Aciclovir tablets are used as an antiviral medication primarily for the treatment of infections caused by herpes viruses. This includes herpes simplex virus infections such as genital herpes (both initial and recurrent), cold sores (herpes labialis), chickenpox, and shingles (herpes zoster). It can also be used to prevent herpes simplex infections in immunocompromised patients and for other herpes-related conditions like herpes of the eye and herpes simplex encephalitis. Aciclovir works by inhibiting viral DNA replication, thereby reducing the production and spread of the virus in the body. It does not cure herpes but helps to lessen symptoms and speed up healing.

How It Works
Aciclovir is a nucleoside analogue that mimics guanosine, which interferes with the virus's DNA replication process, thereby reducing the spread and severity of infection.
