Cefalexin is used to treat the following infections caused by bacteria that can be killed by cefalexin:

If you develop a serious rash or another of these skin symptoms, stop taking cefalexin and contact your doctor or seek medical attention immediately.
Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines, including medicines obtained without a prescription. This is especially important of the following, as they may interact with your Cefalexin:
