Aciclovir, also known as acyclovir, is an antiviral medication. It is primarily used for the treatment of herpes simplex virus infections, chickenpox, and shingles. Other uses include the prevention of cytomegalovirus infections following transplant, and severe complications of Epstein–Barr virus infection. It can be taken by mouth, applied as a cream, or injected.

Recurrent moderate to severe genital herpes Clinical criteria: Treatment Phase: Episodic treatment or suppressive therapy Microbiological confirmation of diagnosis [viral culture, antigen detection or nucleic acid amplification by polymerase chain reaction (PCR)] is desirable but need not delay treatment.
Herpes zoster Clinical criteria: The treatment must be administered within 72 hours of the onset of the rash.
“Aciclovir is converted by viral thymidine kinase to aciclovir monophosphate, which is then converted by host cell kinases to aciclovir triphosphate (ACV-TP, also known as aciclo-GTP). ACV-TP is a very potent inhibitor of viral DNA replication. ACV-TP competitively inhibits and inactivates the viral DNA polymerase. Its monophosphate form also incorporates into the viral DNA, resulting in chain termination.”
