About gammaCore™

gammaCore™ sends gentle stimulation through the skin to activate the vagus nerve. The vagus nerve, which plays an important role in regulating pain, is a highway of communication between your brain and many parts of your body. This gentle stimulation provides relief from migraine and episodic cluster headache pain.

Effective and long-lasting migraine relief

  • Some adults felt relief as quickly as 30 minutes
  • Almost half of adults had little to migraine pain within 2 hours after first use
  • The majority of migraine patients who were pain-free at 2 hours remained pain-free for 48 hours

Fast, reliable relief for episodic cluster headache

  • Many patients felt significant relief as quickly as 15 minutes
  • Many patients felt relief in the majority of treated attacks
  • Many patients experience a decrease in the length and severity of their attacks
