How does the Cefaly device work? Can you buy it in the United States?
The Cefaly device advertises itself as a CE and ISO certified migraine headache relief device. It is advertised as the first cranial analgesic etrotherapeutic device to be proven effective on migraine pain. The devices are popular in the European Union and Canada and may soon be making an appearance in the United States, though the FDA has yet to approve it for migraine pain relief. According to their website, the device stimulates endorphin producing, touch sensitive nerve fibers of the trigeminal nerve and simultaneously block the pain stimulus.
Notes and Special Information
Special note: Because the Cefaly device has not been FDA approved, it may be harder to obtain in the US, or it could be sold as a supplemental device, or even as a novelty, without health claims on the device itself. This website makes not claims as to the effectiveness of the device or any knockoff neurostimulators.
