today is my 2nd day (and will be the last day) to give my dog Previcox. I wish I would have read this two days ago. I trust the vet is giving her what she needs. I will be calling him in the morning to discuss. I am so sorry for all of your losses. I cannot bear the thought of losing my baby, Onyx, and pray that no damage has been done. Hopefully your posts are saving lives.

My 15 year old dog has been on Previcox for one month as a treatment for her osteoarthritis. She was a very healthy and energetic dog for her age, but has since been off her food, lost weight, has trouble walking and standing. Her eyes look vacant. I thought that the end was near.

The vet took tests of her liver before prescribing Previcox and said that she was not in danger. No other side effects were discussed. I'm so very thankful I found this and other sites that document the adverse and sometimes fatal side effects.

I am taking my dog off Previcox and calling the vet tomorrow morning.

My heart goes out to the dogs and their humans who have suffered because of Previcox.

Here is the info you asked for. Update on my little Yorkie Benji. He was in the hospital for 16 days as I refused to put him down. Tjey told me only a miracle would save him. Well I prayed everyday and my husband and I were at the vet 3 to 4 times a day everday loving him and trying to get him to respond. The night before they were going to put a feeding tube in his neck I went there and kept rubbing the gravy from the food trying to get him to eat. He would lick it but kept snubbing the food and not drinking water either. The next morning the vet called me and said "Benji Ate" You can imagine how happy I was. Everyday got better & better and after 16 days of fighting for his life my little guy is home and happy. He is eating like a trooper and is finally starting to drink water. My vet bill is almost 1700.00 And the manufacturer of the pill is paying 5000.00 of it. The vet that gave him the pill is not the vet who saved his life but they are from the same hospital. She is a very young doctor and is wonderful. She never gave up on him even after the specialist and everyone else was throwing in the towel. I asked her to please save his life and she did! He will always be on a special diet now and probably be on meds the rest of his life. He has high blood pressure now so he is on meds for that too. But I love him and do what ever it takes to give him a good life. Still this drug is being given out to other animals.

disgusted. said...

Please everyone, If your told to put your dog to sleep a few days after giving him this drug, REFUSE! It takes at least 2 weeks of treatmentand love to bring your dog back around. I refused to put Benji to sleep and went to the hospital 3 to 4 times a day to love and cuddle him and try to entice him to eat. It was a struggle for all of us especially my little Benji but he is a fighter and I prayed everyday. God heard my prayers and saw how hard Benji was fighting for his life so he saved him. The vet told me many people will give up after a few days and have their dog put to sleep. Don't do it!! Refuse and make then treat your dog as long as you can and call the manufacturer to put in a case so they will pay the bill. Don't ever give up. Only you can save him/her. The vet said she couldn't believe how dedicated me and my husband are with Benji. He became their star miracle dog and now when he goes for his weekly checkup he thinks he owns the place! The girls love him. Anyway the reason for this post is to tell you all not to give up. This drug is poisoning dogs and they are not going to get better in a few days. And during his/her hospital stay be there as much as you can. Love helps!! Please spread the word about this horrific drug and join my Facebook page on this drug and share it with everyone.

That's a truly inspiring story, thank you for sharing.
Our George made it too, but barely. We nursed him back to health at home and it took him almost two weeks until he started drinking then eating on his own. It was an epic struggle considering how big he was - 120 lb on the scale. He lived another two years after this episode and finally passed away after being diagnosed with pancreas and liver cancer.

I'm so so sorry about sweet George. I'm happy you had him for a couple of more years before the Lord took him to heaven. I know Benji's life span will be cut short because of this drug but I will cherish everyday extra I have with him. Remember love never dies and George will always love you and his spirit is always with you. They love us so unconditionally. What love is better then that? Just know someday we will be with our little ones again.
Thanks to you and George Benji's life was spared. It wasn't easy but I just couldn't give up on him. Many many thanks!!

Your story about George made me cry. You were his hero and he was yours. You were lucky to have each other. It was in God's plans for you two to share your lives together. I'm sure George is happy in heaven waiting patiently to see you again. God Bless you both.

I live In England . My Lhasa has been on Previcox for 3 years now without any problems. She could barely walk and was in considerable pain before my vet prescribed these tablets.
All medication human or animal have side effects, and some more than others can have a bad reaction, or sadly even death.
I am just stating my view on giving this medication to my dog, and I do make sure she sees the vet every 3 months, when she is due for repeat meds. I thick all pet owners should discuss any type of medication with their vet before agreeing to give ant to their beloved pets

9/2012 My Jasmine was havieng some really bad issues, later diagnosed as colitis. Previcox 227 was one of the meds she was prescribed. QTY was only 3. This date 11-4-2013 while checking left over meds I found 2 that were never given to her Reading this about others who have had it prescribed for their pets and lost them due to this med my intention is to destroy. I other meds that have no longer been given to my Jasmine, which I just found and am looking them up. Thank you for the education on this. Jasmine is only 6 and I intend on having her around and healthy another 8 years or better if that's possible. God Bless all of you who have suffered the loss of a beloved furkid.

My blue heeler was hit by a car last week and had her leg broken. It was splinted up Friday and I gave her half a 227 mg Previcox on Saturday morning and by that evening she began having diarrhea. I gave her another on Sunday morning and her diarrhea became severe and she began vomiting, drinking huge amounts of water and was somewhat non responsive and lethargic. I began to suspect an adverse reaction to her medication and this was one of the first sites I came across that had pertinent information. I did not give her another dose and after two days of detox and some Pepto Bismol she got over it.

Thank you for posting this, I believe you helped save my dog's life.

I have a Black Lad that is 14, He was having trouble getting up because of bad hips. Took him into the doc and was given Previcox. He was on it three month and started getting sick and would not eat, took him back to the doc and the doc. did blood work and said he would only make it two more weeks. My lab would not take his pill any more, but at first did him wonders. He has not had the Previcox for over a month now and has taken a lot of work and feeding him lots of potatoes, rice and meats, but is now gaining weight and doing a lot better now he is off the Previcox. His doc. now will not prescribe this drug again. At least we now have a few Doc. that will not prescribe anymore.

Hi, I live in Ireland and my gorgeous 12 year old dog died last week secondary to previcox. Started on previcox on the 25/10/13 for arthritis and died on the 14/11/13. I stopped the drug on the 7/011/13. Like the other stories he was great first week up and active but then noticed he was off food off form and appeared to be nauseous ( retching occasionally which I misread for days ). However as he was always such a loyal dog and eager to please I really didn't realise how sick he was until I found a small lesion on his back. Vets dismissed my concern cover previcox completely. On exam he has an enormously elevated white cell count which is in response to some massive inflammation/ infection had lost almost 3 kg since commencing on the drug . On the third day at the veterinary hospital he began to bleed from his mouth ,nose and cannula site . He had what is known as disseminated intravascular coagulation(DIC) so we had to euthanize him . Vets continued to dismiss my concerns relating to previcox despite not really giving me an reasonable answer for his death. Only way to prove it would have been an autopsy and felt kids wouldn't have been able to deal with that situation. Dog was also on the higher dose of 227 mg when manufactures recommend 5 mg per kg. he was 25 kgs. I feel I really let my dog down by not familiarising myself with this drug prior to him commencing it. I had recently taking in two rescue kittens and I misread his withdrawal as anxiety about the kittens - he could be anxious at times ! His buddy of 11 years is lost without him , keeps wandering around house and garden looking for him ! I have no doubt that previcox killed my dog and after several discussions with vet he has agreed to report it to medicines board .

Our Cavalier Molle just died after eating Previcox for his stiff back for three days, vomited blood in the morning and we went quickly back to the vet. Where he was treated for two days but after receiving pancreatic inflammation and fluid in the lungs after his own vomit, it became too much for our little fighter.
Miss you Molle!

Hello, I'm french, so excsuez me if what I write is not very understandable .. I use the Google translator.


My dog Nono English Bullterrier of 12 years died the 15/12/2013 has cause of the previcox.

I shall like knowing what treatment(processing) has make has my dog, it me work many. I know that it is the previcox which to kill her(it) but which damages that made has my nono? I saw him(it) suffering but that it is him(it) crossed(spent)?

I take him(it) to the veterinarian for the evil on one of this back leg, the degenerative osteoarthritis or damaged ligament, injection morphine+metacam, nono reacted apparently well, puts its leg and walking(step) has little ready good.

The veterinarian prescribes him(her) 1 stamp(tablet) PREVICOX 227Mg for 10 days.

2eme in the daytime of grip(taking), my nono is weakened but suffers not many of its leg, I am relieve but it is tired, eats little and drinks little while usually he drinks a lot.

3eme in the daytime of grip(taking), he(it) does not eat and does not drink not at all, make small liquid saddles, gets up and walks(works) but remains on-the-spot during times(weathers) to asser surprising as has to think and rests(bases) at the end of about meters, tired and has for girls tou, I begin has to worry me.

4eme in the daytime, he(it) coughs a lot, trembles, vomited, gets up no more, pants, na anything drunk or to eat for 2 days, I watch over it all evening long, I think in of urgency, hesitate (very too much), tired I fall asleep, 2 barking wake up in the early hours, I rush to see my dog he(it) is in the lounge(show) grow longer on the highly-rated, the mouth enters opened, the language(tongue) which moves and the fixed look, me does not include and speaks to him(her) in the affectionate, it does not react, it does not breathe any more, my dog is dead man ., be 4 has 5 days after the grip(taking) PREVICOX

Previcox can certainly relieve pains of your dog but he can also kill him(it) in the suffering.

My kind and gentle constant companion of 14 years was put to sleep on 12/23/13. Prior to her bloody vomiting and having no appetite, she had taken Previcox. 57 mg. I gave her quite a few. In the end, the kidney damage was so extensive and severe, there was nothing left to do but end her misery. I'll miss her forever and I'm sorry for the pain she had to endure because of this.

what is wrong with you people??, previcox must be given along metronidazole, in order to prevent all the side efects most of you mention, like ulcers!! i've been giving both drugs to my 10 year old dog, for 3 days now and she's doing just great!!

Transsylvania Phoenix said...

What's wrong with us people?
Maybe you should ask what's wrong with the manufacturer who is marketing this drug and is not asking veterinarians to disclose the deadly side effects or at least prescribe another drug to minimize the risk of ulcers and liver damage.
Not every pet owner is also a part-time vet. Expecting people to know this kind stuff beforehand is unrealistic.

Anonymous said...

While I appreciate YOUR experience with this "bad drug"; you certainly put me into a panic with our little girl who was prescribed this for an injured paw yesterday. Just an FYI: ANY drug can "kill". Have you watched TV lately and seen how drug commercials with their happy smiling faces are also filled with voiceovers of how a drug that will help you with your depression could ALSO cause "death, kidney failure and 10 other bad things"?

I called my vet and asked her for HER experiences with this drug and she felt confident with the factors with MY pet, that prescribing it was the right thing. You don't seem to take into account that the factors with YOUR pet may have caused his illness (and trust me...my pets are my CHILDREN. you do NOT wanna mess with me with my kids!), or that your vet who prescribed it did not perform blood samples ahead of time (depending on the age of the pet, that is a HUGE factor).

There is someone local to me here who is on Craigslist with REPEATED posts, claiming a local vet (not mine) is "killing animals" and needs to be "put out of business", and this is what your Previcox post reminds me of. Your experience means this drug KILLS. After all, you succeeded in making your headline pop up in my google search. I am not so sure that is a responsible way to make your case, as someone as stated. Plus, I did not see ANY follow up on this whole thing...and that "inexplicable reason" for 25 other comments not showing up seems...weird...at best.

There are over 100 comments only on this blog post from pet owners who lost their dogs to Previcox adverse reactions. If that is still not enough for you, see here: http://www.k911.biz/Previcox_Emails/main.php
Good luck with yours. I truly hope you won't come back crying and saying "I wish I would have listened to you all"

I see that all posts must be approved by Transsylvania Phoenix so if this comment posts then the author will allow opposing opinions to be heard.
I am a veterinarian and have been working with dogs for 27 years. Before the availibity of the newer NSAID medications (specifically Deramaxx and Previcoxx) I would have very limited treatments for dogs with severe osteoarthritis or acute joint inflammation. These medications are very valuable in treating inflammation as well as improving geriatric dogs "quality of life" to the point that I feel that many of my patients have lived 6-12 months beyond where they might have been euthanized for immobility or suffering. With that said I have a few basic guidelines that I advise my clients on the use of these drugs:

1. Never ever use aspirin!!! aspirin stays in a dogs' tissues for 5-7 days, if a dog has been given aspirin and takes deramaxx or previcox, then you risk severe GI ulceration. Some OTC even "natural" remedies contain aspirin or other NSAIDS that can put your pet at risk. Other NSAIDS that are toxic to dogs include ibuprophen and naproxen. Do not use anything unless cleared by your vet.
2. Do not use any other NSAIDs along with Deramaxx or previcox. Other commonly prescribed meds include rimadyl, meticam, and etodolac. Ask your vet about appropriate "washout times" between giving one NSAID and another.
3. If you can afford it, have a blood panel done before and 2 weeks after starting these meds. Then regular 4-12 month screenings. I strongly recommend, but don't require these tests as long as pet owners follow my recommendations.
4. Use the lowest dose that works. Most dogs respond to half manufacturers recommended dose and some will be fine with a quarter dose. You can also adjust the interval from 24 to 36 or 48 hours "As needed". You should be able to tell if your dose is working by observing an improvement in limping or stiffness. If you see no improvement even with a "full" dose, then you might not need this medication, or something else may be going on.
5. Give your dog a "washout day" after 4 or 5 days on the medication. A washout day is a day where you skip his NSAID. This allows your pet to metabolize all the NSAID in his system and start the next dose the following day with essentially "zero" NSAIDS in his system.
6. Never give your dog an NSAID if he may be dehydrated. Most liver or kidney toxicities have occurred when a dehydrated dog is medicated. I had a patient that had a toxic dose after the owner gave him Deramaxx following heat stroke. Be sure your dog is eating and drinking and not vomiting or sick when you give him his arthritis medicine.
7. Try other evidence based, proven arthritis treatments. "Multimodal" arthritis treatments include nutritional supliments: glucosamine, chondroitin, and omega 3 fatty acid suplimentation along with NSAIDs and Adequan injections. Obesity managment is critical.

With all this said occasionally "Shit Happens", occasionally a patient will have a severe toxic reaction to a drug when 99.99% of other patients will be fine. I am saddened that some beloved family pets have been harmed by this medication, however I feel its a very beneficial drug if used with a little common sense.

Hi just read everything on your post about f… Previcox, our boy Alfred a healthy 10 year old English Mastiff died on Saturday having been given this drug.

I am 100% sure it is this that killed him, all he had was a swollen elbow, xray said arthritis they gave him Previcox without a word to us that it could harm him nothing at all, and we stupidly done it 2 days later he was in a state black poo, vomiting this horrendous stuff up looked like the lining of his gut, heart rate up panting sort of out of it, we had to have him put to sleep, after the vet came out ran more blood, and said kidney failure, this boy had nothing wrong with him except a swollen elbow that he showed no sign of before last Tuesday its been quick, and a huge loss for us.

Just thought I should share, we are English but live in France, I don’t know if there is anywhere I can take this but let’s put it this way I am angry as hell

Alfred was a rescue and had a crap life before he came to us he was failed by humans and now failed again by humans that manufacture and prescribed this drug

Posted a comment on February 24,2014 about my beautiful lab. Took him to the vet and the vet said he as numerous issues and doesn't know where to start. He is at home at the moment and not on previcox.Previcox has taken the life out of my beautiful boy. This drug that is suppose to be wonderful has only given my boy harm. He is a completely different dog and I know there is underlying issues that we are waiting to hear from the vet. How can a dog become life less and can hardly stand up. I beg anyone not to give this drug to your pet, it is a toxic drug and should be taken off the market. I believe vets have a responsibility prescribing this drug. Looking at my beautiful lab at the moment, he is trying to stand up and his legs are giving away. I feel quite sick that I have given him this drug and I was misinformed how serious the side affects can be and was unaware that it can cause death. If I had known this I would not have given this to my beautful lab max.

Tammy said...

My dog was also prescribed Previcox ...today. He had one dose, and he's had two severe seizures in the past two hours. He will not be taking anymore of this medication. I would sooner see him limp from arthritis or carry him around than watch him go through that again. Veterinarians should at least warn you of this if they are prescribing it. It's apparently a fairly common side effect from what I've been reading online.

My poor 12 year old boy, Roscoe, has been on Previcox 227mg now for 5 years for arthritis and I am so shocked to read these reviews, he has gone down hill in the last 6 months, started panting and wretching, we took him to the vet and after x-rays vet said he had a collapsed trachea, he is getting unresponsive, staggering, panting, difficulty getting up and drinking loads of water, after reading these reviews my boy will not be getting anymore Previcox, just at the weekend I got him some glucosamine + chondroitin tablets from the health shop, hopefully these will help and I get to keep him for a while longer.

Transsylvania Phoenix said...

If your dog has been on Previcox for such a long time and didn't manifested adverse effects, it is highly unlikely he will start having problems in the future.
Symptoms of Previcox poisoning usually start within 24-48 hours after administering the first doses. You are one of the lucky dog owners who will never have to deal with other people had to gone through with their dogs. My advice is since in your dog's case there are no side effects do not stop administering the drug.

Thanks for the reply, sorry for showing some ignorance about the Previcox poisoning, thought it would still be best to take him off it and try him on the natural remedies such as the glucosamine powder.

My dog was on NSAID for several years without complications. She developed the same symptoms that yours did. Fortunately. I have an extremely knowledgeable vet, and she was immediately diagnosed with Myasthenia Gravis, and started treatment immediately. This disease is extremely rare in canines, and there is only one vet who is able to test for it. She is located at UC Davis, where she conducts research on rare disorders.

After she was diagnosed, I did a great deal of research and found information possibly linking NSAIDs to Myasthenia Gravis. Of course, it is not evidence based, but I thought you should be aware. Given this disease is so rare, it is often left undiagnosed. Most vets never see a case throughout their whole career.

Our beautiful,loving,gentle Hungarian Viszla has just been diagnosed with prostrate cancer.He is only 5yrs 9mths old. I cannot imagine life without him.
We saw an oncologist yesterday and the is not able to have surgery or radiotherapy because of where it is. He had his first chemotherapy yesterday and has been taken off metacalm and given Previcox 227mg.
After reading these comments I do not know what to do. The worrying thing is that he was given Previcox before his diagnosis and in a routine blood test it was picked up he had inflammation of the pancrease. I wondered where this had come from.
I will be contacting the vet again immediately before he starts asking them again .

My dog has been on previcox for 2 days, she is usually very outgoing and confident, she is now hiding in a corner and shaking, she is hunched as though she has abdominal pain. I am not giving her any more doses, but is this likely to be the cause of her behaviour? I am very worried about her.

I took my 13 year old beagle Oreo to the vet last Thursday because she woke up with a limp. They checked her and said it was probably arthritis. Like I said she is 13 and she is a bit overweight. They gave me a bottle of Previcox and some joint supplements. I stupidly gave her one of the Previcox as soon as we got home because I didn't want her to be in pain. Later on I started to read about the Previcox and came across your story and many others. I decided not to give her any more. She has only eaten twice since Friday, she is not drinking much water, she lays in the same spot almost all day, and today she has black tarry stools. I feel so awful. I always read up on medications for everyone in the house because I got drug induced lupus from a blood pressure medication so I stay away from pharmaceuticals now. I don't know why I gave her that stupid pill before I read up on it. The vet didn't say anything about possible side effects. I did some reading and I gave her some aloe vera juice with slippery elm, licorice root, alfalfa, ginger root and a couple of other herbs. They are supposed to help soothe the stomach lining and hopefully help her heal. I will let you know if it works so others can try it.

Hi ,sorry to hear about everyone's loss of a loved one. I'm from Australia , we had also been prescribed Previcox 227. Had i known about this drug earlier , my beautiful 9 yr old malamute would still be alive . She died from the 2nd dose.

I am blaming myself now for not being cautious about the drug ,i google everything out of paranoia. But I did not think twice when my trusted vet gave her this drug
Yes i blame myself and yes i should have asked more questions , but at that time , she was immobile and something had to be done , she did get an injection that was very effective, but was also prescribed this drug... from a trusted accredited Vet ,who was her treating Vet from when she was a pup.But he had not disclosed any information apart from the dosage instructions , 1 per day with meal. I don't condemn him for prescribing this , he might have successfully treated others , and they turned out alright , but now that i see there are so many cases of pets dieing , I dont want anyone else to make the same mistake.

I ask permission to post link or part of this blog to my facebook page, 'Indie Bear' in memory of her . I have emailed RSPCA and I am in transition of communicating with the Agricultural welfare dept of our government .I'm not sure if my efforts will be effective, since this has been a problem for a while , and would have been banned immediately if people had an open case about it.I am angry that this has happened so I want people to be more aware of this drug . As i said earlier , had i known about this and your blog, my beautiful girl would still be alive.

When will they take this deadly drug off the market? My beautiful sweet Samoyed was given this by mt. Vet for a slight fever. She was only 2 and had no arthritis issues at all!! We didn't give her all the pills. Thank god. She was in the ICU for 3 days and should have died at 2. I thought we were over this. My dog got extra skeletal oestesarcoma 4 years later at age 5 1/2 almost 6. This is bone cancer in her liver. This is the same organ that was hit at age 2 with previcox killing 40 percent of her liver. Vets will only tell me that this cancer is extremely rare ( even rarer starting in the liver). I know it was this previcox that did it. Most dogs die from a severe reaction. I guess mine lasted 4 more years. She only lasted 27 days after being diagnosed with this bone cancer growing in her liver! We tried surgery and Chemotherapy. The tumors kept growing in her liver and then to her lungs. No cancer in her breed line. Previcox should be taken off the market and the Vet should never have given this to her for a slight fever and should be out of business. My beautiful Aspen should't have had to suffer like this! She wasn't even 6 years old.

I, to can add my horror story along with so many, I lost my boxer Tia in the same way. By the time I picked up on what was happening it was to late. I found out May 26 Tia had Mass Cell Tumor, the vet gave her 6 months to 1 year max. But thanks to that disgusting pill (Previcox) she only made it 1 month and 4 days. My vet told me the same thing the pill is very good. I know I will never give any medication before I check for side effects. I also read Rowdys story and could relate to everything he said. We have to get this drug stopped before any other animals become another statistic. To me the love I had for Tia is so much more than a statistic. I feel so responsible for this out come, I can barely stay in the same room with myself. She trusted that I (her mommy) would protect her as she had protected me, Previcox I hate you.

I started giving my older dog previcox due to age related aches and pains. 5 days later I notice that he's ataxic, wobbling when he moved. I thought it was because as he's aged his old cervical spine surgery was coming back to haunt him. I started getting suspicious it might be the drug. After reading your blog, I know it is the drug and he will never get it again. I only pray that he will be okay. This dog is the love of my life and if he dies I will never be the same.

My Dobie has a limp, think it is a sprain from rough playing with another dog. The Vet gave her 10 Previcoxx 227 Mg tablets yesterday. I gave her one when we got home but after reading all these stories don't intend to give her any more. She drank a ton of water at mid day today, she wasn't hot or anything, just started drinking and I though she would never stop. Now, I am very worried

Thank goodness someone has a site warning dogs and their owners about this drug. The Vets ARE NOT monitoring this drug after prescribing it. My beautiful Samoyed was given this by my vet fro a slight fever at the age of 1 1/2. She almost died from it. She spent 3 days in the ICU and watold that it was a miracle she survived. She had major liver failure. Then 4 years later she developed bone cancer in her liver. The same organ that was attacked by this drug. She lasted 27 days and died at the age of 5 1/2. IT WAS THIS DRUG THAT KILLED HER! Vets don't want to hurt working with this large drug company. It may help some dogs. However, they give you a case number when your dog gets ill. WHAT DOES THAT TELL YOU. Please beware and monitor your dog after being given this drug. Shame on Merial for not telling the truth about how many dogs have died or become seriously ill from this drug. They just want to sell their drugs. Vets should be warning dog owners too. They are NOT! Please beware.....

Sorry Guys, but my GSD has been taking this for some time and it suits her well. She has got some quality of life back, entirely thanks to this drug. All drugs have side effects - even common aspirin. You just need to be aware of them and react accordingly. Always read the advice note in the packet BEFORE administering the drug. If you don't, you have only yourself to blame if you miss warning signs.

Our Border Collie (8 yrs) has had Previcox (227 mg) for over two years now following an accident that resulted in major surgery to both back legs (plating (fracture)). I have to say the drug has been the making of her, she now enjoys an active life and is happy and appears to be pain free. Just like humans one medication does not suit all.

I've heard of vomiting being a sign of pain in dogs. My dog had kidney stones once, and he vomited all the time and we never could figure out why until we took him to the doctor. I guess it could be a sign of arthritis too.

None of the links you provided are working. I had a Great Dane die from IMHA (immune mediated hemolytic anemia) because of Previcox. There used to be a site with a bunch of reports of very similar IMHA deaths after dogs were given this drug, but I can't seem to find it. Please email me at pupsavr4life@cox.net if you know of a working site that has gathered all of the deaths related to Previcox.

My mixed breed (10yo) has been on Previcox 227mg at the rate of 1/2 tablet a day for the past 4 months. Have just purchased a further 3 months worth of tablets, (very expensive). No noticeable side effects so far and his condition (badly degraded front left elbow and associated limp) has improved. I am going to change his dosage to 1/2 tablet every other day - to see how little of this drug I can administer and still keep the pain at bay. My vet did recommend ongoing monitoring (blood tests) a couple of times a year to ensure all organ function normal. The experiences of some people using this drug is making me more alert to the possibility of problems long term tho, so I am going to the vet this week for a baseline check up for my dog and a discussion of this blog content.
