Composition: Each Acyclovir STADA® 400 mg tablet contains 400 mg Acyclovir
Indications:
Treatment for herpes simplex virus infections of the skin and mucous membranes including initial and recurrent genital herpes.
Suppression of recurrent herpes simplex infections in immunocompetent patients.
Prophylaxis of herpes simplex infections in immunocompromised patients.
Treatment of varicella (chickenpox).
Herpes zoster (shingles) infections.
Dosage:
Acyclovir STADA® is orally taken.
Treatment of primary herpes simplex infections, including genital herpes: 200 mg five times daily (usually every 4 hours while awake) for 5 to 10 days.
Severely immunocompromised patients or those with impaired absorption: 400 mg five times daily for 5 days.
Suppression of recurrent herpes simplex in immunocompetent patients: 800 mg daily in two to four divided doses; dosage reduction to 400 - 600 mg daily can be tried. Higher doses of 1 gram daily have also been used. Therapy should be interrupted every 6 to 12 months for reassessment of the condition.
Prophylaxis of herpes simplex in immunocompromised patients: 200 to 400 mg four times daily.
Chronic suppressive treatment: is not suitable for mild or infrequent recurrences of herpes simplex. In such cases episodic treatment of recurrences may be more beneficial; a dose of 200 mg five times daily for 5 days has been recommended, preferably initiated during the prodromal period.
Chickenpox: 800 mg four or five times daily for 5 to 7 days.
Herpes zoster: 800 mg five times daily may be given for 7 to 10 days.
Children's doses:
Treatment of herpes simplex infections and prophylaxis of herpes simplex infections in the immunocompromised:
Children aged 2 years and over: as for adults.
Children aged under 2 years: half the adult dose.
Treatment of chickenpox:
Children over 2 years of age: 20 mg/kg, up to a maximum of 800 mg, four times daily for 5 days.
Children aged 6 years and over: 800 mg four times daily.
Children aged 2 to 5 years: 400 mg four times daily.
Children aged under 2 years: 200 mg four times daily.
Administration in renal impairment: Doses of acyclovir should be reduced in renal impairment according to creatinine clearance (CC).
CC less than 10 ml/minute:
Herpes simplex infections: 200 mg every 12 hours.
Varicella-zoster infections: 800 mg every 12 hours.
CC between 10 and 25 ml/minute:
Varicella-zoster infections: 800 mg three times daily every 8 hours.
Contraindications:
Acyclovir is contraindicated for patients who develop hypersensitivity to acyclovir or valacyclovir.
Pregnancy and Lactation:
Pregnancy:
There are no adequate and well-controlled studies in pregnant women. Acyclovir should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.
Lactation:
Acyclovir should be administered to a nursing mother with caution and only when indicated.
Adverse reactions:
Renal impairment may be associated with systemic use of acyclovir in some patients; it is usually reversible and is reported to respond to hydration and/or dosage reduction or withdrawal, but may progress to acute renal failure.
Occasional adverse effects after systemic administration include increased serum bilirubin and liver enzymes, haematological changes, skin rashes (including erythema multiforme, Stevens-Johnson syndrome and toxic epidermal necrolysis), fever, headache, dizziness and gastrointestinal effects such as nausea, vomiting and diadiarrhoea. Anaphylaxis has been reported. Hepatitis and jaundice have been reported rarely.
