Herpex 5% Cream – Uses, Composition, Dosage

Herpex 5% Cream is a topical antiviral medication containing Acyclovir 5% w/w. It is used for treating skin and mucocutaneous infections caused by the Herpes simplex virus, such as cold sores (herpes labialis) and genital herpes. When applied early, it helps to shorten the duration of outbreaks, reduce pain, itching, burning, and the number of new lesions. It does not cure herpes permanently but helps in managing symptoms and speeding recovery.

✅ Uses of Herpex 5% Cream

• Treats cold sores (herpes labialis) around the lips or on the face.

• Manages genital herpes outbreaks.

• Useful for herpetic skin lesions and herpes zoster when mild.

💊 Composition

• Active Salt: Acyclovir (5% w/w)

• In a cream base with appropriate stabilizers/excipients.

⚙️ How It Works (Mechanism of Action)

Acyclovir works by selectively inhibiting the viral DNA polymerase enzyme in infected cells. It is first activated by a viral enzyme (thymidine kinase), and then further by other cellular enzymes. The active form blocks replication of viral DNA, stopping the virus from multiplying and allowing the body’s immune system to help clear the infection.
