FDA approves the first transcutaneous electrical nerve stimulation (TENS) device, made by the Belgian firm STX-Med, for the prevention of migraine headaches.
The product, called Cefaly, is battery operated and resembles a plastic headband worn across the forehead.
Cefaly is available by prescription to patients aged 18 years and older. It should be used only once per day for no more than 20 minutes.
Other FDA-approved products, such as TEVA's (TEVA) Zecuity, treat migraine symptoms.
