The empirical formula for acetic acid is CH3 COOH, with a molecular weight of 60.05. The structural formula is:
Acetic Acid is available as a nonaqueous otic solution buffered at pH 3 for use in the external ear canal.
Acetic acid is antibacterial and antifungal; propylene glycol is hydrophilic and provides a low surface tension; benzethonium chloride is a surface active agent that promotes contact of the solution with tissues.
For the treatment of superficial infections of the external auditory canal caused by organisms susceptible to the action of the antimicrobial.
Hypersensitivity to acetic acid or any of the ingredients. Perforated tympanic membrane is considered a contraindication to the use of any medication in the external ear canal.
Discontinue promptly if sensitization or irritation occurs.
Transient stinging or burning may be noted occasionally when the solution is first instilled into the acutely inflamed ear.
Safety and effectiveness in pediatric patients below the age of 3 years have not been established.
Stinging or burning may be noted occasionally; local irritation has occurred very rarely.
Carefully remove all cerumen and debris to allow acetic acid to contact infected surfaces directly. To promote continuous contact, insert a wick of cotton saturated with acetic acid 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 to 5 drops of acetic acid every 4 to 6 hours. The wick may be removed after 24 hours but the patient should continue to instill 5 drops of acetic acid 3 or 4 times daily thereafter, for as long as indicated. In pediatric patients, 3 to 4 drops may be sufficient due to the smaller capacity of the ear canal.
