Usual Pediatric Dose for Urinary Tract Infection

Children with chronic, recalcitrant, urea-splitting urinary infection may benefit from treatment with acetohydroxamic acid. However, detailed studies involving dosage and dose intervals in children have not been established.

Children have tolerated a dose of 10 mg/kg/day, taken in two or three divided doses, satisfactorily for periods up to one year. Therefore, an initial dose of 10 mg/kg/day orally is recommended.

Close monitoring of the patient's clinical condition and hematologic status is recommended. Titration of the dose to higher or lower levels may be required to obtain an optimum therapeutic effect and/or to reduce the risk of side effects.
