Safe and effective for migraine headache


Fast relief
Some adults felt relief as quickly as 30 minutes

Reliable relief
• Almost half of the patients had little to no migraine pain within 2 hours after first use
• gammaCore (nVNS) provided relief for more than 50% of attacks for many migraine patients

Long-lasting relief
The majority of patients who were pain-free at 2 hours remained pain-free for 48 hours

Safe and well tolerated
Patients treated with gammaCore did not experience any serious treatment-related side effects. Most side effects are mild, occur during the use of the device, and go away quickly after each treatment.
The most common side effects include discomfort and redness at the application site as well as dizziness. A tingling feeling where the device is applied is normal, but it should not cause major discomfort.
