How to read your display
When gammaCore is turned on, the display will rotate
between months or days of therapy remaining and the
number of stimulations available in a 24-hour period.
Months or Days of Therapy
gammaCore offers a set time of therapy. To
ensure uninterrupted therapy, request a refill
when your device displays 21 days remaining.
Intensity Level
Most patients use an intensity level between
15 and 25 for treatment. Your stimulation
intensity may not be the same at every use.
Stimulations remaining
Within each 24-hour period, you have access
to 30 stimulations.
Apply gel
Be sure to apply enough of the provided gel to both
stimulation surfaces. gammaCore will not work
without the gel. Use only the conductive gel provided.
Do not use other gels.
Reach the right intensity level
With the device in the treatment location, slowly
increase the intensity until you feel a downward pull
on your lip. Most people experience this at an intensity
over 15.
You should not feel pain – If you experience pain or
discomfort, decrease the intensity by pressing the lower
area of the control button.
Adjust the placement
If you don’t feel a lip pull, try making small adjustments
to the placement on your neck. Use a mirror to help
you. Apply more gel to the stimulation surfaces if it
has spread too thin while repositioning.
If the vibration spreads toward your ear, gammaCore
is placed too far back on your neck.
Treat early and as directed
For the best chance at relief, use gammaCore at the
first sign of pain and deliver additional stimulations
as needed.
Within a single treatment and as tolerated, stimulation
should be administered to the same side of the neck
where pain is usually experience.
Improvement continues over time
You may need to use gammaCore several times before
you get full benefit. It is safe to use gammaCore every day.
