Keflex Oral

Keflex® (cephalexin) is an oral medication approved for the treatment of various bacterial infections, such as skin infections, bronchitis, or urinary tract infections. It is also licensed to prevent heart valve infections (bacterial endocarditis). There are two different forms of Keflex: oral solution and capsules.
 
This antibiotic prevents bacteria from making and maintaining their cell wall. Without a cell wall, bacteria are vulnerable and ultimately die. As a result, the infection is kept from spreading within the body.
 
Both capsule and oral solution forms of Keflex are typically taken two to four times a day, depending on the particular type of infection being treated. For Keflex to work properly, you have to take it as prescribed. Make sure that you complete your entire prescription, even if you start feeling better, to ensure that the infection is completely treated.
 
In addition, never take outdated Keflex; taking any outdated medication may cause serious problems because the intended effects often change after the medicine expires.
