Is Previcox Safe for Dogs?

Previcox is a non-steroidal anti-inflammatory drug (NSAID) used to relieve pain, swelling, and stiffness caused by osteoarthritis in dogs. Many people know that common pain medications have the potential to cause kidney failure and death in dogs, but can Previcox kill a dog?

Previcox Killed My Dog

“My dog was prescribed Previcox for arthritis, and it killed her. She had taken the drug for several weeks, and then she got very ill. She went into kidney failure, which is a listed side effect of Previcox.”

“I lost my best friend today, my 11-year-old yellow lab, to Previcox. She was prescribed the drug by her vet for arthritis. She got sick almost immediately, not eating and throwing up. I took her off the drug but it was too late. Be careful of this stuff!”

“My dog, a two-year-old Morkie (Maltese/Yorkie mix) named Buster, died suddenly today. He was given Previcox for a week for pain related to an old back injury. Today he had his second dose and within 30 minutes of taking it, he started having trouble breathing and was lethargic. Within another hour he was dead. I am in shock, but also wondering if the Previcox could have contributed to this sudden death?”

Previcox killed my dog?

Side effects are rare but may include vomiting, diarrhea, decreased appetite, or lethargy. More serious side effects include ulcers, gastrointestinal bleeding, kidney damage, and liver problems; contact your veterinarian immediately if you suspect your pet is experiencing any of these side effects.

An allergic reaction may occur when your dog’s immune system identifies Previcox as a foreign invader and attacks it. This response triggers the release of histamines and leads to symptoms such as swelling of the face, lips, tongue, or throat; hives; trouble breathing; pain; vomiting; diarrhea; lethargy; weakness and collapse. If you notice any of these signs after giving your dog Previcox and suspect an allergic reaction, seek emergency veterinary care for your pet immediately.

Previcox may interact with other medications including corticosteroids or anticoagulants such as warfarin; do not use this medication without first talking to your veterinarian if your dog is taking any medications or supplements. Be sure to tell your veterinarian what other medication you are giving to your pet.

In addition, Previcox is not recommended for long-term use because of its potential toxicity to the kidney and liver. Animal studies have shown that long-term use may result in progressive renal damage at doses below those required to cause gastrointestinal ulceration.

“I just lost my dog yesterday because of this. I had him on Previcox for a few weeks and thought he was doing OK. I noticed him scratching his nose on the floor last week, but didn’t think much of it. He also had some hair loss on his nose and thought maybe he got into something outside.

On Saturday night, he started scratching his ears and shaking his head so bad that I couldn’t get him to stop. By Sunday morning, he was lethargic and not eating or drinking water. On Monday morning I took him to the vet who said he had an allergic reaction to the Previcox and gave him a shot of prednisone in his neck.

He seemed better that afternoon, but by Tuesday morning he was back to his lethargic self and not eating or drinking again. When I called my vet, she said if he hadn’t improved by Wednesday, we should consider having him put down. Well, by Wednesday morning, my dog could barely walk or open his eyes without them tearing up badly. He would only sit up for about 5 minutes before laying back down again in the same spot with his eyes closed and would not respond to anything around him unless you touched him.”

How quickly does PREVICOX work in dogs?

PREVICOX reduces inflammation in dogs within hours. You will see a difference in your dog’s pain and lameness after the first dose. A single dose of PREVICOX works for up to 24 hours.

The drug is best given orally at least 30 minutes before a meal. Some dogs have experienced gastrointestinal upset after taking PREVICOX, so you may wish to give the pill with food or a treat to decrease this risk.

Is there an alternative to Previcox?

The first choice would be Rimadyl (carprofen). It is a similar NSAID (non-steroidal anti-inflammatory drug) that can control pain and inflammation in dogs with arthritis. It has the same potential side effects as Previcox and should not be used if your dog is allergic to aspirin or other NSAIDs.

If you can’t use Rimadyl, there are two other effective alternatives: Deramaxx and Metacam. Both are prescription drugs and both have side effects that you should discuss with your veterinarian.

Many veterinary neurologists prescribe gabapentin as an alternative to NSAIDs for older dogs with arthritis. It doesn’t have any of the side effects of NSAIDs, but it does take longer to become effective.

Other alternatives include fish oil, acupuncture, massage therapy, chiropractic care, and physical therapy. Some vets use Adequan injections plus an NSAID to treat arthritis in dogs; many people believe this increases the risk of serious side effects without doing much good.

Previcox reviews from dog owners

Reviewers say Previcox works very well to control their dog’s joint pain and inflammation. They also love that only one tablet is needed per day, and many dogs take it with no problems. However, a few reviewers note that their dog had side effects on Previcox, such as upset stomach or bloody diarrhea. We also found a warning letter from the FDA regarding a high rate of serious adverse side effects in dogs taking Previcox.

“I have been using Previcox for my 12-year-old Labradoodle for the last 3 months and it has made a world of difference. She used to limp and limp, walk slowly, and could hardly make it up the stairs. Now she’s jumping up on the bed at night, running full speed around the yard… and most importantly, she’s not in pain. The only complaint I have with Previcox is that it’s expensive!”

“I have a 13-year-old border collie who has been limping on one of her front legs and chewing at her paw pads for some time now. The Vet diagnosed arthritis and prescribed Previcox. Within days of beginning the medication, she was walking without limping, and has not chewed her paws since.”

“It works great in conjunction with a glucosamine supplement to help control my dog’s chronic arthritis symptoms.”

“My dog has arthritis and this helps her so much. She’s not as grumpy and she has more energy. It’s great stuff.”

“Not only does it help with the pain relief for my arthritic lab, but it also helps reduce inflammation in her joints.”

Conclusion of Previcox for dogs

The Previcox brand of firocoxib is an NSAID and prescription medication that treats pain and inflammation associated with osteoarthritis in dogs. Like all NSAIDs, side effects are possible with Previcox. These side effects include loss of appetite, vomiting, diarrhea, black or tarry stools, seizures, and breathing problems. If your dog experiences any of these side effects while taking Previcox, contact your veterinarian right away.

Other side effects may also occur in some animals. If your dog experiences any other unusual reactions when taking Previcox, contact your veterinarian.

Generally speaking, the use of Previcox should be limited to a 4-week treatment period and the lowest effective dose should be used to reduce risk. Serious adverse events are more common with higher doses of Previcox so it’s important to monitor your dog’s progress carefully during use.

Previcox should not be used in dogs that are allergic to it or any of the ingredients in the product.

It should be used with caution in dogs that have kidney disease, bleeding disorders, stomach ulcers, and those that are dehydrated.

Tell your veterinarian what other medication you are giving to your dog. Quite often your veterinarian may prescribe two different medications, even if a drug interaction may occur. In this case, your vet may vary the dose and/or monitor your dog more closely. The following medications can potentially interact with Previcox: aspirin or other NSAIDs (including carprofen), steroids (such as prednisone), and ACE inhibitors (used for heart disease).

  1. It doesn’t state on this that the manufacturers of PREVICOX say it is not suitable for dogs under 12.5lbs as you can’t get an accurate dose. My vet gave my Yorkshire terrier a dose of half a 57 mg tablet which is the dose for a dog from 12.5lbs to 18lbs. My dog was 5lbs after two weeks my dog took seriously ill and died later that day. My vet told me this drug was ok for my dog also she didn’t do any blood or urine test on my dog before giving them. My dog wasn’t ill before taking these tablets it ran all day long and played she was 12. I told my vet that I know it was PREVICOX that killed her and she said my dog had a heart problem but never mentioned anything was wrong with my dog’s heart at any other appointments and she wasn’t on any other medication. I took her to the vet because I thought she might have a bit of arthritis in her front leg.

  2. The vet gave my dog Previcox and she was dead within 18 hours. I don’t understand how a vet could know about this medicine and still give it to animals! My dog vomited a few times and laid down to rest for the rest of the night. When I tried to wake her up the next morning, she was very lethargic. We took her straight in and her kidneys were totally shut down. She was in really bad shape and we had to have her euthanized. The vet would not answer our phone calls after we went home. When we went to pick up her cremains, we asked to speak to him and he would not come out to speak to us. His vet tech told us that we should have let them know that she threw up. She tried to blame it on us!

    It’s a shame that we can’t sue these companies and make them pay for the pain our animals went through! We were devastated at losing her!
