DOSAGE AND ADMINISTRATION Acute Treatment of Herpes Zoster 800 mg every 4 hours orally, 5 times daily for 7 to 10 days. Genital Herpes Treatment of Initial Genital Herpes 200 mg every 4 hours, 5 times daily for 10 days.

Alternative regimens have included doses ranging from 200 mg 3 times daily to 200 mg 5 times daily. The frequency and severity of episodes of untreated genital herpes may change over time. After 1 year of therapy, the frequency and severity of the patient’s genital herpes infection should be re-evaluated to assess the need for continuation of therapy with acyclovir. Intermittent Therapy 200 mg every 4 hours, 5 times daily for 5 days. Therapy should be initiated at the earliest sign or symptom (prodrome) of recurrence. Treatment of Chickenpox Children (2 years of age and older) 20 mg/kg per dose orally 4 times daily (80 mg/kg/day) for 5 days. Children over 40 kg should receive the adult dose for chickenpox. Adults and Children over 40 kg 800 mg 4 times daily for 5 days. Intravenous acyclovir is indicated for the treatment of varicella-zoster infections in immunocompromised patients. When therapy is indicated, it should be initiated at the earliest sign or symptom of chickenpox. There is no information about the efficacy of therapy initiated more than 24 hours after onset of signs and symptoms. Patients With Acute or Chronic Renal Impairment In patients with renal impairment, the dose of acyclovir should be modified as shown in Table 3: Table 3. Dosage Modification for Renal Impairment Creatinine Adjusted Dosage Regimen Normal Dosage Regimen Clearance (mL/min/1.73 m 2 ) Dose (mg) Dosing Interval 200 mg every 4 hours >10 200 every 4 hours, 5x daily 0-10 200 every 12 hours 400 mg every 12 hours >10 0-10 400 200 every 12 hours every 12 hours 800 mg every 4 hours >25 800 every 4 hours, 5x daily 10-25 800 every 8 hours 0-10 800 every 12 hours Hemodialysis For patients who require hemodialysis, the mean plasma half-life of acyclovir during hemodialysis is approximately 5 hours. This results in a 60% decrease in plasma concentrations following a 6-hour dialysis period. Therefore, the patient’s dosing schedule should be adjusted so that an additional dose is administered after each dialysis. Peritoneal Dialysis No supplemental dose appears to be necessary after adjustment of the dosing interval.
