About gammaCore

The gammaCore therapy is the first of its kind: a non-invasive vagus nerve stimulator (nVNS) that produces a mild electrical signal to treat migraine and cluster headaches.

  • Non-drug therapy. No injecting, inhaling or ingesting.
  • Flexible treatment option that can be used alone or with your existing treatments.
  • No surgery. No invasive procedure.
  • Minimal side effects.
  • Portable.

gammaCore is a hand-held, portable device, about the size of a mobile phone that generates a unique electrical signal. A conductive gel is applied on the stimulation surfaces of the device and it is placed on the neck. Each dose takes approximately 2 minutes to administer (you may require more than one dose per treatment).

How does gammaCore work in Migraine & Cluster Headaches?

It is not certain how vagus nerve stimulation treats and prevents migraines and cluster headaches, but data suggest that it may work by sending signals into the brain that reduce the amount of a chemical called glutamate, that has been associated with headache symptoms.*

Why Use gammaCore?

The gammaCore therapy provides a safe and effective non-invasive treatment for migraines, cluster, and some other headaches, without the side effects associated with drugs. The device is portable and easy to use. It can easily be incorporated into your daily routine.
