Hydrocortisone and Acetic Acid - Clinical Pharmacology
Acetic acid is anti-bacterial and anti-fungal; hydrocortisone is anti-inflammatory, anti-allergic and anti-pruritic; 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.
Indications and Usage for Hydrocortisone and Acetic Acid
For the treatment of superficial infections of the external auditory canal caused by organisms susceptible to the action of the antimicrobial, complicated by inflammation.
Hypersensitivity to any of the ingredients, herpes simplex, vaccinia and varicella. 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.
Hydrocortisone and Acetic Acid Dosage and Administration
Carefully remove all cerumen and debris to allow solution to contact infected surfaces directly. To promote continuous contact, insert a wick of cotton saturated with the 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 to 5 drops of solution every 4 to 6 hours. The wick may be removed after 24 hours but the patient should continue to instill 5 drops of solution 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.

Store at 20° to 25°C (68° to 77°F) [See USP Controlled Room Temperature].
