Adult Dosing

For most community infections, adults receive 300 mg every 12 hours or 600 mg every 24 hours for 5 to 10 days. Community-acquired pneumonia and uncomplicated skin infections commonly use the twice-daily 300 mg regimen.

Pediatric Dosing

Children are dosed by weight in mg per kg. Typical schedules are 7 mg/kg every 12 hours or 14 mg/kg once daily, with a maximum daily dose of 600 mg. Suspension strength determines the volume per dose.

$$\text{Dose (mg)} = \text{weight (kg)} \times \text{mg/kg}$$

$$\text{Volume (mL)} = \frac{\text{Dose (mg)}}{\text{concentration (mg/mL)}}$$

Renal Adjustment

Adults with creatinine clearance below 30 mL/min/1.73 m² often receive 300 mg once daily. Always verify current prescribing information and local guidelines before treating patients.
