What is Keflex?

Keflex is a prescription medication that is used to treat bacterial infections.

Keflex works by fighting bacteria within your body.

Make sure to always read the patient information and instructions before using this medication. Always follow your doctor’s directions.

  • Keflex should only be used to treat conditions that have already been checked by your doctor.
