A GUANOSINE analog that acts as an antimetabolite. Viruses are especially susceptible. Used especially against herpes.
Acyclovir is used to treat infections caused by certain types of viruses. It treats cold sores around the mouth (caused by herpes simplex), shingles (caused by herpes zoster), and chickenpox.
