How should avermectin ointment be used for ear mites? - briefly
Apply a thin layer of avermectin ointment directly into the ear canal, gently massage the base of the ear to spread the medication, and ensure the animal’s head is held upright for a few minutes to allow absorption. Follow the veterinarian’s recommended schedule, usually once daily for three to five consecutive days.
How should avermectin ointment be used for ear mites? - in detail
Veterinary guidelines recommend a systematic approach when treating ear mite infestations with an avermectin-based ointment. The procedure includes preparation, application, and follow‑up.
Before treatment, inspect the ear canal for excessive wax, debris, or signs of secondary infection. If thick cerumen is present, clean the ear gently with a veterinarian‑approved solution and a soft gauze pad. Allow the ear to dry completely; residual moisture can dilute the medication and reduce efficacy.
Apply the ointment as follows:
- Dosage determination – Calculate the amount based on the animal’s species, weight, and the concentration indicated on the product label. Typical recommendations range from 0.5 g to 1.0 g for small dogs and cats, with adjustments for larger breeds.
- Administration technique – Lift the ear flap to expose the canal. Squeeze the measured dose into the vertical portion of the ear, aiming for the deepest reachable point without forcing the tip. Avoid direct contact with the skin to prevent irritation.
- Frequency – Initial dose is administered once. A repeat application is usually required after 7 days to eliminate newly hatched mites. Some protocols advise a third dose at day 14 for severe infestations.
- Post‑application care – Keep the animal from scratching the treated ear for at least 30 minutes. Monitor for excessive rubbing or signs of discomfort; if observed, consult a veterinarian promptly.
Safety considerations:
- Do not use in animals with known hypersensitivity to avermectins.
- Avoid administration to pregnant or lactating females unless explicitly approved.
- Keep the product out of reach of children and other pets; accidental ingestion can cause neurotoxicity.
- Store the ointment in a cool, dry place, away from direct sunlight, and respect the expiration date.
Follow‑up evaluation should occur 7 days after the final dose. Re‑examine the ear canal for residual debris, inflammation, or live mites using an otoscopic lens. If mites persist, a longer treatment course or alternative acaricide may be necessary. Document all observations and adjust the protocol based on the animal’s response.
