Acarexx (0.01% ivermectin) Otic Suspension is indicated for the treatment of adult ear mite (Otodectes cynotis) infestations in cats and kittens four weeks of age or older. Effectiveness against eggs and immature stages has not been proven.


Acarexx suspension is administered topically in the ear canal at an ivermectin concentration of 0.01%. One dose of 0.5 mL is applied in each ear. Repeat treatment one time if necessary, based upon the ear mite life cycle and the response to treatment.


In two Target Animal Safety studies, Acarexx suspension was proven to be safe in kittens four weeks of age or older. Four-week-old kittens were administered Acarexx suspension at dose rates of 1X, 3X and 5X the recommended dose for three or six consecutive days and no adverse reactions were observed, except one kitten treated at 1X the dose had histologic evidence of minimal, chronic dermal inflammation of the ear. In a well-controlled clinical field trial, Acarexx suspension was used safely in cats and kittens receiving other frequently used veterinary products such as flea control products, vaccines, anthelmintics, antibiotics and steroids.
