What should I tell or ask my veterinarian before giving Previcox to my dog:

Talk with your veterinarian about:

  • The signs of canine arthritis you have observed in your dog, such as limping or stiffness.
  • The importance of weight control in the management of arthritis in dogs
  • What tests might be done before Previcox is prescribed
  • How often your dog may have to be examined by your veterinarian
  • The risks and benefits of using Previcox

Tell your veterinarian if your dog has ever had one or more of the following medical problems:

  • Any side effects from taking Previcox or other NSAIDs
  • Any digestive upset (vomiting and/or diarrhea)
  • Any kidney disease
  • Any liver disease
  • Any allergies your dog had in the past or other medical problem

What happens if I miss giving a dose:

Give the missed dose as soon as possible. However, if it is almost time for the next regularly scheduled dose, skip the missed dose and give the next one as directed. Do not give a double dose of the medication.

Possible side effects of Previcox:

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

It is important to stop treatment and contact your veterinarian immediately if you think your dog has a medical problem or side effect while taking Previcox tablets.

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.


Store Previcox at room temperature, away from moisture and heat.


Previcox is convenient and easy to administer. It comes in a BBQ-flavored chewable tablet that dogs like and can be given with or without food. Previcox is available in two sizes. Your veterinarian will prescribe the correct dosage based on your dog’s weight. Most dogs will take Previcox chewable tablets from your hand, but you can also place the tablet directly into your dog’s mouth. Make sure to always follow your veterinarian’s recommendation precisely and keep plenty of water available for the dog while giving this medication.
