Ivermectin 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.

Ivermectin is a prescription antiparasitic medication in the avermectin family. In birds, your vet may use it extra-label, which means the drug is being used in a species, dose, or route not specifically listed on the product label but allowed under veterinary supervision. That matters in African Grey parrots because small dosing errors can become serious very quickly.

This medication works by disrupting nerve and muscle function in susceptible parasites. In practical terms, it is most often chosen when your vet is concerned about certain mites or nematodes (roundworms) rather than bacterial, fungal, or viral disease. It is not a general wellness medication, and it is not appropriate for every itchy, feather-damaging, or breathing-related problem.

For parrots, ivermectin may be given by mouth, by injection, or sometimes in a carefully measured compounded form depending on the parasite involved and your bird's size, condition, and handling tolerance. African Greys often need a very individualized plan because body weight, hydration, liver function, and stress level can all affect how safely a medication is used.

In pet birds, ivermectin is most commonly used for mite infestations and some roundworm infections. Merck Veterinary Manual lists ivermectin as a treatment option for scaly face or leg mites, feather mites, and certain roundworms in pet birds. It is also used for air sac mites in species where those parasites are a concern, though air sac mites are much more common in finches and canaries than in African Grey parrots.

For African Greys, the biggest point is that ivermectin should only be used when your vet has a reason to suspect or confirm a parasite problem. Feather picking, poor feather quality, weight loss, noisy breathing, and skin irritation can have many causes besides parasites, including nutrition, behavior, infection, organ disease, and environmental stress. Treating without a diagnosis can delay the right care.

Your vet may pair ivermectin with other steps such as fecal testing, skin or feather evaluation, cage sanitation, nest box replacement, and treatment of in-contact birds when appropriate. Medication alone may not solve the problem if the environment is still contaminated or if the original diagnosis was incorrect.

Never calculate an ivermectin dose for your African Grey at home unless your vet has given you exact instructions for that specific bird and that exact formulation. Bird doses are tiny, and concentrated livestock products can cause dangerous overdoses if they are measured incorrectly.

Published avian references commonly list ivermectin at 0.2 mg/kg by mouth, intramuscular injection, or sometimes subcutaneous injection for several pet-bird parasite problems, usually with a repeat dose in about 10 to 14 days or 2 weeks depending on the parasite. Merck Veterinary Manual also lists 0.2 to 0.4 mg/kg for air sac mites, repeated in 2 weeks. Those are reference ranges, not a home-treatment recipe.

Your vet may adjust the plan based on your parrot's weight, hydration, parasite type, route of administration, and whether a compounded dilution is needed for safer measuring. In many parrots, the repeat treatment is important because ivermectin may not reliably eliminate every life stage with one dose alone. If your bird spits out medication, vomits, or seems weaker after dosing, contact your vet right away before giving another dose.

Many birds tolerate ivermectin well when it is prescribed and dosed carefully, but side effects can happen. Mild concerns may include temporary decreased appetite, quiet behavior, or stress related to handling. More serious problems are usually linked to overdose, incorrect concentration, or use in a bird that is already medically fragile.

Call your vet promptly if you notice weakness, wobbliness, falling from the perch, marked sleepiness, tremors, vomiting or regurgitation, trouble breathing, or seizures after treatment. These signs can suggest neurologic toxicity or another urgent reaction. Because African Grey parrots can hide illness until they are quite sick, even subtle changes after a new medication deserve attention.

If you think your parrot received too much ivermectin, see your vet immediately. Bring the bottle, label, concentration, and the exact amount given if you can. Fast action helps your vet decide whether your bird needs supportive care, warming, fluids, oxygen support, crop feeding, or hospitalization.

Published bird-specific interaction data are limited, so your vet will usually review all medications, supplements, and topical products before prescribing ivermectin. This is especially important in parrots already being treated for respiratory disease, liver disease, fungal infections, or chronic pain, because a sick bird may have less margin for dosing error.

In general veterinary medicine, ivermectin is used cautiously with other drugs that can affect the nervous system or alter drug transport across the blood-brain barrier. Your vet may also be more careful if your African Grey is receiving multiple antiparasitic products at the same time, or if a topical mite treatment is being used alongside oral or injectable therapy.

You can help by bringing a full list of everything your bird gets, including compounded medications, over-the-counter products, supplements, and any farm-store parasite products in the home. Never substitute a livestock ivermectin product, dog dewormer, or another pet's medication for your parrot's prescribed formulation.
