How does Cephalexin work?

Cephalexin is a semisynthetic cephalosporin antibiotic drug that works by stopping or slowing the development of bacterial cells. It is by stopping bacteria from developing the cell wall that surrounds each cell. The cell wall defends bacteria from the exterior environment and keeps the substances of the cell together. Bacteria are not able to survive without a cell wall.

This medication should only be used to treat bacterial infections. This will not work for viral infections such as flu or the common cold. Unnecessary use or misuse of any antibiotic may lead to its decreased effectiveness.
