What Aciclovir GH is used for

Aciclovir GH contains aciclovir, a compound that belongs to a group of medicines called antivirals.

Aciclovir GH is used for the treatment of shingles (herpes zoster), impaired immunity and genital herpes.

In the case of shingles, Aciclovir GH 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, Aciclovir GH also guards against the herpes virus disease. Aciclovir does not get rid of the virus from your body.

Your doctor may have prescribed Aciclovir GH for another purpose.

Aciclovir GH 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 Aciclovir GH has been prescribed for you.

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

How to take it

Take Aciclovir GH exactly as your doctor has prescribed.

Follow all directions given to you by your doctor or pharmacist. They may differ from the information contained in this leaflet.

How long to take it

You must take Aciclovir GH for as long as your doctor tells you. Do not stop taking Aciclovir GH just because you feel better.

If you forget to take it

If you forget to take a dose, take one as soon as you remember, unless this is within an hour of when the next dose is due. Then go on as before.
