APPENDIX G: Precautions and Warnings

Indications

Quell is intended for use as a transcutaneous 
electrical nerve stimulation device for the 
symptomatic relief and management of chronic 
intractable pain.

The device may be used during sleep. The device is 
labeled for use only with compatible NeuroMetrix 
electrodes.

Contraindications

Do not use this device if you have a cardiac 
pacemaker, implanted defibrillator, or other 
 implanted metallic or electronic device. Such 
use could cause electric shock, burns, electrical 
interference, or death.

Precautions

•  Transcutaneous electrical nerve 

stimulation is not effective for pain of 
central origin, including headache.

•  Transcutaneous electrical nerve stimulation 

is not a substitute for pain medications 
and other pain  management  therapies.

•  Transcutaneous electrical nerve stimulation 

devices have no curative value.

•  Transcutaneous electrical nerve stimulation 

is a symptomatic treatment and, as such, 
suppresses the sensation of pain that would 
otherwise serve as a protective mechanism.

•  The long-term effects of electrical 

stimulation are unknown.

•  Since the effects of stimulation of the brain 

are unknown, stimulation should not be applied 
across the head, and electrodes should not 
be placed on opposite sides of the head.

•  The safety of electrical stimulation during 

pregnancy has not been established.

•  You may experience skin irritation or 

hypersensitivity due to the electrical stimulation 
or  electrical conductive medium (gel).

•  If you have suspected or diagnosed heart 

disease, you should follow precautions 
recommended by your physician.

•  If you have suspected or diagnosed 

epilepsy, you should follow precautions 
recommended by your  physician.

•  Use caution if you have a tendency to bleed 

internally, such as following an injury or fracture.

•  Consult with your physician prior to using the 

device after a recent surgical procedure, because 
stimulation may disrupt the healing process.

•  Use caution if stimulation is applied over 

the menstruating or pregnant uterus.

•  Use caution if stimulation is applied over 

areas of skin that lack normal sensation.

•  Keep this device out of the reach of children.

•  Use this device only with electrodes and 

accessories recommended by the manufacturer.
