Deramaxx™ (deracoxib)

PetMD’s medications content was written and reviewed by veterinary professionals to answer your most common questions about how medications function, their side effects, and what species they are prescribed for. This content shouldn’t take the place of advice by your vet.

What is Deramaxx®?

Deramaxx^® (deracoxib) is an FDA-approved non-narcotic, non-steroidal anti-inflammatory (NSAID) prescription medication for canines. It is used primarily for the treatment of post-operative pain and inflammation caused by orthopedic and general surgery, including dental surgery. It is also used to treat inflammation associated with arthritis, and may also be used to control fevers and inflammation caused by other conditions.  

In dogs, Deramaxx^® may offer some anti-cancer effects through off-label use. It can be used in combination with some chemotherapy medications to treat a particular bladder cancer called a transitional cell carcinoma (TCC) and a blood-based cancer called hemangiosarcoma. The term off- or extra-label means that a medication is used in a way or in a particular species that is not specified on the medication label. While veterinarians often prescribe medications for off-label uses, your veterinarian will determine whether Deramaxx^® is right for your pet.

How Deramaxx® Works

NSAIDs block the production of natural chemicals that trigger inflammation—called a COX pathway. Some COX pathways are helpful with digestion, kidney health and clotting, but Deramaxx^® blocks significantly more of the inflammatory chemicals than the beneficial ones. Because Deramaxx^® can still partially inhibit the beneficial chemicals, especially at higher doses, make sure to speak with your veterinarian about prescription instructions and follow those directions closely.

Deramaxx® Directions

Follow the directions on the drug label or as provided by your veterinarian. This medication is given at different dosages based on the condition for which it is prescribed. Generally, your veterinarian may recommend giving the medication once daily by mouth. Deramaxx^® can be given with or without food, but giving it with food can help to prevent digestive system upset. As determined by your veterinarian, use the lowest effective dose for the shortest duration consistent with your pet’s individual response.

Missed a Dose?

Speak with your veterinarian about what to do if  you forget to give a dose of Deramaxx^®. Generally, they may advise you to give it when you remember, or,  if it is almost time for your next dose, to skip the missed dose and resume your normal dosing schedule. In most cases, do not give extra or double doses.
