How gammaCore Works to Stop
Your Episodic Cluster Headache Pain

A non-invasive vagus nerve stimulator
The gammaCore model shown is not currently available in the US.
What Does gammaCore Do?

gammaCore activates your vagus nerve with a safe and gentle patented electrical stimulation that travels through your skin.1,2 Once activated by gammaCore, your vagus nerve then acts to block the signals that are causing your episodic cluster headache pain.1,3 Another form of vagus nerve stimulation has been used safely for more than 20 years to treat a number of conditions.4

What Is the Vagus Nerve?

The vagus nerve—the longest nerve of the head—has been called the “great wandering protector.”5 It extends throughout much of your body and serves as a control center to regulate many body systems.5,6 The vagus nerve plays a role in regulating pain, inflammation, and mood.1,5
