Generic name: NITROFURANTOIN 25mg
Dosage form: capsule, delayed release pellets
Medically reviewed on June 13, 2017.
Macrodantin should be given with food to improve drug absorption and, in some patients, tolerance.
Adults: 50-100 mg four times a day -- the lower dosage level is recommended for uncomplicated urinary tract infections.
Pediatric Patients: 5-7 mg/kg of body weight per 24 hours, given in four divided doses (contraindicated under one month of age).
Therapy should be continued for one week or for at least 3 days after sterility of the urine is obtained. Continued infection indicates the need for reevaluation.
For long-term suppressive therapy in adults, a reduction of dosage to 50-100 mg at bedtime may be adequate. For long-term suppressive therapy in pediatric patients, doses as low as 1 mg/kg per 24 hours, given in a single dose or in two divided doses, may be adequate.
