What Is Cephalexin Used For and How Does It Work?

Cephalexin is a commonly prescribed antibiotic used to treat a variety of bacterial infections, including skin infections, throat infections, ear infections, and urinary tract infections. It belongs to the cephalosporin class of antibiotics and works by interfering with the formation of bacterial cell walls, ultimately killing the bacteria causing the infection. Cephalexin is not effective against viral illnesses such as colds or flu, so it should only be taken when prescribed for confirmed bacterial infections. To ensure the best results, patients must follow the prescribed dosage and complete the full course of treatment. Mild side effects like nausea or diarrhea may occur, but serious reactions are rare. Always consult your healthcare provider before use to ensure safe and effective treatment.
