Acyclovir works by interfering with the replication of viral DNA. It binds to a specific enzyme, known as DNA polymerase, which is responsible for the replication of viral DNA. By binding to the enzyme, acyclovir prevents the replication of viral DNA and thus stops the virus from spreading. Acyclovir is effective against HSV-1, HSV-2, VZV, and EBV.
