Cefaly® is an FDA-approved device used as an acute treatment of migraine and to prevent migraine. This means it can be used at the beginning of or during a migraine attack. It may also be used daily to prevent migraines from happening. It is approved for people 18 and older.1
How does Cefaly work?
Cefaly is a trigeminal nerve stimulator. The trigeminal nerve runs from the eye socket up to the forehead, just under the skin. Doctors believe this nerve plays an important role in migraine pain.1
Cefaly is placed on the forehead between the eyebrows. It then sends electrical impulses to the trigeminal nerve area. Some people feel a tingling sensation during use.2
How long is it used?
For acute treatment of migraine, Cefaly is used for 60 minutes. When used as a preventive treatment, it is worn for 20 minutes a day. The intensity of the signals varies depending on whether it is used for acute or preventive treatment.2
Cefaly is reusable, rechargeable, and battery-powered.2
