When working with Cephalexin, an oral antibiotic that fights a range of bacterial infections. Also known as Keflex, it belongs to the penicillin class and is frequently prescribed for skin, bone, and urinary tract infections. In simple terms, Cephalexin treats bacterial infections, it belongs to the penicillin family, and proper dosage reduces the risk of resistance. Antibiotic stewardship requires awareness of side effects, and Cephalexin’s safety profile makes it a go‑to option for many primary‑care doctors.
Understanding how Cephalexin works helps you follow the right dosing schedule. The usual adult dose ranges from 250 mg to 1 g every 6–12 hours, depending on infection severity. Children receive weight‑based dosing, typically 25–50 mg per kilogram daily. Taking the medicine with food can lessen stomach upset, while missing doses may give bacteria a chance to become resistant. Common side effects include mild diarrhea, nausea, and rash; serious reactions such as allergic shock are rare but need immediate medical attention. Drug interactions are limited, but you should inform your doctor about any blood thinners or oral contraceptives you’re using, as Cephalexin can occasionally affect hormone levels. For patients with penicillin allergy, alternatives like macrolides or doxycycline are considered, highlighting the importance of personalized antibiotic choice.
