What OZVIR is used for
OZVIR contains aciclovir, a compound that belongs to a group of medicines called antivirals.
OZVIR is used for the treatment of shingles (herpes zoster), impaired immunity and genital herpes.
In the case of shingles, OZVIR works by stopping the multiplication of the virus which causes shingles. It can reduce the length and severity of an outbreak of shingles but it will not get rid of the virus from your body.
Aciclovir at high strength is used as part of the management program in people who have human immunodeficiency virus disease (HIV). It acts by preventing further damage to the immune system. In these people, OZVIR also guards against the herpes virus disease.
Aciclovir does not get rid of the virus from your body.
Your doctor may have prescribed OZVIR for another purpose.
OZVIR is not recommended for use in children as there have been no studies of its effects in children.
Ask your doctor if you have any questions about why OZVIR has been prescribed for you.
This medicine is only available with a doctor's prescription.

Do not take a double dose to make up for the dose that you missed. This may increase the chance of getting an unwanted side effect.
