How gammaCore Works

gammaCore activates pain-relieving power through non-invasive vagus nerve stimulation

gammaCore (nVNS) activates your vagus nerve with a patented, gentle electrical stimulation, providing relief from cluster headache pain in a very different way than drugs.1

  • The vagus nerve is an important highway of communication between your brain and many parts of the body2

  • The vagus nerve plays an important role in regulating pain2

Non-invasive vagus nerve stimulation with gammaCore is believed to help block the pain signals that cause cluster attacks.2,3

  • Unlike traditional vagus nerve stimulation therapies, gammaCore stimulates the nerve non-invasively through the skin1

  • Avoids many drug-like side effects and the injecting, inhaling, or ingesting associated with medications1

  • gammaCore is FDA-cleared and has been used in Canada and Europe for several years4
