Cefaly is a device approved by the Food and Drug Administration (FDA) for the prevention of migraine headaches. Through an adhesive electrode that is placed on the forehead, Cefaly generates precise micro-impulses to stimulate the trigeminal nerve, which is involved in most migraine headaches. Stimulation of the trigeminal nerve using Cefaly is thought to suppress activity in the fibers within that nerve that carry pain signals to the brain.
Cefaly is used to reduce migraine occurrences. It is recommended that you use Cefaly once a day for 20 minutes to prevent migraine attacks. The device allows you to increase the intensity of the impulses so that your sessions become more and more effective as you build tolerance.
Cefaly is approved for use in people 18 years and older. It is not recommended if you have a metallic or electronic device implanted in your head, if you are suffering from pain of an unknown origin, or if you have a cardiac pacemaker or an implanted or a wearable defibrillator.
For the best chance of improving your symptoms, you will need to use Cefaly for one 20-minute session every day.
Side effects from the use of Cefaly are rare. They can include intolerance of the feeling of the device on the forehead, allergic skin reaction to the electrode, fatigue during and after the session, and headache after the session.
