gammaCore Safety

Safe and well-tolerated treatment for episodic cluster headache patients

Clinical trials have demonstrated the safety of gammaCore (nVNS).1,2

  • No serious gammaCore side effects were reported in clinical trials1,2
  • Most gammaCore side effects are mild, occur during use of the device, and go away quickly after each treatment1,2

Patients may sometimes experience hoarseness, shortness of breath, or change in voice during treatment. A tingling/pricking feeling where the device is applied is normal, but it should not cause major discomfort. These effects usually stop once the treatment is completed.2

  • gammaCore has been used in Canada and Europe for several years3
  • gammaCore has been cleared by the FDA (Food and Drug Administration) for use in the United States
