How long does a session with the CEFALY® last?

A session with the Acute program lasts one hour. It should be used during the migraine attack and can be extended with an additional one-hour session if the first session did not provide sufficient relief for the migraine or if a new migraine attack occurs. A session the Prevent program lasts 20 minutes. It should be used every day, at any time of the day, although evening sessions are preferred.

Should I use CEFALY® everyday?

It is recommended to use the Cefaly daily for 20 minutes as a preventive treatment.

What if the intensity is too strong for me?

If the intensity becomes too strong for you, press the button onece to stabilize the intensity. You can also remove the device to stop the session.

Can I adjust the intensity?

Yes, by holding down the button, you can quickly increase the intensity to the desired level. You can repeat this action several times in a row until the maximum intensity level is reached.

Electrodes: How many uses?

An electrode with a magnetic connection is used with the CEFALY®. An electrode can be used between ten and twenty times. Before applying the electrode, it is very important to clean and degrease the skin on the forehead so that the electrode adheres well to the skin.
Cleaning should be done with water and soap or using a wipe provided with the device. After use, the electrode is placed back on its transparent plastic support sheet and stored in its pouch to prevent dehydration. As long as the electrode adheres well to the forehead skin, it can be used. Once your session is finished, the electrode should be reattached to its transparent plastic support sheet and stored in its pouch. Do not leave the unpackaged electrode in a dry place. It would lose its hydration and would not function properly. A few drops of tap water on the electrode gel can rehydrate it and extend its use. A fully charged battery will last approximately 2 to 3 hours of treatment, depending on the program and intensity used.

How long does it take to charge the Cefaly®?

It takes approximately 4 hours for the CEFALY® battery to fully charge. It is important that you fully charge the CEFALY before the first session.

How long will the Cefaly® hold its charge?

A fully charged battery will last approximately 2 to 3 hours of treatment, depending on the program and intensity used.

How do I know when the Cefaly® needs to be charged?

If the device emits a long sound signal when you press the button, it means the battery is down. You need to recharge it for at least 5 minutes to be able to conduct a session.

Is it painful?

The sensation produced by the CEFALY® is strange and unusual, but most people quickly get used to it after a few sessions. However, some individuals are more sensitive and may perceive the sensations produced by the CEFALY® as painful. If you find yourself in this situation, you can simply press the button during the session when the sensation becomes a bit uncomfortable to limit the intensity.

Only 1.25% of patients do not tolerate the sensation produced by the CEFALY® and therefore cannot complete the treatment.


There are no absolute contraindications. However, it is recommended to avoid using the device in the following cases:
  • You have implanted metallic or electronic devices in the head
  • You are suffering from pain of unknown origin
  • You have a cardiac pacemaker or implanted or wearable defibrillator
  • You have recent brain or facial trauma (less than 3 months)
  • Have a skin abrasion on the forehead in the area of application of the electrode
  • You have an allergy to acrylate
  • You have cutaneous hypersensitivity: +/- 5% of people present a hypersensitivity of the forehead skin and do not tolerate the sensation induced by the CEFALY Enhanced
  • You have trigemnial neralgia
  • Have ophthalmic shingles

Can pregnant women use it?

Pregnant women can safely use the Cefaly. In fact, it is recommended in such cases as it can replace medications that cannot be used.

Can children use it?
