In 2017, the FDA approved a hand-held device to treat cluster headaches. [34] The non-invasive device works by transmitting mild electrical stimulation to the vagus nerve through the skin on the neck. Approval was based on 2 clinical trials (ACT1 and ACT2) showing that the device was more effective than placebo in reducing cluster headache pain. [35]
