Zovirax is used for the treatment of Herpes Simplex. Aciclovir (the active ingredient of Zovirax) belongs to a group of medicines called 'anti-virals'. Zovirax works by stopping the production of the herpes virus. This reduces the length and severity of an outbreak of herpes. Zovirax can also be taken long term to reduce the number of herpes outbreaks in people who experience this condition often. Zovirax does not get rid of the virus from your body.

When to cease treatment

Do not stop taking Zovirax just because you feel better. It is important that you complete your course of tablets to effectively treat an outbreak of herpes (generally 5 days).
