Abreva

Abreva is an antiviral, over the counter cold sore drug. Marketed as Erazaban in Europe, it was the first antiviral drug that was approved for sale in the USA and Canada over the counter. The key ingredient is behenyl alcohol; a fatty alcohol used as an antiviral agent, for the treatment of cold sores caused by the herpes simplex virus. Clinical trials by the FDA, have shown behenyl alcohol to shorten the healing time of a cold sore by 17.5 hours. While 10% of Abreva is made up of behenyl alcohol, the remaining 90% is a base mix.
