What ZOVIRAX is used for
ZOVIRAX is used for the treatment and management of genital herpes.
How does ZOVIRAX work?
Aciclovir (the active ingredient in 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.
Your doctor may, however, have prescribed ZOVIRAX for a different use to that described above.
If you have any questions about why you are taking ZOVIRAX ask your doctor or pharmacist.
Your doctor or pharmacist will be able to provide you with more information.
