In January 2018, the FDA approved a vagus nerve stimulator (nVS) for the treatment of migraine pain in adults. The hand-held, noninvasive device was previously approved for treating episodic cluster headache pain. The prescription-only device is placed over the vagus nerve in the neck and releases a mild electrical stimulation to the nerve's afferent fibers. Approval was based on the Prospective Study of vNS for the Acute Treatment of Migraine (PRESTO) of 243 patients with episodic migraine. Significantly more patients in the nVNS group were pain free at 30 minutes (12.7%) compared to those who received sham treatment (4.2%). [89]
