Cephalexin is a reliable antibiotic commonly used to treat various bacterial infections. As a first-generation cephalosporin, it targets gram-positive bacteria like Streptococcus and Staphylococcus, making it effective for skin, respiratory, urinary tract, and bone infections. Cephalexin works by disrupting bacterial cell wall synthesis, causing the bacteria to weaken and die.
Administered in oral form, cephalexin is well-absorbed and has a good safety profile with minimal side effects. It is often prescribed in doses of 250mg to 500mg, depending on the severity of the infection. Completing the full course of treatment is essential to ensure complete recovery and prevent antibiotic resistance.
