Cephalexin 500mg is a widely used antibiotic in the cephalosporin class, known for its effectiveness in treating various bacterial infections. It works by disrupting the formation of the bacterial cell wall, which leads to cell death. Cephalexin is particularly effective against gram-positive bacteria like Streptococcus and Staphylococcus, making it a common choice for treating skin infections, respiratory tract infections, urinary tract infections, and bone infections.

This antibiotic is usually taken orally, is well-absorbed, and has a good safety profile with minimal side effects. To ensure complete recovery and prevent antibiotic resistance, patients should complete the entire prescribed course, even if symptoms improve early.
