You may feel a downward pulling on your lip- this is the most common muscle contraction seen with gammaCore use and indicates you’re in the correct treatment position. The user controls the intensity level and can increase or decrease at any time. Treatment should never be painful.

Depending on the type of headache you are treating, initial treatments can last anywhere from 4 to 6 minutes. If needed, treatments can be repeated if additional attack occurs and can be used for multiple attacks per day.
