Previcox is a non-steroidal, anti-inflammatory drug (NSAID) prescribed by your vet to treat your canine companion's pain and inflammation caused by osteoarthritis. It can also help control postoperative pain and inflammation often associated with soft-tissue and orthopedic surgery. This medication comes in a chewable tablet form, which means it can be easily crushed up and disguised in your pet's favorite food.


Previcox (firocoxib) Chewable Tablets are indicated for the control of pain and inflammation associated with osteoarthritis and for the control of postoperative pain and inflammation associated with soft-tissue and orthopedic surgery in dogs.

Possible Side Effects

Adverse reactions can occur and may include vomiting, diarrhea, decreased appetite, dark or tarry stools, increased water consumption, increased urination, pale gums due to anemia, yellowing of gums, skin or white of the eye due to jaundice, lethargy, incoordination, seizure, or behavioral changes. Serious adverse reactions associated with this drug class can occur without warning. Pet parents should be advised Previcox therapy and contact their veterinarian immediately if signs of intolerance are observed.

Drug & Food Interactions

Firocoxib should not be taken with other nonsteroidal anti-inflammatory drug or corticosteroids.


This product cannot be accurately dosed in dogs less than 12.5 pounds in body weight. Consider appropriate washout times when switching from one NSAID to another or when switching from corticosteroid use to NSAID use. As a class, cyclooxygenase inhibitory NSAIDs may be associated with renal, gastrointestinal and hepatic toxicity. Sensitivity to drug-associated adverse events varies with the individual patient. Dogs that have experienced adverse reactions from one NSAID may experience adverse reactions from another NSAID. Patients at greatest risk for adverse events are those that are dehydrated, on concomitant diuretic therapy, or those with existing renal, cardiovascular, and/or hepatic dysfunction. Concurrent administration of potentially nephrotoxic drugs should be carefully approached and monitored. NSAIDs may inhibit the prostaglandins that maintain normal homeostatic function. Such anti-prostaglandin effects may result in clinically significant disease in patients with underlying or pre-existing disease that has not been previously diagnosed. Since NSAIDs possess the potential to produce gastrointestinal ulceration and/or gastrointestinal perforation, concomitant use of Previcox Chewable Tablets with other anti-inflammatory drugs, such as NSAIDs or corticosteroids, should be avoided.

Can Previcox (Firocoxib) Be Given With Other Medications?

Previcox should not be given with other NSAIDs (for example, aspirin, carprofen, etodolac, deracoxib, meloxicam, or tepoxalin) or corticosteroids (for example, prednisone, cortisone, dexamethasone, or triamcinolone). Tell your veterinarian about all medications that you have given your dog in the past, and any medications that you are planning to give. This should include other medicines that you can get without a prescription or any dietary supplements. Your veterinarian may want to check that all of your dog’s medicines and supplements can be given together.

How Do I Give Previcox (Firocoxib) To My Dog?

Previcox should be given according to your veterinarian’s instructions. Do not change the way you give Previcox to your dog without first speaking with your veterinarian. Your veterinarian will tell you what amount of Previcox is right for your dog and for how long it should be given. Most dogs will take Previcox chewable tablets from your hand, but you can also place the tablet directly into your dog’s mouth. Previcox may be given with or without food.

Can Previcox (Firocoxib) Be Used For People Or Other Animals?

Previcox is designed specifically for dogs. As such, people should not take Previcox or administer it to any animal other than a dog as prescribed by your veterinarian. Keep Previcox and all medications out of the reach of children. Call your physician immediately if you or a member of your family accidentally ingests Previcox.

What Should I Do In Case My Dog Consumes More Than The Prescribed Amount Of Previcox (Firocoxib)?

Consult your veterinarian immediately if your dog consumes more than the prescribed amount of Previcox.

Are There Possible Side Effects That May Occur In My Dog During Treatment With Previcox (Firocoxib)?

Previcox, like other NSAIDs, may cause some side effects. Serious side effects associated with NSAID therapy in dogs can occur with or without warning. The most common side effects associated with Previcox therapy involve the digestive tract (vomiting and decreased food consumption). Liver and kidney problems have also been reported with the use of NSAIDs. Look for the following side effects that may indicate your dog is having a problem with Previcox or may have another medical problem in addition to arthritis.

  • Vomiting.
  • Change in bowel movements (such as diarrhea or black, tarry or bloody stools).
  • Change in behavior (such as decreased or increased activity level, lack of coordination, seizure, or aggression).
  • Yellowing of gums, skin, or whites of the eyes (jaundice).
  • Change in drinking habits (frequency or amount consumed).
  • Change in urination habits (frequency, color, or smell).
  • Change in skin (redness, scabs, or scratching).
  • Unexpected weight loss.
