Herpex Cream 5gm (Acyclovir Cream 5%) | Zovirax Cream | Used to Treat Genital Herpes & Cold Sores
Herpex Cream 5gm (Acyclovir 5%) is used to treat viral infections of skin, mucus membrane and genitals caused by herpes simplex virus including shingles such as cold sores and genital herpes. Acyclovir can also be used to treat chickenpox (also viral infections).
Product Overview
Herpex Cream 5gm is an antiviral treatment containing 5 percent Acyclovir, to manage infections caused by the herpes simplex virus. This cream is widely used to address localized outbreaks, including cold sores (herpes labialis). By inhibiting the replication of the virus, the cream works to accelerate the healing of lesions, reduce the duration of symptoms such as tingling, pain, and burning, and limit the severity of the outbreak. Herpex Cream is designed for rapid absorption into the skin, providing a focused defense at the site of infection. Consistent and early application is essential to maximize the therapeutic benefits, helping to shorten the recovery time and prevent the progression of sores.

Mechanism of Action
- Acyclovir acts as a selective inhibitor of the herpes simplex virus DNA polymerase
- Once absorbed into the skin, the active ingredient is converted into its active form within the infected cells
- It effectively terminates the viral DNA chain, preventing the virus from multiplying and spreading to adjacent healthy cells
- This targeted intervention reduces the viral load, allowing the body natural immune response to heal the affected tissue more efficiently
Key Benefits
- Reduces the duration of healing for cold sores and similar herpes simplex outbreaks
- Provides relief from discomforting symptoms like pain, burning, and tingling at the site
- Helps to prevent the further spread of the viral infection if applied at the earliest signs
- Concentrated formula ensures effective delivery of the antiviral agent to the site of the lesion
- Promotes a faster return to normal skin health with regular application
