Acyclovir fights the herpes virus by entering infected cells and stopping the virus from copying itself. It is only active in infected cells because the virus produces an enzyme that activates acyclovir. This makes it effective in reducing the virus’s ability to spread and cause symptoms.

Pregnancy and breastfeeding: - Limited data suggest acyclovir is safe during pregnancy, but it should be used cautiously.
