Zovirax

Aciclovir is taken by mouth to treat herpes infections that cause chickenpox and shingles. It is also taken by mouth to treat genital herpes and other herpes simplex infections of the skin and mucous membranes, and to prevent these infections coming back in people who suffer recurrent infections. Oral aciclovir is also valuable for preventing herpes simplex infections in people whose immune systems are supressed and cannot fight off infection, either due to disease, eg HIV and AIDS, or medical treatment, eg chemotherapy, steroids, bone marrow transplant.
