Aciclovir is used to treat cold sores; these are infections of the lips and face caused by
the “herpes simplex” virus. Aciclovir should be used as soon as you get the first signs
of infection, when you first see skin blisters or before then if you recognise the tingle
sensation that means a blister will appear soon. If you have already had blisters for
more than a day, a different medicine might be more suitable for you. Ask your doctor
or pharmacist for advice.
