Cephalexin is administered orally.
Adults: The adult dosage ranges from 1-4g daily in divided doses; most infections will respond to a dosage of 500mg every 8 hours. For skin and soft tissue infections, streptococcal pharyngitis, and mild, uncomplicated urinary tract infections, the usual dosage is 250mg every 6 hours, or 500mg every 12 hours.
For more severe infections or those caused by less susceptible organisms, larger doses may be needed. If daily doses of Cephalexin greater than 4g are required, parenteral cephalosporins, in appropriate doses, should be considered.
The elderly and patients with impaired renal function: As for adults. Reduce dosage if renal function is markedly impaired.
Children: The usual recommended daily dosage for children is 25-50mg/kg (10-20mg/lb) in divided doses. For skin and soft tissue infections, streptococcal pharyngitis, and mild, uncomplicated urinary tract infections, the total daily dose may be divided and administered every 12 hours. For most infections, the following schedule is suggested: Children 5 years and over: 250mg every 8 hour.
Granules for oral susp: Children 5 years and over: 250mg every 8 hours
In severe infections, the dosage may be doubled. In the therapy of otitis media, clinical studies have shown that a dosage of 75 to 100mg/kg/day in 4 divided doses is required.
In the treatment of beta-haemolytic streptococcal infections, a therapeutic dose should be administered for at least 10 days.
