Acyclovir Capsules

Description

Generic Name: Acyclovir
Brand Names: Zovirax
Important Warning
Acyclovir tablets and capsules are antiviral medications used to treat infections caused by herpes viruses, including genital herpes, cold sores, shingles (herpes zoster), and chickenpox (varicella). These medications do not cure herpes infections but can reduce symptoms and speed up healing.

Acyclovir is most effective when started at the earliest sign of an outbreak (e.g., tingling, itching, or burning before lesions appear). Follow your doctor’s instructions carefully for the best results.

Uses for Acyclovir Tablets/Capsules
Acyclovir is prescribed for:

Treating herpes simplex infections, including genital herpes and cold sores.
Treating varicella (chickenpox) and herpes zoster (shingles).
Preventing recurrent outbreaks of genital herpes in patients with frequent recurrences.
Reducing the risk of herpes transmission in certain cases.
Acyclovir works by stopping the growth of the virus, although it does not eliminate the virus from the body.
