(Back to top) VALACYCLOVIR (Valtrex®) is an antiviral agent. Valacyclovir treats herpes zoster infection (shingles) or genital herpes infection. Valacyclovir is not a cure; it will help the sores heal faster and relieve the pain or discomfort. Valacyclovir can also be used to help prevent a genital herpes infection from coming back. Valacyclovir might help prevent genital herpes from being passed on to a partner who does not have genital herpes if it is used with 'safer sex' practices. Generic valacyclovir caplets are not yet available. What should I tell my health care provider before I take this medicine?

Valacyclovir works best when taken early in the course of an infection, preferably within the first 72 hours. Begin treatment as soon as possible after the first signs of infection (such as tingling, itching, or pain in the affected area). Valacyclovir may be helpful in preventing the spread of infection to others. Valacyclovir will only help prevent the spread of genital herpes if you use 'safer sex' practices.
