What kind of infections is Keflex used for?

Keflex, or cephalexin, is an antibiotic commonly used to treat a variety of bacterial infections. It is effective against skin infections, respiratory tract infections, bone infections, and urinary tract infections. Keflex works by inhibiting bacterial cell wall synthesis, making it effective against certain strains of bacteria, particularly staphylococci and streptococci. However, it is not effective against viral infections.
