300 mg orally twice daily for 10 days; or 600 mg orally once daily for 10 days (for community-acquired pneumonia, acute exacerbations of chronic bronchitis, sinusitis, pharyngitis/tonsillitis, uncomplicated skin infections).

1.7 hours (range 1.2–2.3 h) in healthy adults; prolonged to 3.2–6.6 h in renal impairment (CrCl <30 mL/min); no significant change in hepatic impairment.
Terminal elimination half-life is 1.5-2 hours; prolonged to 3-5 hours in moderate renal impairment (CrCl 30-50 mL/min) and up to 10-20 hours in severe impairment (CrCl <10 mL/min); dosing adjustment required for CrCl <50 mL/min.
Renal excretion as unchanged drug: 80-90% (primarily via glomerular filtration and tubular secretion); biliary/fecal: 10-20% (minor).
