How CEFALY Works
CEFALY works by targeting the primary pathway for migraine pain: the trigeminal nerve. It uses external trigeminal nerve stimulation (eTNS) — a precise electrical impulse — to stimulate and desensitize the trigeminal nerve over time.
People with migraine have hypersensitive nervous systems that over-react to stimuli, causing pain and neurological dysfunction. The trigeminal nerve — a multi-branched nerve in the head and face — is the major conductor of migraine pain.
How to treat migraine with CEFALY
CEFALY relieves migraine pain and reduces migraine frequency.
CEFALY transmits a mild electric current to the trigeminal nerve through an adhesive electrode worn on the forehead.

ACUTE treatment
Use the ACUTE program at the first sign of a migraine attack to relieve pain.
If you're new to using CEFALY, stabilize the intensity at a level that is comfortable for you. Try increasing the intensity over times as you get used to the device.

PREVENT treatment
Use the PREVENT program every day to prevent future migraine attacks.
Occassional or brief use of the PREVENT mode will not be effective. Just like you need a regular workout routine to build muscles, you need a daily PREVENT routine to desensitize the trigeminal nerve.
How to use your CEFALY device
How to get the best results with CEFALY
You’re in control. Briefly press the device button anytime during the first 14 minutes of a session to stabilize the intensity when you feel a strong vibration or stimulation sensation that is not painful.
Find your sweet spot: a stimulation level that’s comfortable for you and effective for migraine. You don’t need to reach full intensity to benefit from treatment with CEFALY.
Because CEFALY is a therapeutic device, you should pause your usual activities during treatments. We recommend using CEFALY while sitting or reclining, with the head tilted back.
Just as it takes more than two or three workouts to build muscles, it takes more than just a few sessions with CEFALY to change the behavior of the trigeminal nerve. Consistent, daily use is required.
If you’re not satisfied, you can return the device for a refund within 90 days.
Your CEFALY works with gel electrodes that can be reused several times. When the electrodes dry out or become dirty, they must be replaced.
Use the free CeCe Migraine Management app to record your CEFALY sessions, set treatment reminders and log migraine attacks. CeCe syncs with the CEFALY Connected to show you session intensity and time remaining.
