- Herpes labialis (cold sores);
- Herpes simplex genitalis (genital herpes);
- Herpes zoster (shingles);
Valtrex is prescribed to treat certain herpes infections, including herpes zoster (the painful rash known as shingles), genital herpes, and herpes cold sores on the face and lips.
Valtrex may be taken with or without
food. Dosages need to be reduced in patients with kidney disease. For the
treatment of herpes zoster (shingles), the usual dose is 1 gm three times a day
for 7 days. Treatment should begin at the first symptom and is most effective if
started within 48 hours of the onset of rash.
For the treatment of an initial episode of herpes, the
usual dose is 1 gm twice daily for 10 days. For the treatment of
recurrent herpes, the usual dose is 500 milligrams twice daily for 5
days. For best results, treatment should be initiated within 12 hours of
the start of symptoms.
The usual dose is 1 gram 3 times a day for 7 days.
The usual dose for the first attack is 1 gram twice a day for 10 days. For later attacks, the dose is 500 mg twice a day for 3 days. To keep the condition from returning, the dose is 1 gram once a day. If you've had less than 10 infections per year, your doctor may prescribe 500 mg once a day. The safety and effectiveness of Valtrex treatment beyond 1 year have not been studied.
Patients with kidney problems or HIV infection may need a reduced dosage.
The recommended dosage is 2 grams twice a day for 1 day, taken about 12 hours apart. Valtrex should not be taken for more than 1 day. The elderly and people with kidney problems may need a reduced dosage.
