How does Cephalexin work?

Cephalexin works by stopping or slowing the growth of bacterial cells. It is by preventing bacteria from forming the cell wall that surrounds each cell. The cell wall protects bacteria from the external environment and keeps the contents 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.
