Delivering Treatment
7. Position the device on the side of the neck
over the treatment location. Use mild to
moderate pressure so the device makes
good contact with the skin; however, do
not apply excessive pressure to the neck.
8. Increase the stimulation intensity by repeat-
edly pressing (or holding down) the (+) button
to the maximum level you can tolerate. The
device will beep every time the control but-
ton is pushed and the display will indicate a
numerical value between 1 and 40, which
signifies the intensity of the stimulation. You
will likely feel muscle contractions at the treat-
ment location. These are normal and should
stop after the stimulation is complete. The
appropriate stimulation intensity is different for
every person.
NOTE: Neck muscle contractions during the
stimulation that are not painful are normal and
not a reason to stop the stimulation. If muscle
contractions are too strong or uncomfortable, try:
a. Removing gammaCore from the neck.
b. Lowering the stimulation intensity by press-
ing the (-) button. Be careful not to turn the
device off, unless intended (this will use up
one of the available stimulations).
c. Repositioning gammaCore on the neck over
the pulse and slowly increasing the stimula-
tion intensity again by pressing the (+) button.
If the stimulation is still intolerable, turn the
device off by pressing the (+) and (-) buttons at
the same time and discontinue the stimulation.
CAUTION: Do not turn gammaCore on again
until preparing for the next treatment. The
device counts each time the stimulation intensity
is higher than three (3) as a stimulation. The
device has a limited number of stimulations it
can deliver.
9. Delivering treatment
a. Acute treatment of episodic cluster
headache
Each self-administered treatment should
consist of three 2-minute stimulations
applied consecutively at the onset of
cluster headache pain or symptoms.
If the cluster headache attack is not aborted,
you may stimulate with an additional three
consecutive 2-minute stimulations three
minutes after the first treatment.
Treatments may be applied to either
side of the neck. You may administer gam-
maCore for up to 4 attacks (or 8 separate
treatments) per day (for a total of up to 24
stimulations per day). Please see Figure 1 at
the end of this section for an example
of the treatment for one attack.
b. Acute treatment of migraine headache
Each self-administered treatment should
consist of two 2-minute stimulations at the
onset of pain. One stimulation should be
applied to the right side of the neck and one
stimulation should be applied to the left side
of the neck.
