Cephalexin, commonly known by its brand name Keflex, is a type of antibiotic that belongs to the cephalosporin class. It is widely used to treat various bacterial infections, and its effectiveness has made it a popular choice among healthcare professionals. In this article, we will explore the medical uses and benefits of cephalexin, as well as its potential side effects and considerations.
Cephalexin works by interfering with the synthesis of the bacterial cell wall, ultimately leading to the death of the bacteria. Its broad-spectrum activity makes it effective against a range of Gram-positive and Gram-negative bacteria, including Staphylococcus aureus, Streptococcus pneumoniae, and Escherichia coli. This versatility has contributed to its widespread use in treating various infections, from skin and soft tissue infections to respiratory tract infections.
