This medication is a cephalosporin-type antibiotic used to treat a wide variety of bacterial infections (e.g., skin, bone and genitourinary tract infections). Cephalexin is used to treat many different types of bacterial infections such as bronchitis, tonsillitis, ear infections, skin infections, and urinary tract infections.
How Taken
Take this medication by mouth usually every 6 or 12 hours, or as directed by your doctor. You may take this medicine with food if stomach upset occurs. Antibiotics work best when the amount of medicine in your body is kept at a constant level. Therefore, take this drug at evenly spaced intervals. Continue to take this medication until the full-prescribed amount is finished even if symptoms disappear after a few days. Stopping this medication too early may allow bacteria to continue to grow, which may result in a relapse of the infection. Inform your doctor if your condition persists or worsens.
Drug Class and Mechanism
Cephalexin belongs to a class of antibiotics, called cephalosporins. They are similar to penicillin in action and side effects. They stop or slow the growth of bacterial cells by preventing bacteria from forming the cell wall that surrounds each cell. The cell wall protects bacteria from the external environment and keeps the contents of the cell together. Without a cell wall, bacteria are not able to survive. Bacteria that are susceptible to cephalexin include Staphylococcus aureus, Streptococcus pneumon
