Uses
INDICATIONS AND USAGE Herpes Simplex Infections in Immunocompromised Patients Acyclovir Sodium Injection is indicated for the treatment of initial and recurrent mucosal and cutaneous herpes simplex (HSV-1 and HSV-2) in immunocompromised patients. Initial Episodes of Herpes Genitalis Acyclovir Sodium Injection is indicated for the treatment of severe initial clinical episodes of herpes genitalis in immuno-competent patients. Herpes Simplex Encephalitis Acyclovir Sodium Injection is indicated for the treatment of herpes simplex encephalitis. Neonatal Herpes Simplex Virus Infection Acyclovir Sodium Injection is indicated for the treatment of neonatal herpes infections.
Dosage
DOSAGE AND ADMINISTRATION CAUTION - RAPID OR BOLUS INTRAVENOUS INJECTION MUST BE AVOIDED (see WARNINGS and PRECAUTIONS ). INTRAMUSCULAR OR SUBCUTANEOUS INJECTION MUST BE AVOIDED (see WARNINGS ). Therapy should be initiated as early as possible following onset of signs and symptoms of herpes infections. A maximum dose equivalent to 20 mg/kg every 8 hours should not be exceeded for any patient. Dosage HERPES SIMPLEX INFECTIONS MUCOSAL AND CUTANEOUS HERPES SIMPLEX (HSV-1 AND HSV-2) INFECTIONS IN IMMUNOCOMPROMISED PATIENTS Adults and Adolescents (12 years of age and older) 5 mg/kg infused at a constant rate over 1 hour, every 8 hours for 7 days. Pediatrics (Under 12 years of age) 10 mg/kg infused at a constant rate over 1 hour, every 8 hours for 7 days.
Side Effects
ADVERSE REACTIONS The adverse reactions listed below have been observed in controlled and uncontrolled clinical trials in approximately 700 patients who received acyclovir at approximately 5 mg/kg (250 mg/m 2 ) 3 times daily, and approximately 300 patients who received approximately 10 mg/kg (500 mg/m 2 ) 3 times daily. The most frequent adverse reactions reported during administration of acyclovir were inflammation or phlebitis at the injection site in approximately 9% of the patients, and transient elevations of serum creatinine or BUN in 5% to 10% (the higher incidence occurred usually following rapid [less than 10 minutes] intravenous infusion).

Warnings
WARNINGS Acyclovir Sodium Injection is intended for intravenous infusion only, and should not be administered topically, intramuscularly, orally, subcutaneously, or in the eye. Intravenous infusions must be given over a period of at least 1 hour to reduce the risk of renal tubular damage (see PRECAUTIONS and DOSAGE AND ADMINISTRATION ). Renal failure, in some cases resulting in death, has been observed with acyclovir therapy (see ADVERSE REACTIONS, Observed During Clinical Practice and OVERDOSAGE ). Thrombotic thrombocytopenic purpura/hemolytic uremic syndrome (TTP/HUS), which has resulted in death, has occurred in immunocompromised patients receiving acyclovir therapy. CONTRAINDICATIONS Acyclovir Sodium Injection is contraindicated for patients who develop hypersensitivity to acyclovir or valacyclovir.
Pregnancy
Pregnancy Teratogenic Effects Acyclovir administered during organogenesis was not teratogenic in the mouse (450 mg/kg/day, PO), rabbit (50 mg/kg/day, SC and IV), or rat (50 mg/kg/day, SC). These exposures resulted in plasma levels the same as, 4 and 9, and 1 and 2 times, respectively, human levels. There are no adequate and well-controlled studies in pregnant women. A prospective epidemiologic registry of acyclovir use during pregnancy was established in 1984 and completed in April 1999.
