Adults: 500 mg to 1 g per 24 hours. Doses of 1.5 g to 2.0 g per 24 hours may be used for short periods in severe or extensive infections.
Children: 10 mg/kg per 24 hours.
Take with or after meals, especially fatty meals, in order to minimise possible gastrointestinal irritation and to increase absorption.
Best results are obtained when the daily dose is divided and given an 6-hour intervals. Treatment must be continued until infected tissue is replaced by normal hair, skin or nails, which requires 2-6 months for skin and hair infections, 6 to 9 months for fingernails, and at least a year for toenails.
