Antibiotics Home > Cephalexin Pills

Cephalexin (Keflex®, Biocef®) is a prescription medication licensed to prevent heart valve infections and for treating various types of bacterial infections, including skin infections, respiratory tract infections, and sinus infections.
 
The pills (which actually come in capsule form) and liquid solution are typically taken two to three times a day. You can take this drug either with food or on an empty stomach; there are no dietary restrictions with this drug. Make sure that you complete your entire prescription, even if you start feeling better. This will ensure that the infection is completely treated.
 
Cephalexin is part of a class of drugs called cephalosporins. It prevents bacteria from making and maintaining their cell wall. This action eventually causes the bacteria to die and stops the spread of infection in the body (as bacteria are vulnerable and ultimately perish without a cell wall).
