What is administered into a cat's ears for ear tick treatment? - briefly
A veterinary‑prescribed acaricidal ear drop—typically formulated with fipronil, selamectin, or ivermectin—is placed directly into the cat’s ear canal to eradicate ticks. The medication is applied according to the product’s dosage instructions and allowed to absorb for several minutes.
What is administered into a cat's ears for ear tick treatment? - in detail
Ear tick infestations in felines require a medicated solution applied directly into the external auditory canal. The most widely used products are liquid acaricidal ear drops that contain one or more active ingredients such as ivermectin, selamectin, fipronil, or a combination of pyrethrins and organophosphates. These agents act by disrupting the nervous system of the parasite, leading to rapid paralysis and death.
Before administration, the ear should be examined and any debris, wax, or discharge removed with a cotton ball or gauze. The canal is then gently dried to improve contact between the medication and the tick. The recommended dose is measured with the dropper supplied by the manufacturer, typically ranging from 0.2 ml to 0.5 ml per ear, depending on the cat’s weight and the product’s concentration. The solution is instilled by holding the cat’s head upright, pulling the ear flap back to expose the canal, and delivering the measured drops directly onto the affected area. After dosing, the cat’s head is held for a few seconds to allow the liquid to spread, and the ear is massaged lightly to ensure even distribution.
Key considerations include:
- Prescription status: Most effective acaricidal ear drops are available only with a veterinary prescription.
- Species specificity: Formulations approved for cats differ from those for dogs; using a canine product can cause severe toxicity.
- Frequency: Treatment protocols vary; some products require a single application, while others call for repeated dosing every 7–14 days until the infestation resolves.
- Safety margins: Common adverse effects are transient irritation, redness, or increased ear scratching. Severe reactions such as swelling, ulceration, or systemic signs (vomiting, lethargy) warrant immediate veterinary attention.
- Adjunct care: In cases of secondary bacterial or fungal infection, a veterinarian may prescribe an antimicrobial ear cleanser or ointment to be used before the acaricide.
Proper administration, adherence to the prescribed schedule, and monitoring for side effects are essential for eliminating ear ticks and preventing recurrence.
