Cephalexin dosage for children depends heavily on weight and the specific infection being treated. Always follow your doctor’s prescription.
Generally, the recommended dosage is 25-50 mg per kilogram of body weight per day, divided into two or four doses. For example, a 20 kg child might receive 500 mg daily, split into two 250 mg doses.
However, this is just a guideline. Infants and children with kidney problems may require lower doses. Premature infants and newborns need particularly careful dosing adjustments. Your pediatrician will determine the appropriate dose based on your child’s individual needs and health status.
| Infants (under 3 months) | 25-50 | Every 12 hours |
| Children (3 months – 12 years) | 25-50 | Every 6-8 hours |
| Adolescents (12 years and older) | Refer to adult dosing guidelines | – |
