Celecoxib for Birds: Uses, Safety & 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 COX-2 inhibitor family. In birds, your vet may use it off-label, which means the medication is prescribed based on veterinary judgment rather than a bird-specific FDA approval. Avian dosing and response can vary by species, body weight, hydration status, and the reason the medication is being used.

This medication is used to help reduce pain and inflammation. It does not cure the underlying disease. In birds, celecoxib is most often discussed for arthritis and other painful inflammatory conditions, and it is also sometimes used as part of supportive care in birds with avian bornavirus-related disease or proventricular dilatation disease (PDD). Evidence in birds is limited, so your vet may recommend it only after weighing benefits, risks, and monitoring needs.

Because birds can hide illness until they are quite sick, celecoxib should never be started at home without veterinary guidance. Human medications can be dangerous in birds, even when the active ingredient is the same. Your vet may prescribe a compounded liquid so the dose can be measured accurately for a small patient.

Your vet may prescribe celecoxib when a bird needs help with mild to moderate pain, inflammation, or both. Common examples include osteoarthritis, chronic joint pain, soft tissue inflammation, and some painful mobility problems in older birds. In these situations, the goal is usually better comfort, easier movement, and improved daily function.

Celecoxib is also sometimes used in birds with avian bornavirus/PDD-related inflammation as part of a broader treatment plan. That said, published research has not shown clear improvement in mortality, viral shedding, or pathology in experimentally infected cockatiels treated with celecoxib. This matters because pet parents may hear about celecoxib online as a PDD medication, but it should be viewed as a possible supportive option, not a cure.

In some cases, your vet may choose celecoxib instead of another NSAID based on the bird's history, the suspected source of pain, prior response to medication, or ease of dosing. Treatment plans often work best when medication is paired with other supportive steps, such as weight management, perch changes, physical therapy guidance, or treatment of the underlying disease.

Celecoxib dosing in birds must be individualized by your vet. A commonly cited avian reference range is 10-30 mg/kg by mouth once daily to twice daily, but that does not mean every bird should receive that amount or schedule. In one controlled cockatiel study involving parrot bornavirus infection, birds received 10 mg/kg by mouth once daily. Your vet may choose a different plan based on species, diagnosis, age, hydration, kidney and liver status, and how long treatment is expected to continue.

Because many birds are very small, celecoxib is often dispensed as a compounded oral liquid. Accurate measuring matters. Even a small error can be significant in a cockatiel, budgie, conure, or lovebird. If your bird spits out medication, vomits, regurgitates, or seems stressed by dosing, tell your vet before adjusting anything on your own.

Follow your vet's instructions closely about timing, food, and rechecks. NSAIDs are often safest when the bird is well hydrated and monitored. Your vet may recommend baseline or follow-up testing in birds with chronic disease, dehydration risk, kidney concerns, liver concerns, or long-term NSAID use. Do not combine celecoxib with another pain reliever unless your vet specifically tells you to.

Side effects from celecoxib in birds can range from mild digestive upset to serious complications. The most important concern reported in avian literature is gastrointestinal bleeding. Watch droppings closely for black, tarry stool, fresh blood, darker-than-normal feces, or a sudden change in stool volume or appearance. If you see blood or your bird seems weak, fluffed, or less responsive, see your vet immediately.

More general NSAID risks include decreased appetite, vomiting or regurgitation, lethargy, behavior changes, increased or decreased drinking, changes in urination, and worsening weakness. As with other animals, NSAIDs can also affect the kidneys, liver, and stomach or intestines, especially if a bird is dehydrated, already ill, or receiving other interacting medications.

Some birds may develop hypersensitivity reactions. A published report described severe facial itching in a macaw that improved after celecoxib was stopped. Contact your vet promptly if you notice new itching, facial rubbing, swelling, sudden agitation, or skin changes. Stop the medication only under veterinary direction unless your bird is having an emergency reaction or signs of bleeding.

Celecoxib should be used carefully with other medications because drug combinations can raise the risk of side effects. The most important rule is that celecoxib should not usually be given with another NSAID or with a steroid unless your vet has a very specific reason and monitoring plan. Combining these drugs can increase the risk of stomach or intestinal injury and bleeding.

Tell your vet about every medication and supplement your bird receives, including over-the-counter products, pain relievers, herbal products, and anything borrowed from another pet. This is especially important if your bird is taking medications that may affect kidney perfusion, hydration, clotting, or the gastrointestinal tract.

Birds with kidney disease, liver disease, dehydration, poor appetite, active GI disease, or a prior NSAID reaction may need a different medication plan. If your bird is already on long-term treatment for avian bornavirus, arthritis, heart disease, seizures, or chronic infection, ask your vet to review the full medication list before celecoxib is started or refilled.
