Acyclovir

Acyclovir is an antiviral medication used to treat infections caused by herpes viruses, including herpes simplex (cold sores and genital herpes), varicella (chickenpox), and herpes zoster (shingles). It works by slowing the growth and spread of the virus, helping to reduce symptoms and speed up healing. While Acyclovir does not cure viral infections, it helps control outbreaks and reduces the risk of complications. It is available in tablet, capsule, cream, and injection forms, and should be used as prescribed by a doctor.

Uses of Acyclovir

• Treats herpes simplex virus (HSV) infections

• Used for chickenpox treatment

How Acyclovir Works

Acyclovir interferes with the replication of viral DNA, stopping the virus from multiplying in the body. It is converted into its active form inside infected cells, where it blocks viral enzyme activity. This slows down virus reproduction, helping to control symptoms and speed up recovery.
