1. WHAT BLISTEX COLD SORE CREAM IS AND WHAT IT IS USED FOR

Docosanol is an antiviral agent. Blistex Cold Sore Cream is a white cream used for the treatment of early stages of recurrent labial herpes simplex infection (cold sores) in adults and adolescents (over 12 years old).

To be effective, treatment with Blistex Cold Sore Cream must start in the early stages of a cold sore before the blisters appear. Start using Blistex Cold Sore Cream as soon as you get any of the symptoms of a cold sore such as redness, itching, pain, tingling or prickling. Continue using until the cold sore is healed, usually 4-6 days.

The cause of cold sores is a herpes simplex virus infection. The infection may break out when the immune system is weakened, during stress or during a menstrual period. The virus causes blisters or sores, mainly on the lips.
