Dosage And Administration
Carefully remove all cerumen and debris to allow acetic acid otic solution to contact infected surfaces directly. To promote continuous contact, insert a wick of cotton saturated with acetic acid otic solution into the ear canal; the wick may also be saturated after insertion. Instruct the patient to keep the wick in for at least 24 hours and to keep it moist by adding 3 drops to 5 drops of acetic acid otic solution every 4 hours to 6 hours. The wick may be removed after 24 hours but the patient should continue to instill 5 drops of acetic acid otic solution 3 times or 4 times daily thereafter, for as long as indicated. In pediatric patients, 3 drops to 4 drops may be sufficient due to the smaller capacity of the ear canal.
Acetic acid otic solution, USP, containing 2% acetic acid, is available in 15 mL measured‑drop, safety-tip plastic bottles.
