Expert advice for Cefalexin
Your doctor has prescribed Cefalexin to cure your infection and improve symptoms. Do not skip any doses and finish the full course of treatment even if you feel better. Discontinue Cefalexin and inform your doctor immediately if you get a rash, itchy skin, swelling of face and mouth, or have difficulty in breathing. Diarrhea may occur as a side effect but should stop when your course is complete. Inform your doctor if it doesn't stop or if you find blood in your stools. If you're on blood thinners, Cefalexin can interact with your medications and increase your bleeding tendencies.
