Description
Valcivir-500 Tablet is an antiviral medicine. It is used in the treatment of infections caused by herpes viruses, including genital herpes (a sexually transmitted infection), cold sores (small painful blisters around the mouth or other areas of the face), and shingles (viral infection that causes painful rashes or blisters on the skin).

Valcivir-500 Tablet is available on prescription as a tablet form. Take it with or without food in the dose and duration prescribed by your doctor. Take this medicine at the same time every day to maintain a constant level in your blood. Do not take more than the prescribed dose. Complete the treatment even if you feel better after taking a few doses. Avoid sudden discontinuation of this medicine as it may lead to a relapse of the infection.
