Docosanol
Docosanol (pronunciation: doh-KOH-sah-nol) is an antiviral medication used topically to treat and prevent recurring cold sores due to the herpes simplex virus. It is also known by the brand name Abreva.
Etymology
The term "Docosanol" is derived from the Greek words "dokos" meaning "long" and "anol" referring to the chemical structure of alcohols.
Usage
Docosanol is applied topically to the affected area at the first sign of a cold sore (such as tingling, redness, bump, or itch). It is typically used five times a day until the sore is fully healed.
Mechanism of Action
Docosanol works by inhibiting the fusion of the human host cell with the viral envelope of the herpes simplex virus, thus preventing the virus from entering the cell and multiplying.
Side Effects
Common side effects of Docosanol may include skin irritation or rash. If these effects persist or worsen, medical attention should be sought.
