Robenacoxib 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.

Robenacoxib is a prescription nonsteroidal anti-inflammatory drug (NSAID). In dogs and cats, it is sold under the brand name Onsior and is used to reduce pain and inflammation. It works by blocking cyclooxygenase pathways involved in inflammation, with relatively greater COX-2 selectivity than many older NSAIDs.

For African Grey parrots, robenacoxib is not FDA-approved, so use in parrots is considered off-label or extra-label. That does not mean it is inappropriate. It means your vet is using available evidence, species experience, and your bird's condition to decide whether it is a reasonable option.

Avian data are still limited. Published pharmacokinetic work in parrots and avian formulary references suggest robenacoxib may be used in some psittacine birds, but dosing intervals and long-term safety are not as well defined as they are in dogs and cats. Because African Greys can hide illness until they are quite sick, your vet may recommend baseline bloodwork and close follow-up before and during treatment.

In parrot medicine, robenacoxib may be considered when your vet wants an NSAID option for pain linked to inflammation. Reported avian uses include arthritis, other orthopedic pain, pododermatitis, and supportive pain control around minor procedures. Some avian references also list use in birds with avian bornavirus-related disease or chronic inflammatory discomfort, although response can vary widely.

For an African Grey parrot, the goal is usually better comfort, easier movement, improved perching, and a more normal appetite and activity level. A bird with painful inflammation may spend less time climbing, avoid one foot, fluff more than usual, or seem reluctant to step up.

Robenacoxib is only one option. Depending on the problem, your vet may instead recommend another NSAID, a different pain medication, husbandry changes, weight support, perch changes, physical rehabilitation, or diagnostics first. The best plan depends on whether the pain is acute, chronic, infectious, traumatic, or related to a deeper disease process.

Never dose robenacoxib in an African Grey parrot without your vet's instructions. Avian dosing is individualized and usually based on your bird's exact body weight in grams, hydration status, kidney and liver health, and the reason the medication is being used.

Published avian references report anecdotal dosing ranges of 2-10 mg/kg every 3-7 days in birds, and the Merck Veterinary Manual lists 2-10 mg/kg IM weekly for 4 weeks, then monthly for selected avian conditions such as arthritis or avian bornavirus-related disease. A 2024 pharmacokinetic study in Hispaniolan Amazon parrots found a single 4 mg/kg oral dose was well tolerated in healthy birds, but the authors also noted that more pharmacodynamic work is still needed before firm psittacine dosing recommendations can be made.

That matters because African Grey parrots are not small dogs or cats. Tablet splitting can be inaccurate in birds, and compounded liquids may be needed for safer measurement. Your vet may choose oral dosing, an in-hospital injection, or a different medication entirely based on how reliable home dosing will be.

If your bird misses a dose, do not double the next one unless your vet specifically tells you to. Contact your vet for instructions. If your African Grey stops eating, vomits, seems weak, or becomes unusually quiet while taking robenacoxib, stop the medication and call your vet right away.

Like other NSAIDs, robenacoxib can cause digestive, kidney, liver, or bleeding-related side effects, especially in birds that are dehydrated, already ill, or taking interacting medications. Because parrots often show subtle signs first, pet parents may notice only a mild drop in appetite, quieter behavior, or less interest in climbing before more serious problems appear.

Possible side effects to watch for include decreased appetite, vomiting or regurgitation, diarrhea, dark or tarry droppings, lethargy, weakness, increased fluffing, reduced activity, or worsening balance on the perch. In a bird, any sign of gastrointestinal bleeding, collapse, or major appetite loss is urgent.

Your vet may be more cautious or avoid robenacoxib in birds with dehydration, kidney disease, liver disease, gastrointestinal ulcer risk, bleeding disorders, or a history of NSAID sensitivity. Monitoring is especially important if treatment will continue beyond a brief course.

See your vet immediately if your African Grey parrot has black droppings, repeated vomiting, marked weakness, trouble perching, seizures, or stops eating. Birds can decline quickly, and early intervention matters.

The most important interaction rule is this: robenacoxib should not usually be combined with another NSAID or with corticosteroids unless your vet specifically directs it. That includes medications such as meloxicam, aspirin, carprofen, prednisone, dexamethasone, and similar anti-inflammatory drugs. Combining them can raise the risk of stomach or intestinal injury, kidney stress, and bleeding.

Your vet also needs to know about any medication or supplement your bird receives, including compounded drugs, liver support products, herbal products, and over-the-counter items. In other species, caution is advised with drugs that may affect the kidneys, hydration, clotting, or gastrointestinal lining. Examples include diuretics such as furosemide, cyclosporine, and some drugs associated with bleeding risk.

Because African Grey parrots often receive complex care plans, interaction review is especially important when a bird is also being treated for chronic disease, infection, neurologic signs, or gastrointestinal problems. Bring a full medication list to every visit, including exact strengths and how often you give each product.
