rimadyl and liver problems for dog

cats.and.dog

12 years ago

Has anyone had an experience like this. I had my German Shepherd spayed on Tuesday. They gave me rimadyl to give for her pain. 2x daily 75 mg. On Friday she started throwing up clear bile and had no appetite. Took her to emergency and they said she was going through possible liver failure probably from the rim. Bloodwork done before her surgery by my vet showed no liver problems.

I would like to hear that somebody else had a positive outcome from this!

Our dachshund was prescribed Rimadyl to help control the pain of an ear infection. Of course, we were concerned that our dog was suffering, so we simply trusted the vets and we didn't investigate the potential side-effects. Within a couple days of using Rimadyl, our dog was unable to walk due to partial paralysis in his hind legs. He had a terrible seizure that lasted a half-hour. Unfortunately, it didn't occur to us that Rimadyl could have this effect until our 2nd dachshund received a single dose and lost the ability to walk within 12 hours. That is when we started researching and discovered countless stories from others with similar experiences. We are devastated. Please be warned. I know some dogs are helped by Rimadyl /carprofen, but the risks are very real and very serious. These are not "upset stomach" or "lethargy" type of side effects. These are paralysis, liver or renal failure, and death side-effects. Please use a pain management drug with less risky side-effects. If you decide to use Rimadyl, watch your dog very carefully and start with very small doses. It is absolutely horrible to watch your beloved family member suffer because you kept giving them something you thought was going to help them.

"Took her to emergency and they said she was going through possible liver failure probably from the rim."

What kind of testing did they do to reach this conclusion?

No testing but since the blood work done right before her surgery- on the day of- showed normal levels and good liver function then it stands to reason that this drug is the culprit since it is the only thing she was taking. Since my last post her health has deteriorated. She is bleeding into her lungs.

If she is not improved by tonight I will have to consider putting her down. Also, this drug rimadyl has an alarming reputation for causing just this sort of problem in some dogs. I wish I had been told this when they gave me the pills. There is no warning on the bottle and I was given no literature of any kind. I wish I had googled. Why didn't I google rimadyl?!

This is a nightmare! My daughter and I are always marveling at the turn for the better our lives have taken since Pippa came into it. So much happiness! She is the best dog and we are heartbroken.

Here is the basic method I use to manage the freezer. First, I had posted a method to vacuum pack food to prevent freezer burn without buying expensive "Foodsaver" type bags. Labeling is very easy. It is a pain having to write each label every time you freeze something. I use MS Excel formated to print labels on inexpensive pressure sensitive labels, 30 label on one page. Actually there are not that many food that go into the freezer, Pork, pork chop, pork shoulder, pork loin, sirloin, chuck--------etc. Indentfying the date is also easy. Just put on the label 1 to 12. I is January, 2 is Feburary, etc. Peel off one of the labels, stick it on and you are done. The label stays on the plastic bag and will not fall off. You can also do this. you have two label made of the same item, one for the item which goes in the freezer, one goes on a note book. When you look at the note book, you will know what you have in the freezer still not used. When you use that item, you cross it out from your note book. dcarch

K R said, "Carprofen is an NSAID for canines, my senior dog is on it and it works very well! Why wouldn’t you just ask the vet for a prescription? I would never give my dog human drugs." Why? "Are there any potential side effects? Side effects in dogs include gastrointestinal upset, such as mild vomiting, diarrhea, constipation, and temporary lack of appetite, as well as tiredness. More serious side effects include liver, kidney, or gastrointestinal damage characterized by severe vomiting, diarrhea, black or bloody stools, bloody vomit, increased drinking and/or urination, yellow skin or eyes, severe lethargy, and persistent lack of appetite. Other reported serious side effects include neurologic signs such as incoordination, paralysis, seizures, or disorientation, behavior signs such as restlessness, or aggression, skin effects such as itchiness, hair loss, or scabs/wounds, or allergic reactions such as facial swelling or hives. Your veterinarian may see blood abnormalities such as low red blood cell or platelet counts on bloodwork. Carprofen may also affect lab tests, such as thyroid levels, liver enzymes, blood cell counts, potassium levels, kidney values, and bleeding times. In cats, serious kidney effects and gastrointestinal effects have occurred, and is therefore not usually recommended. This moderate-acting medication should stop working in a few days, although effects can be longer in pets with liver or kidney disease." That's why.

In answer to your post, Deb, and to others, I don't exactly use recipes to cook dogfood, but more of a formula. My first ingredient is always meat. I do add some filler to save money, but the amount of filler I use is less than what is in commercial petfood. Also I add calcium to substitute for the bones that a dog would naturally consume along with meat from prey in the wild. Additionally I add digestive enzymes and vitamin/mineral supplement. For instance the food my dogs are eating this week is chicken and rice. I cooked 4 lbs of ground chicken and 4 lbs of ground turkey in a big pot. To this I added about 3 cups of cooked white rice and meat pulled from the bones of a baked chicken and the juice from the chicken. Then I stirred in 3 heaping teaspoons of powdered calcium carbonate (I buy NOW brand at Amazon.com). I also added the powder from about 5 capsules of digestive enzymes and from two vitamin/mineral capsules. These are human grade supplements. It is important when using human vitamin/mineral pills for pets to buy iron-free supplements. Last week my dogs' menu was ground pork and boneless pork chops cut into tiny bites with some cooked macaroni and the same supplements added. Basically this food was made using the same proportions as the poultry mix they are eating this week. I use ground beef sometimes, also liver, and sometimes I whip up an omelet with cheese and meat scraps from about 4 to six eggs and about 1/2 a teasp of calcium. In place of store-bought powdered calcium, you can use ground eggshell. I use it when I have it on hand. I save eggshells in a dish in my freezer and when I have enough, I bake them at 350 degrees for an hour, then grind them into a powder for one minute in a small electric coffee grinder that I bought for this purpose, and store the powdered eggshell in the fridge. Powdered eggshell is mostly calcium carbonate, 90-something percent. For my cat, I feed only chicken, because that is all Miss Picky will eat. I pull the meat into tiny bites and add all the above named supplements (in smaller proportion) as well as a small amount of taurine. Kitty can sometimes be persuaded to eat some tuna or a few bites of other meats, but she tires of it quickly. I hope this is somewhat helpful to those of you wondering about home cooked petfood. I figured out the proportions of calcium to meat sometime ago based on pet nutrition studies somewhere on the web. I fed my two old dogs home cooked for the last 4 years of their lives and they were in good health up until the end when I lost one to cancer and the other to respiratory disease at ages 12 1/2 (the collie) and 14 (my sheltie). My new dogs are doing well on this food, and my 19 yr old cat has been eating home cooked for the past 5 years and is in good health for an old timer. I also thought about a raw diet, because it is definitely the natural food of a dog or cat. Like some others I am sort of squeamish and got cold feet about the idea of feeding bones. I know that if bones are uncooked they are supposed to be safe, but it's so ingrained in me not to feed them that I just wimped out and went the home cooking way instead. I will say that all my cats have been indoor/outdoor cats most of their lives and they certainly have eaten rodents and birds, bones and all, with no ill effects. In fact, I suspect that this partial natural prey diet may have been responsible for their longevity, as they lived to be 23, 21, 20, and 10 (the last having died from an injury) and my current cat is 19 and I expect she will live into her 20s too. So I'd have to say there is a lot to be said in favor of a raw diet, it's just not the way I chose to go.

Rimadyl for short term use in 6 months old pups?
Q
Comments (14)
Hey guys, Thanks to all that took the time to answer. I appreciate it. I know my post was long and I'm not very good at communicating this way. Yes, costs are a consideration... but not the main thing. We have had communication "issues" in the past with this vet and her office staff and we are trying to rectify this. Although, I don't think we are getting anywhere. For instance, when we took the new pups in for the second set of shots (the rescue shelter had given the pups the first set of shots, but we missed the time frame by 6 days (it was unavoidable on our part) so the vet insisted that the first shots wouldn't count). After the exam she sent in a vet tech to finish up and we specifically asked what would be needed on the next visit for puppy shots (what we considered the 3rd set but the vet said they were the second set) and we were told that there was no charge for the actual visit because there was no need for an exam, it was considered just a follow up visit, and then given a list of shots needed. I had it figured at 57 dollars... and that is after i told them that it wasn't just the money due that was the problem, it was not knowing ahead of time and we are not willing to face surprise charges (when possible, of course, we are not talking about emergency situations or diagnostics). So... here we are with the pups in the exam room, on time, according to the vets strict shedule for time allowed between sets of puppy shots and just to be doubly sure I mention this to the vet tech who sees us and the pups before the vet does. She tells me there must be some confusion (picture heavy sighs and eye rolls from DH and I.. here we go again) and I explained to her that the confusion must be on their part, not ours, because we specifically asked on the last visit about this. She tells me this is "impossible'. I tell her it is not only possible but, sadly, highly possible and par for the course. Geesh! She then asks me who the vet tech was on that visit. I tell her I don't know her name (it's hard to keep track, there are new and different employee's, including this one, every time we visit and this is, again, after we have told them that we want all communication on record and that we neeed to know what to expect, moneywise, beforehand... surprises are no longer accepted) but it should be on the record, no? Silly me, eh? We tell her we want to speak with the vet.. she scurries off and comes back just as quickly...says things will be straightened out. Starts to leave again, as she does we spot the vet tech from the previous visit. We tell her that is her, she's the one that gave us the info. Much wispering and not so whipering conversations going on in the hall. At this point it is bordering on the absurd. I open the door and ask the vet to talk to us.. she says take it up with the office manager and walks away. My DH was boiling. Anyway, office manager tells us same thing... it is impossible that anyone could have told us this. At this point door is opened and i see the vet again... she tells me that this is not up for discussion and that if I don't agree with the exam fee and a few other puppy shots that we were, also, told previously that were not needed, that we can go to petco! I was furious and told her that even petco has scheduled shot days and if we left now, the pups would, again, be off the allowed puppy shot period, thus forcing us to negate the 2nd set of shots just as we had to negate the first set. Her reply was that a week or so wouldn't matter!! My DH had taken us to the vets office directly from work... he works construction, very hard work... he had not even had a chance to take his boots off. He was tired to begin with. Now he was exhausted and pis*ed, too. We gave up in sheer frustration. What was supposed to cost 57 dollars now costs us 147 dollars! Ugh! We didn't even have 147 dollars. It simply wasn't in the budget for that week. Don't forget, we did try to budget for this. Also, on the Rimadyl thing, I struggled with the issue when Toby needed it. I knew it was a risk but he was in so much pain that if there were no relief I would have had to put him down. He was crying at night and could never find a comfortable position. The Rimadyl was a miracle drug for him. My concern for the pups is because the vets office says that there isn't much risk for young pups. I'm not sure I believe that. And I do know that there are lots of other meds out there. What I need to know is which ones to ask for and which ones will work with less risk. There, surely, must be standard meds for post surgical pain? As to folks who say that the pups won't need pain meds? Maybe not for 5 to 7 days...but I do believe that they will need some pain meds. I don't subscribe to the thought that they (animals) don't need them even for such things as dew claw removal, neutering and tail docking (as newborn pups or older) and such. I remember when hospitals routinely did circumcision (no anestectic) on human babies. I didn't understand THAT thought process then, never mind that it came from doctors. It took a nurse to prove just how excruciating the pain actually was/is. She instinctively knew that the cries from these babies were cries of pain. Nobody listened to her. She taped recorded the different cries of babies. Clearly, you could hear the terror and pain in the cries. It seems so foolish to me that doctors would think otherwise. I know that when I had abdominal surgery I was very, very sore and in pain for more than 24 hours. I won't over medicate them. I'll observe them and see what they need for how long. But I also won't under medicate them. Hey, maybe I will end up taking the pups somewhere else. Still, I'd like to know ahead of time what pain meds are effective and not risky. Thanks again, Silly

I am unclear... you said the emergency room did NO blood work or testing (very hard to believe)? Why would they then assume it's liver failure or has anything to do with liver or the Rimadyl? A lot of things can happen to the body post surgically that have nothing to do with a drug given at the time. Vomting bile is a very common symptom of just about any illness a dog can get (It has to be one of the top 5 presentations to any emergency clinic for any dog or cat that comes in). Bleeding into the lungs is much more unusual and certainly not on the top of the list of liver failure symptoms.. in fact it is a pretty bizarre symptom of anything but a coagulation defect, something possibly related to exposure to rat bait, DIC from a surgical complication or severe stress of anesthesia, etc. Anyway, I certainly hope some sort of blood test was done to make the conclusion of acute liver failure before they decide your pet's fate on so little information. Blood testing is vital to help figure out what is going on with her and help the doctors treat her proplely. Has a coagualtion panel been run? What symptoms are there aside from vomiting bile (as I said, a very common symptom with just about any illness from eating something irritating, to post op nausea, to kidney disease etc.) and pulmonary hemmorhage (not an easy thing to even diagnose- how did they do that?)? I hope she does OK. Sounds like a very unusual case.

Either way, the makers of Rimadyl need to know of this case for several reasons- one so they can help you and the veterinarians involved treat your pet, to help you pay for your treatment of your pet (if it seems indeed to be related to the Rimiadyl), and also to help prevent future problems in other pets. I have found manufacturers to be extremely helpful in suspected drug reactions to their products, and in most cases, help the client with payment as well as treatment should any relationship even be likely.

I had a recent negative experience with Metacam a few years ago, a very similar drug which I have had very few problems with and like to use, that caused a problem in one of my patients and the company paid for everything that was done to help that patient (still alive and doing well today).

As for safety of Deramaxx versus Rimadyl, I could not disagree more. I have had three patients now put on Deramaxx by various doctors (one was a surgical specialist) that all bleed out or nearly bled out, from perforating ulcers due to Deramaxx. All died though I managed to keep the last one alive for a month. Admittedly all three dogs were older and several had been on Deramaxx for some time. But one was just put on it 5 days earlier, and had no problems before hand with ulcers. The makers of Deramaxx did help out with that case and did admit Deramaxx was likely to have been involved in the perfortationg uclers. Never seen a dog die of Rimadyl related ulcers.. nor even see a dog get ulcers from taking Rimadyl.

I have only had a dozen or so patients that have been on Deramaxx so three deaths out of that many is a pretty bad percentage. I have not perscribed it nor do I plan to.

ON the other hand, I have over the years had well over 1000 dogs on Rimadyl (many on it for many years) and seen very few problems with this drug, even with massive overdosing (eating an entire bottle of Rimadyl is not an uncommon occurence with dogs, particularly those able to get onto counters). Not seen any serious problems though sometimes it can make a dog sick to its stomach (as can just about any drug). But I will not deny that serious side effects exist out there somewhere, though there are problems that occur with just about any drug there is if you look hard enough. But you will never convince me Deramaxx is safer than Rimadyl. Even the experts in the field say so- Dr. Dawn Boothe, probably one of the worlds experts in veterinary pharmacology, said in a lecutre at a conference not that long ago, that Rimadyl had easily the best safety track record of all the nonsteroidals and seemed to have the largest safety margin as well (least likely to cause problems if overdosed). Aspirin, which we all take willy nilly, has one of the worst safety records with dogs, yet hardly anyone seems to worry about giving their dog an aspirin now and then.

One of the problems with Rimadyl is it is prescribed 10x more often than all the other nonsteroidals combined, so it is not surprising there are more cases reported of problems with it compared to some of the other drugs (but if you look into Deramaxx problems you might be even more surprised). However, even Deramaxx is relatively safe if you consider how many dogs take it compared to how many have serious problems with it as those I experienced. I think I just happened to come across 3 unusual cases... But that's enough to make me afraid of the drug, especially when I have had very few bad experiences with the others I use (Rimadyl, metacam and Ferocoxib). To me it just doesn't make sense to use it when Rimadyl is obviously safer.

As to which works better for pain or inflammation is much more of a debate and is very subjective as dogs cannot tell you how they feel. We just have to watch and see their responses. Sometimes one nonsteroidal just seems to work better than another for one dog, while another dog will respond differently. Just as some people find Alleve (naprosyn) works better than Advil (Ibuprofen) and other people find the opposite.

Anyway, back to your pet and her illness. I sure hope they can help get her health back. I have been an emergency clinician for years now and it is very scary to have dogs develop severe illnesses after relatively common procedures. It can make you nervous about any procedure- and it should! Any surgery or drug can have serious potential consequences and we need to be a bit afraid all the time or we are going to be making careless mistakes and approach these situations with too little concern.

I won't debate this issue. I am only here to share my experience and what our breeder advised us. When our vet wanted to prescribe Rimadyl, our breeder shared some of her horrific experiences with the drug. She has been breeding Mastiffs for over 25 years now so her experience and knowledge is extensive. Our breeder recommended Deramaxx.

We tried the Deramaxx and it was very effective in treating our 8 year old Mastiff. It made the last few years of his life much more comfortable and he lived to a ripe old age for a Mastiff - 11.3 years.

Obviously the OP's German Shepard may be allergic to the Rimadyl so it might be wise to keep an alternative in mind.

Both drugs are NSAIDS (Non Steroidal Anti Inflammatory Drugs)and both have side effects. However, the reports of adverse side effects are drastically more common with Rimadyl than with Deramaxx.

And while you "couldn't disagree more" there are numerous anecdotal reports of the dangers of Rimadyl. I don't know what world you live in lzrddr maybe an alternate reality.
Vomiting is a BAD SIGN with Rimadyl, take this example:
USA Today story on NSAIDS:
"Rimadyl's fast start had a dark side: Reports of dogs suffering liver damage and other effects began pouring in. One of those dogs was George, a 12-year-old chocolate Labrador retriever owned by Jean Townsend of Johns Island, S.C.

She saw the Rimadyl ads and asked her veterinarian whether Rimadyl could help George, who, while seemingly healthy, was moving slower. Rimadyl seemed to work, but after several weeks, George sometimes couldn't move. He started vomiting and had blood in his stool. Within 30 days of starting Rimadyl, George was put down. An autopsy showed liver damage, ulceration and bleeding.

"I had no earthly idea I was killing my dog," says the 68-year-old retired government worker.

Townsend says she wasn't warned of the risks and didn't ask, trusting her veterinarian. She refused Pfizer's offer of $249 and filed a lawsuit in 1999 that was joined by 300 others.

Pfizer settled in 2003 to avoid costly litigation, it says. Each plaintiff received about $1,000. Pfizer didn't admit wrongdoing and says it informed the FDA of side effects as soon as they were reported.

"We were incapable of informing the world of what we didn't know," spokesman Robert Fauteux says.

Pfizer updated Rimadyl's label twice, the last time in 1999 noting that death occurred in rare instances. That year, it stopped TV ads. Today's print ads include the death warning."

Turns out that many pet owners live in blissful ignorance and just kill their pets with good intentions. Rather than doing the due diligence and getting the info they need to make informed decisions.

All NSAIDS have risks but it turns out the Rimadyl is one of the more lethal drugs on the market.

The OPs dog didn't vomit - it was bile. Hence the question on other symptoms and what testing was done. Sounded like a bit of leap to conclude liver failure based on bile and inappetance.

"reports of adverse side effects are drastically more common with Rimadyl than with Deramaxx."

Could that be because Rimadyl was the first NSAID for dogs and has been out longer and therefore more adverse reaction reports due to time on market? All drugs need to be assessed risk:benefit. Your dog might have done just as well on the Rimadyl as on the Deramaxx. OPs dog may have had same result on Deramaxx or on no drugs at all, since still not clear on the cause or tests done or dx. Correlation does not imply causation.

Hi All-

I think I misunderstood what Cynthia was asking. There was blood work done when I took Pippa on Friday that determined that there were serious goings on with her liver. Her ALKP went from 28 U/L before surgery to 2973 U/L four days after surgery and six rimadyl tablets. Her ALT went from About bleeding into the lungs. The doctor who saw her on Saturday I believe said that her labored breathing was due to fluid in the lungs and that this was probably blood. How she determined that I do not know. In all of her gagging Pippa never coughed up any blood that I saw.

This is what was determined through testing and observation:

-X rays showed no GI obstruction
-Ultrasound showed coarse liver- no other abnormalities
-Diagnosis: acute liver failure, coagulopathy. Pippa was given a transfusion. Given poor prognosis.

Pippa was given a lot of treatment in the form of IV fluid, Vitamin K, antibiotics, pain meds that would not affect her liver.

She was able to stay home with me last night. She took a small amount of food through a syringe. She still had episodes of labored breathing but then there were also long stretches of relatively peaceful breathing while asleep. She even showed a little of her old personality when I put on her leash to take her out to pee.

I took her back to the vet this morning where she will stay till 11:30 tonight. The vet called about an hour ago to let me know some good results. Her clotting times have returned to normal. Other levels are returning to normal. ALT now at 682 and ALKP now at 1400. Hopefully these will continue to go down. Also she has no fever today. She mentioned some other things but I don't have time to list all of it right now and some of it is a bit confusing for me honestly. She said she thinks Pippa suffered severe hepatotomy rather than acute liver failure.

I hope I am relaying all of this correctly. I am so happy at the good news although the vet also did mention the possibility of chirossis developing further down the road. She kept mentioning Sega Palm poisoning over and over again. I don't know if that's what she thinks happened and when I told her I don't have any of the stuff in or around my house she said it was just an example. Then she just kept mentioning it some more. I'm thinking that they want to blame this on Sega Palm.

I appreciate all the replies.

I'm sorry your dog is sick but glad that she's recovering.

I have 3 of my own dogs and so many patients I can't count on Rimadyl every single day.

Some dogs do have horrible reactions to it, but that is more common in Labs than in other breeds.

Deramaxx is the NSAID most likely to cause GI ulcers with long-term use. I usually switch those dogs to rimadyl or meloxicam and they are fine. I like deramaxx for short-term pain relief though.

That said, every individual is different. Just like in people, one drug may work better than another, and one drug may cause problems for one person or animal and another animal or person can be 100% fine.

One of my patients when into acute liver failure for no reason whatsoever. At least none that anyone could find. $35,000 later all I know is the immune functioning part of her liver isn't 100% recovered- the dog gets really bizarre infections (one time cultured horse strangles) for no good reason. But we never did determine a cause.

I think the timing of the sudden illness with rimadyl is extremely suspect at least. I would certainly suspect the rimadyl. I'd also report the problem to the manufacturer so there is a record of it although we know this is possible.

Sabal Palm is a highly liver toxic plant that could also explain what Pippa is going through. A dog doesn't have to eat much of this plant to die from liver failure. We don't see too much of that here because it is not a very hardy plant but further south it definitely happens a lot. Mushroom toxicity is another possibility.

The only way to have known for sure what caused the problem is to have had her stomach contents analyzed. That's kind of a useless expenditure though- I'm sure this treatment isn't cheap and it's better to treat than to find the cause in this case.

In any case of liver failure, there is possibility of permanent damage. The good thing is that the liver is a very regenerative organ, so there is good chance there won't be problems. Also dogs don't need a lot of working liver to survive. I would just be VERY careful of avoiding anything that can affect the liver in the future. I'd not give her NSAIDs of ANY type ever again.

Hope she continues to do well.

Rimadyl killed people - which is why it is no longer on the market for people. I hate Rimadyl and will ask my vet to substitite any other pain killer. Ask your vet for Medcam, vicodin or something else. Most vets dont like prescribing vicodin but I gave my dog half a dose on and off for 13 years due to a botched surgery on his leg and he did great on it. His orthopedic surgeon even stated it was safe. Good luck

Does sound like acute hepatic disease, and an NSAID would be certainly suspect as well. Hope Pfizer was contacted. Never said that this could NOT be related to the Rimadyl, but saying it IS for sure does not make it so, either. Sago Palms (not palms, but cycads actually.. and NOT Sabal Palms, which are completely non-toxic and are true palms) are extremely hepatotoxic, but if you don't have one, then that certainly rules that out as a possibility. Glad your pet is recovering- thankfully liver is one of the few organs that can regenerate so your pet may make 100% recovery. Let's hope so. I would, just in case, avoid all NSAIDS in the future (including Rimadyl, Deramaxx, Metacam, aspirin etc.). Your pet may have an acute sensitivity to that form of medication.

Vicodin has acetominophen in it, a risky drug (basically tylenol) to be giving a dog for any length of time, though single doses are probably OK now and then. That one has been shown to cause liver failure in dogs with any prolonged use (far more dangerous than most NSAIDS). So careful with that one.

The reason there are so many more anecdotal stories of Rimadyl toxicity is it is used, as suggested above, well over 100x more often than all the other NSAIDS combined. So more use, more stories. Had Deramaxx gotten onto the market first, then I'm certain it would be the other way around. Metacam has a longer history of use than both, but unfortunately did not get its OK for use in the US until more recently. I have taken the human form of that myself, though I find Advil works better for pain for me.

Many veterinary drugs have idiosyncratic effects in people and that is why they are not used in people- does not correlate in any way, necessarily to safety problems in pets.. one of the best, safest and most used (probably overused) antibiotics in pets, Baytril, causes people to seizure and can't be used in humans. But that does not mean it is unsafe for pets. Just as Acetominophen is pretty safe in people but one dose will kill a cat. Animals and people are not the same things.

The information, as well as the misinformation is out there. You can always ask your veterinarian, but you should be aware there are very few drugs in either veterinary medicine or human medicine that are 100% safe. There will always be some one or some pet that reacts differently to most of the others- that is true with antibiotics, antihistamines, cortisones, heart and stomach medications etc. as well as with non-steroidal anti-inflammatory meds.

You see the ads all the time on TV for this new drug and that one, though now the TV ads all list all the possibly side effects (including death)... but does that keep them from being used? Not in most cases, because the alternative is a poor quality of life, either due to pain or some other unpleasant situation (infection, inflammation, cancer etc). I have seen several cases of fatal or nearly fatal results from using common antibiotics, flea prevention products, sedatives etc... all ones that are given out like 'water' by many physicians and veterinarians. Be we keep on using them since in MOST cases they work well and help the problem.

Rimadyl comes with a handout by Pfizer made specifically for the client that ideally should be sent home with each client so they can read about the possible side effects and what to look for. Some of the other super commonly used drugs have these, too.

Practicing medicine is always fraught with unexpected results and as safe a drug as something like Carprofen is, there are always going to be patients that cannot tolerate it... as there are with every other non-steroidal drug on the market (including Aspirin). We always are looking and hoping for 'perfect' drugs but so far I know of none that have come along. If one does, I will be using that one myself, I am sure.

Our8 year old Chesapeake was given rimadyl for arthritis on Saturday, Monday diarrhea in house, Tuesday diarrhea and vomiting, Wednesday severe vomiting, I mean severe, lots of blood. Vet said lucky to save her. She is at vet's on ivs and now worried about liver damage. Please get the word out on these terrible side effects.

The problem with NSAIDs is that when they are used continuously over time, they can cause bleeding, ulcers, and other side effects. Personally I will use rimadyl for short term, ie for post-op pain, but I would not be comfortable using it continuously. When I have had to have an animal on an NSAID long term (a dog on aspirin and several horses on bute) I usually take 4 days off the medication every 10 days - two weeks on, to allow the body to reset itself and prevent possible cumulative ill effects.

Tramadol is a good alternative to rimadyl. It is an effective pain medicine although it lacks the anti-inflammatory effects of the NSAIDs.
