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.

Treat the Root Cause of Migraine Pain with CEFALY

Most migraines involve the trigeminal nerve, the largest and most complex cranial nerve. The top branch of the trigeminal nerve can be accessed through the skin on the forehead.

An External Trigeminal Nerve Stimulation device (e-TNS), CEFALY sends tiny electrical impulses through a self-adhesive electrode placed on the forehead to stimulate the trigeminal nerve, reducing the frequency and intensity of migraine attacks.

How to use your CEFALY device

1 Cleanse your skin

It's important to cleanse your skin before every CEFALY treatment session. This will help ensure the electrode attaches securely to your forehead.

  • Use soap and water to wash between and above your eyebrows. Then, dry your skin thoroughly.
  • The use of makeup-removing products is NOT recommended as a substitute for soap and water.

2 Apply the electrode

Peel the electrode from its plastic backing. Using a mirror, place the electrode so the curved area is between your eyebrows and the wings are just above your eyebrows. Firmly run your fingers over the electrode a few times until it lies flat against your skin.

  • To extend the life of the electrode, only handle it by the edges and with clean hands.

3 Connect your device

Hold your device so the magnets on the back are exposed and bring it toward your forehead until the device connects with the electrode.

4 Begin treatment

Press the button once for the 60-minute ACUTE program to relieve migraine pain. Press it twice (with a brief pause in between) for the 20-minute PREVENT program.

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.
