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.[3]

United states ban on manufacture

In 2015, in accordance with their initiative to remove unapproved prescription drugs from the market, the FDA mandated that companies stop manufacturing this drug or be subject to criminal charges. The FDA has not evaluated this drug for safety, effectiveness or quality and has concerns about inappropriate dosing and risk of contamination during the manufacturing process. [4] The FDA adverse event reporting database does not have any known cases of adverse events where Auralgan is the primary suspect. [5]
