A/B otic drops is indicated for ear pain caused by otitis media. It is used every 2–3 hours as needed for pain.

A/B otic drops is also indicated for the removal of excessive or impacted cerumen. To clear cerumen, it is used 3 times a day for 2–3 days.

Clinical pharmacology
A/B otic drops are effective because antipyrine reduces pain and inflammation and benzocaine numbs the ear.

Reformulation
In 2008, Auralgan was reformulated to include acetic acid and U-polycosanol 410, in addition to antipyrine and benzocaine. Due to this reformulation, pharmacies could no longer substitute the generic antipyrine/benzocaine drops for a prescription written as "Auralgan". The price for the new formulation was roughly $150.00 compared to the generic price of $2.00.
