What Lovir is used for

Lovir tablets contain aciclovir, a compound that belongs to a group of medicines called antivirals. Lovir tablets are for the treatment of shingles (herpes zoster), impaired immunity and/or genital herpes.

In the case of shingles, Lovir 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 for certain infections in people who also have the human immunodeficiency virus. It acts by preventing further damage to the immune system as a result of stopping production of herpes viruses. Aciclovir does not get rid of the virus from your body.

Your doctor may have prescribed Lovir for another reason. If you are unsure why this medicine has been prescribed for you, speak to your doctor.

This medicine is only available with a doctor’s prescription.
