Cephalexin is a powerful antibiotic belonging to the cephalosporin class, widely prescribed for treating a range of bacterial infections. It is particularly effective against gram-positive bacteria, such as Streptococcus and Staphylococcus, making it suitable for infections of the skin, respiratory tract, urinary tract, and bones. Cephalexin works by interfering with the bacteria’s cell wall synthesis, leading to cell rupture and death.
Administered orally, cephalexin is well-absorbed in the body and is known for its safety and efficacy. Patients typically experience symptom relief within a few days; however, completing the full prescribed course is essential to ensure complete eradication of the infection and prevent antibiotic resistance.
