Herperax

Herperax contains Acyclovir, an antiviral medication. It works by selectively inhibiting viral DNA synthesis, thereby stopping the replication and spread of the herpes simplex and varicella-zoster viruses in the body. While it helps speed up healing and reduces pain, it is not a permanent cure for herpes infections.
