ACICLOVIR SANDOZ is used for the treatment of genital herpes.

ACICLOVIR SANDOZ is used for the treatment of shingles (herpes zoster). Shingles is caused by the same virus that causes chicken pox.

If you have any questions about why you are taking ACICLOVIR SANDOZ ask your doctor or pharmacist.

ACICLOVIR SANDOZ contains the active ingredient aciclovir. Aciclovir belongs to a group of medicines called “anti-virals”.

ACICLOVIR SANDOZ works by stopping the multiplication of the virus that causes herpes. It can reduce the length and severity of an outbreak of herpes or alternatively may be used to reduce the number of outbreaks in someone who has frequent recurrences. It does not eliminate the herpes virus from the body.
