The recommended adult dose of valacyclovir to treat shingles is 1,000 mg 3 times daily for 7 days. The treatment should be started within 72 hours of the onset of the rash.

To treat the first episode of genital herpes, the dose of valacyclovir is 1,000 mg twice daily for 10 days. Treatment should be started within 72 hours of the onset of symptoms, and ideally within 48 hours for best effectiveness.

To treat recurrent genital herpes, the dose of valacyclovir is 500 mg twice daily for 3 days. The treatment should be started at the first sign or symptom of recurrence.

To prevent recurrences of genital herpes, the recommended dose is 1,000 mg once daily. For people with a history of 9 or fewer recurrences per year, the recommended dosage of valacyclovir is 500 mg orally once daily. This dose helps to reduce the risk of transmitting genital herpes to others.

To treat cold sores, the usual dose of valacyclovir is 2,000 mg at the first sign of symptoms, followed by another 2,000 mg 12 hours later. The treatment should be started at the first sign of a cold sore (tingling, itching, or burning sensations) for best effectiveness.

Immunosuppression (weak immune system): People who have a weakened immune system should only use valacyclovir if the benefits outweigh the risks. If you have had an organ transplant, are infected with HIV, or otherwise have a weak immune system, discuss with your doctor how Teva Valacyclovir may affect your medical condition, how your medical condition may affect the dosing and effectiveness of Teva Valacyclovir, and whether any special monitoring is needed.

Safer sex: Valacyclovir, when taken in appropriate doses each day, can reduce the risk of passing genital herpes to sexual partners. It should be used in combination with safer sex practices such as using condoms and dental dams. If you have any questions about practicing safer sex, speak to your doctor.

Systemic infection: The safety and effectiveness of using valacyclovir to treat herpes zoster infection that is inside the body has not been established. This is not an accepted use for Teva Valacyclovir.
