What is Cephalexin?

Cephalexin is a first-generation cephalosporin antibiotic that belongs to the beta-lactam antibiotic class. It functions by disrupting the synthesis of the bacterial cell wall, leading to the bacteria’s death. Cephalexin is usually prescribed in both oral and suspension forms, making it accessible for both adults and children.

Medical Uses of Cephalexin

Cephalexin is effective against a broad spectrum of bacterial infections. Its primary uses include:
