Cephalexin capsules typically start working within a few hours of the first dose, but noticeable improvement in symptoms may take 24 to 48 hours. This antibiotic is commonly prescribed for bacterial infections, such as respiratory, skin, and urinary tract infections. To ensure effectiveness, cephalexin capsules should be taken as directed by a healthcare provider, usually every 6 to 12 hours. Completing the full course is essential, even if symptoms improve early, to prevent antibiotic resistance. If no improvement is seen after a few days, consult a doctor. Always take cephalexin capsules with water and follow dosage instructions carefully.
