See the DrugPatentWatch profile for Abreva
The active ingredient in Abreva is docosanol [1].
What is Docosanol Used For?
Docosanol is an antiviral medication [2]. It is specifically used to treat cold sores, also known as fever blisters, which are caused by the herpes simplex virus [3].
How Does Docosanol Work to Treat Cold Sores?
Docosanol works by inhibiting the ability of the herpes simplex virus to enter healthy cells [4]. It is believed to disrupt the formation of the viral envelope, thereby preventing the virus from replicating and spreading [4].
What is the Difference Between Abreva and Other Cold Sore Treatments?
Abreva's active ingredient, docosanol, is unique among over-the-counter cold sore treatments because it works by physically blocking the virus from entering healthy cells [4]. Many other treatments focus on masking symptoms or providing temporary relief [5].
How Quickly Does Abreva Start Working?
When applied at the first sign of a cold sore, Abreva can help shorten the healing time [3]. It is most effective when used early in the outbreak [3].
