Zovirax Cream Uses
Zovirax cream uses are primarily concerned with treating cold sores. The medication has been approved for use in adults and adolescents who are at least 12 years old. Cold sores are caused by the herpes simplex virus, and Zovirax cream works by preventing the virus from multiplying. Some off-label Zovirax cream uses can include treating other viral skin infections.
An Overview of Zovirax Cream UsesZovirax® cream (acyclovir cream) is a prescription medication approved to treat cold sores in adults and adolescents age 12 and older.
This article refers to the cream form of Zovirax, which is different from the ointment form (see Zovirax Ointment).
Cold sores (known medically as herpes labialis) are caused by a virus, usually herpes simplex type 1 (HSV-1). Cold sores, also called fever blisters, usually occur on the lips or mouth (unlike canker sores, which occur inside the mouth). Cold sores can be highly contagious (they can spread to other people easily). Most people have been infected with this virus, even if they have never had a cold sore.
How Does Zovirax Cream Work?Cold sores are caused by viruses -- specifically, the herpes simplex viruses (HSV). Zovirax cream is an antiviral medication that helps the body fight the infection by preventing the virus from multiplying.
It is important to understand that once a person has been infected with these viruses, they never goes away. Rather, they remain inactive in certain nerve cells of the body, waiting to become active again. They can become active again at any time, often triggered by stress or illness. Treatment with Zovirax cream does not prevent future outbreaks of cold sores.
