About Herpival-1gm Tablet

Herpival-1gm Tablet contains a class of antiviral medication, valaciclovir, used to treat viral infections. It plays a vital role in treating cold sores (an inflamed blister in or near the mouth caused by infection with the herpes simplex virus), genital herpes (A common sexually transmitted infection marked by genital pain and sores), and herpes zoster (a viral infection that causes a painful rash). Herpival-1gm Tablet does not cure herpes but instead does not allow the infection to spread and treat its symptoms.

Herpival-1gm Tablet contains valacyclovir, which is an antiviral medication. Herpival-1gm Tablet is used in treating viral infection by preventing the multiplication of viruses in human cells. As a result, this stops the proliferation of viruses and produces new viruses, slowly leading to the viral infection clearing up.
