What famciclovir is used for
It is used to manage outbreaks of herpes zoster, herpes simplex and genital herpes. Treatment eases the outbreak; it does not clear the virus from the body. The medicine sits within the antivirals class.
How it works
After a dose, famciclovir is converted to penciclovir. Penciclovir inhibits viral DNA polymerase, interrupting viral DNA synthesis and replication. With the virus unable to multiply freely, the body has a better chance to manage the infection.
