The long term effects of prolonged use of electrical stimulation are unknown.
Stimulation should not be applied to the neck. Severe spasm of the laryngeal and pharyngeal muscles may occur and the contractions may be strong enough to close the airway or cause difficulty in breathing. Stimulation over the neck could also have adverse effects on the heart rhythm or blood flow.
