Aciclovir 400mg tablets are typically prescribed for herpes simplex virus (HSV) infections and chickenpox (varicella-zoster virus, VZV). Dosage varies depending on the specific condition and the patient’s health.
For adults with genital herpes, a common regimen is 400mg five times daily for 5-7 days during an outbreak. For initial episodes, treatment may extend to 10 days. Suppressive therapy to reduce outbreaks often involves 400mg twice daily.
In chickenpox, the usual adult dose is 800mg five times daily for 5-7 days. Dosage adjustments are necessary for patients with kidney problems.
Children’s dosages are significantly lower and depend on weight and age. Always follow your doctor’s instructions carefully.
