Acetic Acid Drug Information

For the treatment of superficial infections of the external auditory canal caused by organisms susceptible to the action of the antimicrobial.

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.

Stinging or burning may be noted occasionally; local irritation has occurred very rarely. To report SUSPECTED ADVERSE REACTIONS, contact Saptalis Pharmaceuticals, LLC at 1-833-727-8254 or FDA at 1­800-FDA-1088 or www.fda.gov/medwatch.

Safety and effectiveness in pediatric patients below the age of 3 years have not been established.

Hypersensitivity to acetic acid otic solution or any of the ingredients. Perforated tympanic membrane is considered a contraindication to the use of any medication in the external ear canal.
