Ivermectin for Conures: 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 macrocyclic lactone family. In birds, your vet may use it extra-label, which means it is prescribed based on veterinary judgment rather than a bird-specific FDA label. That is common in avian medicine, but it also means dosing has to be tailored carefully to the individual bird.

In conures, ivermectin is most often discussed for mite problems, not as a routine medication. It works by interfering with nerve and muscle function in susceptible parasites, which can paralyze and kill certain mites and worms. Because conures are small and sensitive, even a tiny measuring error can matter.

This is not a medication to start at home from livestock products or internet dosing charts. Concentrations vary widely between products, and bird-safe dosing often requires very small volumes or dilution by your vet or pharmacist. If your conure has itching, crusting around the beak, breathing noise, or feather damage, your vet will first try to confirm whether parasites are actually the cause.

In pet birds, ivermectin is commonly used for scaly face or leg mites, feather mites, and in some cases air sac mites. Merck Veterinary Manual notes ivermectin can be effective for scaly face mites at 0.2 mg/kg by mouth or intramuscularly, repeated in 2 weeks, and for air sac mites at 0.2-0.4 mg/kg, also repeated in 2 weeks. Those are broad avian references, not a substitute for an individualized conure plan.

For conures specifically, your vet may consider ivermectin when there is evidence of parasitic disease such as crusting around the cere or beak, feather irritation linked to mites, or respiratory signs that raise concern for air sac mites. Still, parasites are not the most common reason a conure scratches, loses feathers, or breathes abnormally. Nutrition issues, infection, liver disease, environmental irritation, and behavior can look similar.

That is why diagnosis matters. Your vet may recommend an exam, skin or feather evaluation, fecal testing, or imaging before treatment. In some cases, your vet may choose a different antiparasitic such as moxidectin, or may focus on cage sanitation and treating in-contact birds if the problem is contagious.

Ivermectin dosing in birds is weight-based and should be set by your vet. Published avian references commonly list 0.2 mg/kg for scaly face and feather mites, and 0.2-0.4 mg/kg for air sac mites, usually repeated in about 2 weeks. The exact route may be oral, injectable, or sometimes topical depending on the case, the product concentration, and your vet's comfort with avian dosing.

For a conure, the challenge is not only the dose in mg/kg. It is also the product concentration. Livestock ivermectin products can be far too concentrated for a small bird, so a dose that looks tiny on paper can become dangerous if the wrong formulation is used. Your vet may have the medication compounded or diluted to make accurate dosing safer.

Never redose early because signs are still present, and never assume one bird's dose fits another conure. Age, body weight, hydration, liver health, severity of infestation, and whether other birds in the home are affected can all change the plan. If you miss a dose, call your vet before giving more.

Most birds tolerate correctly prescribed ivermectin reasonably well, but side effects can happen. Mild problems may include temporary lethargy, reduced appetite, loose droppings, or stress from handling. Some birds also seem quieter than usual for a short period after treatment.

The more serious concern is toxicity, especially if the wrong concentration is used or too much is given. Signs can include weakness, poor coordination, tremors, inability to perch, marked depression, collapse, or seizures. Merck notes that parasiticide overdose can cause neurologic signs in exotic species, and poultry references list a toxic ivermectin dose far above treatment levels, underscoring that safety depends on staying within a narrow, accurate range.

See your vet immediately if your conure becomes very sleepy, stops eating, falls off the perch, has trouble breathing, or shows any neurologic change after ivermectin. Small birds can decline quickly, so same-day guidance matters.

Published bird-specific interaction data are limited, so your vet will usually take a cautious approach. In general, ivermectin should be used carefully with other medications that may affect the nervous system, and with any drug plan in a bird that is already weak, dehydrated, or medically unstable.

Because ivermectin is often used extra-label in birds, your vet may also review whether your conure is receiving other antiparasitics, recent topical sprays or powders, antifungals, or compounded medications. Combining treatments without a clear plan can make side effects harder to interpret and may increase risk.

Tell your vet about everything your conure has had recently, including over-the-counter mite sprays, supplements, herbal products, and any medication intended for another pet. That helps your vet choose the safest option and decide whether ivermectin, moxidectin, environmental treatment, or watchful follow-up makes the most sense.
