Celecoxib for African Grey Parrots: Uses, Dosing & Side Effects

This information is for educational purposes only. Never give your pet any medication without your veterinarian's guidance. Dosing, frequency, and safety depend on your pet's specific health profile.

Celecoxib is a nonsteroidal anti-inflammatory drug (NSAID) in the selective COX-2 inhibitor family. In birds, it is used off-label by avian veterinarians to help reduce pain and inflammation. Merck lists celecoxib among drugs used for osteoarthritis in birds, which confirms that it has recognized avian use even though it is not specifically labeled for parrots. (merckvetmanual.com)

For African Grey parrots, celecoxib is not a medication pet parents should start on their own. NSAID handling can vary a lot between species, and Merck specifically notes that NSAID metabolism and elimination differ significantly by species, so doses should not be safely extrapolated from one animal to another. That matters in parrots, where even small dosing errors can become serious. (merckvetmanual.com)

Your vet may choose celecoxib when they want an oral anti-inflammatory option and have a specific reason to use it instead of another bird medication such as meloxicam. In practice, the decision depends on the bird's diagnosis, hydration status, liver and kidney health, appetite, and any other medicines already being used. For African Greys, that individualized plan is especially important because they are long-lived parrots that may need careful monitoring during longer treatment courses.

In avian medicine, celecoxib is most often discussed for pain and inflammation associated with musculoskeletal disease, including arthritis and other chronic inflammatory conditions. Merck's bird osteoarthritis table includes celecoxib as one of the oral options used in birds. (merckvetmanual.com)

Avian veterinarians may also use celecoxib as part of a broader plan for inflammatory neurologic or gastrointestinal disease, including some cases associated with avian bornavirus/proventricular dilatation disease (PDD). This does not mean celecoxib cures the underlying disease. Instead, it may be used to help manage inflammation and improve comfort as one part of supportive care. (amccorona.com)

For an African Grey parrot, your vet might consider celecoxib when there is stiffness, painful movement, reduced climbing, reluctance to perch, or inflammation seen on exam or imaging. It may also be considered when a bird needs ongoing anti-inflammatory support and your vet believes the expected benefit outweighs the risks. The exact reason for use should always be clear, because NSAIDs are meant to manage symptoms and inflammation, not replace diagnosis or supportive care. (merckvetmanual.com)

Celecoxib dosing in birds should come only from your vet, because avian NSAID dosing is species-specific and case-specific. Merck lists a bird dosing range of 10-30 mg/kg by mouth once daily to twice daily for osteoarthritis in birds. Other avian references surfaced in search results describe narrower example ranges such as 10 mg/kg by mouth every 24 hours or 10-15 mg/kg by mouth every 24 hours, which shows why your vet may choose a starting point within a broader published range rather than using one fixed dose for every parrot.

African Grey parrots commonly weigh roughly 400-550 grams, so even a small change in body weight can change the measured dose meaningfully. For example, a 450 gram bird would receive 4.5 mg at 10 mg/kg or 13.5 mg at 30 mg/kg, which is a big difference for a small patient. That is one reason compounded liquid formulations are often used in birds when your vet needs precise oral dosing. (merckvetmanual.com)

Give celecoxib exactly as prescribed. Do not change the dose, frequency, or duration on your own, and do not combine it with another pain reliever unless your vet says to. If your African Grey misses a dose, call your vet or pharmacist for instructions rather than doubling the next dose. Birds can decline quickly when appetite drops or dehydration develops, so any vomiting, regurgitation, black droppings, marked lethargy, or sudden weakness after dosing should prompt a same-day call to your vet.

Like other NSAIDs, celecoxib can cause stomach, intestinal, liver, or kidney side effects. Cornell's NSAID guide says the most common NSAID-related problems generally involve the stomach, liver, or kidney, and the FDA notes that NSAIDs as a group may affect the kidneys, liver, and stomach and intestines.

In an African Grey parrot, side effects may look different than they do in dogs or cats. Pet parents may notice reduced appetite, less activity, fluffed posture, weakness, regurgitation, diarrhea, darker droppings, increased urates, or dehydration. Serious NSAID reactions can include gastrointestinal ulceration or bleeding, kidney injury, and liver problems. (merckvetmanual.com)

See your vet immediately if your bird stops eating, seems unusually sleepy, strains, passes black or bloody droppings, vomits, or appears suddenly unstable on the perch. Because parrots hide illness well, even subtle changes matter. If your African Grey has had prior NSAID sensitivity, kidney disease, liver disease, dehydration, or poor appetite, make sure your vet knows before treatment starts. (vet.cornell.edu)

The most important interaction rule is that celecoxib should not be combined with another NSAID or a corticosteroid unless your vet specifically directs it. Cornell's NSAID guide warns against giving an NSAID together with aspirin, other NSAIDs, or corticosteroids such as prednisone or dexamethasone unless specifically instructed by your veterinarian. Combining these drugs can raise the risk of stomach and intestinal injury. (vet.cornell.edu)

Merck also notes that NSAIDs are often highly protein-bound, so they can compete with other highly protein-bound drugs. In real-world avian care, that means your vet should review all medications and supplements your bird receives, including compounded drugs, liver support products, and over-the-counter human medications kept in the home.

Use extra caution if your African Grey is dehydrated or is taking other drugs that may stress the kidneys, liver, or gastrointestinal tract. Before starting celecoxib, tell your vet about every medication, supplement, and recent treatment your bird has had. That includes meloxicam, aspirin, steroids, antibiotics, antifungals, and any recent injectable pain medicines. A full medication review is one of the safest ways to lower interaction risk.
