Who it is for

How to take it and how often
  • 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
