Cephalexin dosage depends heavily on the specific infection being treated. Always follow your doctor’s prescription; self-treating can be dangerous. However, general guidelines exist.
Skin Infections
For skin infections like impetigo or cellulitis, adults typically receive 250-500mg every six hours. Children’s dosages are weight-based; consult your pediatrician. Treatment duration usually lasts 7-10 days. Complete the entire course, even if you feel better sooner.
Ear Infections (Otitis Media)
In children with otitis media, cephalexin dosage is determined by weight and often ranges from 25-50 mg/kg/day divided into two or three doses. Treatment typically lasts for 10 days. Always monitor for any worsening symptoms.
Respiratory Tract Infections
For respiratory infections like bronchitis or pneumonia (when appropriate), adult dosages commonly range from 250-500mg four times daily. Dosage adjustment may be needed based on severity and individual factors. A doctor will determine the appropriate duration; it is often 7-14 days.
