Renal Impairment

Do not use MALARONE for malaria prophylaxis in patients with severe renal impairment (creatinine clearance <30 mL/min) [see Contraindications (4.2)]. Use with caution for the treatment of malaria in patients with severe renal impairment, only if the benefits of the 3-day treatment regimen outweigh the potential risks associated with increased drug exposure. No dosage adjustments are needed in patients with mild (creatinine clearance 50 to 80 mL/min) or moderate (creatinine clearance 30 to 50 mL/min) renal impairment. [See Clinical Pharmacology (12.3).]
