Cephalexin capsules are an oral antibiotic used to treat bacterial infections in the respiratory tract, urinary tract, skin, bones, and ears. Belonging to the cephalosporin class, they work by stopping the growth of bacteria. Cephalexin is commonly prescribed for mild to moderate infections and is effective against a wide range of bacteria. The capsules should be taken exactly as directed by a healthcare provider, usually with or without food, and at evenly spaced intervals. Common side effects include nausea, diarrhea, stomach upset, and dizziness. Patients allergic to penicillin or cephalosporins should use caution and inform their doctor before starting treatment.
