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).
250-500 mg orally every 6 hours or 1-2 g intramuscularly/intravenously every 6-12 hours for moderate to severe 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.
1-2 hours (normal renal function); prolonged to 10-30 hours in severe renal impairment (CrCl <10 mL/min)
Renal excretion as unchanged drug: 80-90% (primarily via glomerular filtration and tubular secretion); biliary/fecal: 10-20% (minor).
Primarily renal (80-90% unchanged via glomerular filtration and tubular secretion); small biliary/fecal (5-10%)
