White or almost white crystalline powder
Cephalexin (cefalexin) is a cephalosporin antibiotic used to treat bacterial infections of the upper respiratory tract, the middle ear, the bones, the skin, and the reproductive and urinary systems. Cephalexin (cefalexin) works by interfering with the bacteria's cell wall formation. This weakens the cell wall, causing it to rupture, and kills the bacteria.

As cephalexin (cefalexin)is only effective against certain types of bacterial infection your doctor may perform tests to identify the organisms causing the infection before beginning treatment.

Cephalexin (cefalexin) may also be used for other purposes not listed here.
