FOR PROPHYLAXIS IN ADULTS AND CHILDREN:
Adults( 17 years and older):
The recommended adult dose of Flumadine is 100 mg twice a day. Study durations ranged from 11 days to 6 weeks in adult and elderly patients. In patients with severe hepatic dysfunction, severe renal impairment (CrCl 5 to 29 mL/min) or renal failure (CrCI ≤ 10 mL/min) and elderly nursing home patients, a dose reduction to 100 mg daily is recommended. Because of the potential for accumulation of rimantadine metabolites during multiple dosing, patients with hepatic or renal impairment should be monitored for adverse effects.

Children (1 year to 16 years of age):

  • Study durations ranged from 5 weeks to 6 weeks in pediatric patients.
  • In children 1 year to 9 years of age, Flumadine should be administered once a day, at a dose of 5 mg/kg but not exceeding 150 mg.
  • For children 10 to 16 years of age, use the adult dose.
