Valtrex is used to treat cold sores (herpes simplex) and shingles (Herpes Zoster). It is also used in to treat HIV-positive patients with genital herpes.
Valtrex comes in tablet form to be taken orally. The usual dose for shingles is three times a day, every eight hours, for one week. The dosage for genital herpes is twice a day for five days. For the treatment of cold sores, Valtrex is usually taken for one day only. For best results, treatment should begin as soon as symptoms appear. Do not discontinue the use of Valtrex without speaking to your doctor even if there is a significant improvement in your condition.
If a dose is missed, it can be taken as soon as you remember, as long as it does not clash with the next scheduled dose. In this case, rather skip the missed dose. Never take a double dose.
Herpes viruses are extremely contagious. Do not allow infected areas to come into contact with other people. Wash hands frequently to prevent contamination. Valtrex does not prevent the spread of genital herpes – it is therefore necessary to use a condom during sexual activity to prevent the spread of the virus.
