Cephalexin 500mg is a broad-spectrum antibiotic from the cephalosporin class used to treat various bacterial infections. It works by inhibiting bacterial cell wall synthesis, causing the bacteria to weaken and eventually die. Cephalexin is particularly effective against gram-positive bacteria, including Streptococcus and Staphylococcus species, making it suitable for treating skin infections, respiratory tract infections, urinary tract infections, and bone infections.
Administered orally, cephalexin is well-absorbed, has a favorable safety profile, and is generally well-tolerated. Patients usually see symptom improvement within a few days, but completing the entire prescribed course is crucial to prevent the development of antibiotic resistance and ensure full recovery.
