Cefalexin 500 mg is a widely prescribed antibiotic used to treat a variety of bacterial infections. It belongs to a class of medications known as cephalosporin antibiotics. Cefalexin works by stopping the growth of bacteria, effectively killing the microorganisms responsible for the infection.
 
This medication is effective against a broad spectrum of bacteria and is commonly used by healthcare providers to treat infections of the respiratory tract (like bronchitis), urinary tract (UTIs), skin and soft tissues, ear, and bones. Cefalexin is a first-generation cephalosporin valued for its reliability and effectiveness.
