Stories of Users of Rimadyl 
11/10/03 Administrator

"Within a couple of days of starting Rimadyl, Biff perked up and was moving freely. We were optimistic. However, within approximately 10 days, he started vomiting large quantities of blood. Alarmed, we took him immediately to the vet. The vet felt there was a pre-existing condition that was complicated by the effects of old age. We took Biff home and, within a month, he became lethargic, could not stand, became incontinent and could no longer eat or drink. Biff, who was just one, big, goofy Lab with a heart of pure gold looked so sad and as if he was in a great deal of pain. His condition deteriorated so quickly, we were at a loss as to what to do. Our vet could offer us no hope. We finally decided to have the vet come to our house and put him down. 

The guilt I feel is tremendous. I wish I had known that vomiting blood was the 'classic' initial symptom of a reaction to Rimadyl. I wish I had known there was a possible 'treatment' for a reaction. I cannot believe that Pfizer can continue to dispense this medication. This just should not have happened. Other than the arthritis, Biff was in great health. Our other Lab, Jesse, is 13 1/2 years old ...also with arthritis. She will never go on Rimadyl. We have changed her diet to include holistic remedies, and she is doing remarkably well. I am writing this in the hopes that no one else has to go through what we did...."

Borzoi Dies within Days of Beginning Rimadyl Therapy 

From an E-mail received November 23, 2001: 

""I found your website after my Borzoi died suddenly following a course of Rimadyl. What alarms me is that it has been four years since the concerns about Rimadyl began to surface, and yet I was totally unaware of the most serious concerns (sudden, lethal adverse reactions), as was my veterinarian."" 

""Josh, my Borzoi, was 10-1/2 years old and slowing down considerably due to arthritis. We had him on coated aspirin and glucosamine and chondroitin sulfate for six months and then last week when I asked if there was more we could do for him, our vet suggested either Rimadyl or Metacam (not available in the U.S. yet). He said there could be potential problems with long-term use of either of these drugs, but that we would do regular blood tests to catch any such problems before they did any serious damage. I chose Rimadyl because he said he'd seen very good results with it and I thought it would be easier for me to administer a tablet than a liquid medication with Josh. 

I went home with a sample 10-day supply to see if the product had any value before committing to a larger supply. Josh weighed 91 pounds and the dosage was two capsules at 100 mg each per day, in combination with the glucosamine and chondroitin. Within 24 hours the results were dramatic. Josh walked with greater ease and people commented on the new spring in his step. The very first day, he chose a longer route for our walk, where in recent weeks he'd deliberately sought the short cuts. But within three days, he started to slow down a bit. On the fourth evening, he seemed to have lost his appetite. The next morning I found him in great distress, panting and gagging. When I urged him to get up, his hind end totally collapsed and he couldn't move his back legs. 

Our vet made a house call with an assistant and they carried Josh out on a stretcher. X-rays showed his spine was 'like that of a two-year-old.' Our vet said the symptoms suggested a central nervous system problem. Josh did not get any Rimadyl that day. With his condition deteriorating into lethargy and almost paralysis of the hind quarters by that night, our vet gave him a cortisone treatment. The next morning Josh was worse, clearly in misery. He didn't even acknowledge my arrival with any sign of hope or pleasure. Our vet could offer no further treatment suggestions and predicted Josh could be dead within a couple of days. I couldn't bear to see him in such distress and in the absence of any hope of improvement decided to euthanize him yesterday. 

At no time was the subject of Rimadyl raised as a possible cause. Then I recalled a friend a couple of years ago telling me she had met a drug company rep at a conference and the rep had told her one of their canine arthritis drugs was killing dogs. Although I couldn't believe a drug that was known to be killing dogs could still be on the market two years later, I did an Internet search on Rimadyl today only to discover it was this drug she was talking about and that it was still widely in use and obviously still not as well understood as it should be by veterinarians. 

My vet is a thorough, well-respected professional who spends all kinds of time with me and my pets during our visits to explain all the possibilities and options in great detail -- so he wasn't being negligent. We both talked with the Pfizer Canada vet, who kindly but adroitly seized on aspects of Josh's medical history -- a brief episode of neck pain four years ago, a 10-pound weight loss this past year (which may or may not be significant in a member of such a large breed who was a fussy eater) -- to suggest Josh succumbed to an underlying condition rather than Rimadyl. Of course, without an autopsy, there's no way to definitely implicate Rimadyl. However, my vet and I are still suspicious. He says he's 'on the fence' on this one and will definitely approach Rimadyl with far more caution in the future. 

I hope you will pass this information on to people who should have it so as to prevent any more suspicious deaths. Josh's symptoms and story are similar enough to others on this site, that I feel their connection to Rimadyl is more than coincidence. I can't know for sure if the outcome would have been any different without Rimadyl, but if I'd known of all these other cases and the questions surrounding Rimadyl, I wouldn't have chosen to use it on Josh."" Respectfully, Marylu Walters, Edmonton, AB Canada

Rimadyl Given Simultaneously with Prednisone; No Baseline Tests Done; Side Effects Warnings Not Given...Fatal Outcome 


From an E-mail received November 28, 2001: 

"Our Tink was 13 years old....old perhaps in some people's mind but not in ours. On 5/8/01, during a routine exam of Tink, my wife asked our vet if there was anything we could give Tink for her slight limp and suspected arthritis. The vet gave us two sample bottles of Rimadyl. No blood test done. We gave her 75mg twice a day. When it ran out we decided to continue with it, basically because at that time we couldn't see that it was hurting her at all. The vet had already given his blessing to get more if we needed it. 

On 5/30/01, we purchased a large bottle of Rimadyl right from the receptionist at the same animal clinic; we did not have to see the vet to do so. By 7/03/01, Tink didn't seem to quite herself; among other things her energy level had gone down somewhat. So back to the same vet she went. This time he prescribed Prednisone because he said she had an enlarged heart, and he took some x-rays. No mention was made of the Rimadyl. 

On 8/29/01, she was back to the vet because she had been coughing and gagging quite a bit. A different vet at the same clinic saw her and prescribed Cephalexin 500mg. The Rimadyl was almost gone, so my wife asked this different vet about getting another bottle. She also informed this vet (in case he hadn't seen it on Tink's chart), that Tink was also on Prednisone for her enlarged heart. This vet was somewhat puzzled to learn that Tink was taking both medicines at the same time....not because he said they were not compatible with each other but because they both contained anti-inflammatory agents that were basically doing the same thing. He suggested we cut back on the Rimadyl a little. Still no blood tests done on her. We then decreased the Rimadyl to one 75mg a day and most of the time she only got about half of that a day. 

About this time she was also showing some signs of incontinence....a dribble here and there, whenever she got to her feet. Getting to her feet was also becoming much harder. We thought that the incontinence and struggling to her feet were just signs of age. By 11/12/01, we started to noticed to notice a red tinge to some of the urine drops on the floor. So we took her to the vet again. This time, the first vet saw her and said she had a bladder infection and prescribed SMZ TMP Double S, an anti-biotic. We gave her the medicine for a week, along with the other two she was already taking and didn't notice an improvement with the blood in her urine. 

On 11/19/01, when the antibiotic ran out, we called the vet and he said to get some more and try it for another week. Also on this morning she vomited and just didn't want to get up. We were reluctant at first to call the vet because we both had the feeling from talking with him that he would suggest bringing her in and 'putting her down.' By 11/21/01, all she wanted to do was lie down, though she was able to still go outside (after we got her on her feet) and do her business. I think pride in herself was the energy that enabled her to do even that. I called the vet and described the symptoms and his answer was 'She's old.....she's got a lot wrong with her...I had to think about doing the right thing.... he could try and drag out her life for her if that's what we wanted, but it probably wasn't fair to her.' And on and so on. 

On 11/24/01, we stopped the antibiotic because we weren't finding as much blood as before and because I thought she might be having some kind of adverse reaction to the stuff. For the next two days ,we spent all the time with her. She looked so weak and sad, and so very pathetic. The only thing that brought her to a sitting position during that time was if you offered her a snack, which by this time we were giving her all her favorites foods and treats. Once encouraged she would also drink a little. We made an appointment for 3:00 PM last Monday, 11/26/01. I carried her to the car, held her little head in my hands while my wife drove to the clinic. Once there, we still hoped for a miracle. We described again the symptoms that we thought had come on very quickly. But the vet told us that 'her time had come....we were doing the right thing.' He also commented on what we had also noticed, that her stomach had became a little bloated and distended. 

We held her and cried like I'm crying now and she went to sleep for the last time in our arms. I carried her back to the car and she came home for the last time. Yesterday, Tuesday, 11/27/01, trying to get a handle on the heartache and grief, I looked around the Internet at the different 'dog' sites. When I got to srdogs and read about Rimadyl, I was shocked. Tink had vomited, she did have the blood in her urine, she had become somewhat incontinent, she had become weak and lethargic, she was stumbling, struggling and having a hard time getting to her feet and maintaining her balance, and her appetite had decreased a lot.....all in a matter of a few months. 

We have spoken to our vet about our concerns, and after repeating all Tink's symptoms to him again and saying that they seemed to match a lot of the side effects associated with Rimadyl, he said they also matched symptoms of old age in a dog too. He claims he didn't know she was still on Rimadyl because he wasn't the one who handed them to us when we went back twice for the refills.(Makes you wonder about her chart.) He also says that he never would have prescribed the Rimadyl and Prednisone together if he had known Tink was still on the Rimadyl. But he believes through all his 'experience' that the symptoms she had, that had come on so quickly, were not related to Rimadyl, with or without the Prednisone. 'She was just old and her time had come, and we were right in what we did.' When I asked why a blood test was never done during all of this, he said he didn't believe it was worth the money....and that he had dispensed a lot of Rimadyl without any tests. He said that Pfizer may recommend a test before and during, but it is not required. He was sorry that she didn't live to be 16, but 'not all dogs do', he said.""

Black Lab Begins EtoGesic Therapy for Arthritis; Is Switched to Rimadyl.....Then Dies 

From an E-mail received August 13, 2001: 

""Our beloved Betsy, a Black Lab, had a slight problem with arthritis. On June 20, the vet prescribed Etogesic, which, within one week, caused vomiting, diarrhea and loss of appetite. The vet recommended withdrawing the drug, and she immediately improved. The vet then recommended Rimadyl, telling us that there were some adverse effects, but that they were very rare. They tested Betsy's blood and liver, which were both normal, and told us that she was very healthy. 

"Within two weeks of beginning Rimadyl, Betsy began vomiting blood. The next night she passed blood through the bowel and lost all energy; she was unable to walk. I took her to the vet, who kept saying it was probably intestinal cancer and that they would test for it. Each day, she became progressively worse. It was never mentioned that Rimadyl could be lethal to Labs. We were waiting for results of another cancer test when Betsy passed away at the vet's, two-and-a-half weeks after starting Rimadyl. An autopsy showed that both EtoGesic and Rimadyl were implicated in her death. 

Our hearts are broken. We need to do something more to warn others. I urge everyone to please let us know if this has happened to you. We need to get this information to the manufacturers of these drugs and to the FDA, and to get it out to the public, as well." 

Sadly, 
Tom Adams in Memory of Betsy

Rimadyl Consumer Information Sheet NOT Distributed!! Dog Dies of Liver Failure..... 

Report Received April 16, 2001: 

"Hello....I just lost my 8-year-old Lab yesterday. The cause was liver failure. We put her on Rimadyl exactly four weeks ago. She got sick the fourth week --- vomiting, not eating, lethargy.... all the indicators....indicators I subsequently found on the Internet. Unfortunately, I wasn't given a sheet to warn me what to look for. She appeared to have a seizure Saturday night, and we took her to an emergency vet to put her on i.v. meds and fluids. I put her down Easter Sunday morning. The more I read, the more I am sad and disappointed. I would have watched more carefully, had I known more about the risk I was taking. 

I have a case number with Pfizer. They are paying (I think) for the autopsy. I still have many questions....... and have to wonder about liability on Pfizer's part. I'm sure Rimadyl is a very helpful drug. I am, however, also quite sure it is what shortened my dog's life. I feel a blood test should be required before the drug is prescribed, or as a follow up before long-term prescriptions are given. Can you give any suggestions? Where should I look? What should I do? I would like to prevent this happening to other dogs. I would like to do something for them, for their loving owners, and for Snickers."" 

2/14/00 -- "Our most beloved and cherished 14-year-old yellow Labrador Retriever (Manda) is dying as a result of being on Rimadyl for three weeks. The last three days she has been receiving IV therapy in order to stay alive. She has displayed every single symptom that we have read about on various websites as signs of Rimadyl poisoning. Up to this point, she was as healthy as a horse, with the exception of some stiffness in her right hind leg, which our vet originally diagnosed as arthritis and for which she was given Rimadyl. (It was subsequently re-evaluated as a torn ligament.) We are in desperate need of help from anyone who may direct us about treatment . We have read that dogs HAVE recovered from this horrendous plight, and need as much information as we can possibly obtain in order to restore our Manda." 

2/10/01 -- It was when I had read the reactions to Rimadyl on the srdogs site that I realized how ill my dog was. Sadly, the outcome was an unhappy one; he was put to sleep on December 9, 2000. I was too upset to have a post mortem carried out and so can never prove it was about the possible side effects of this drug, which may have caused me to act faster than I did. He had a cruciate ligament operation and I thought the initial symptoms of lethargy and loss of appetite were due to the surgery. It was only then he developed wet eczema (hotspots in the US) that I became concerned it might have been something else. As I am in the UK, I have contacted Pfizer (who paid some of the blood and stool sample costs) and, more importantly, I have lodged a complaint with the Veterinary Medicines Directorate (an Executive member of the Ministry of Agriculture Fisheries and Food) as I was given no information with his prescription of Rimadyl and I feel this is unacceptable."
