Tap-water iontophoresis (TWI) using direct current (DC) is the most effective therapy in palmoplantar hyperhidrosis. Side-effects of this method are discomfort, with burning and tingling, and skin irritation, including erythema and vesicles. Incorrect use may induce iontophoretic burns at sites of minor skin injury. Elaborate safety measures are required to prevent electric shock. The aim of this study was to minimize side-effects and to increase technical and safety standards of TWI, without loss of efficacy. In a controlled blind study, treatment of palmar hyperhidrosis by alternating current (AC) or by AC with DC-offset (AC/DC) was compared with the conventional DC method. Palmar hyperhidrosis was completely controlled after an average of 11 treatments by either AC/DC iontophoresis or the conventional DC method. Virtually no effect was seen when AC without DC-offset was used for TWI. There were no signs of cutaneous irritation, or subjective sensations of discomfort when AC with or without DC-offset was employed. AC/DC iontophoresis should become the treatment of choice for palmoplantar hyperhidrosis. The mechanism of action is unknown. It is hypothesized that an interrupted stimulus-secretion-coupling leads to a functional disturbance of sweat secretion.

UI	MeSH Term	Description	Entries
D007478	Iontophoresis	Therapeutic introduction of ions of soluble salts into tissues by means of electric current. In medical literature it is commonly used to indicate the process of increasing the penetration of drugs into surface tissues by the application of electric current. It has nothing to do with ION EXCHANGE; AIR IONIZATION nor PHONOPHORESIS, none of which requires current.	Iontophoreses
D010146	Pain	An unpleasant sensation induced by noxious stimuli which are detected by NERVE ENDINGS of NOCICEPTIVE NEURONS.

D006945	Hyperhidrosis	Excessive sweating. In the localized type, the most frequent sites are the palms, soles, axillae, inguinal folds, and the perineal area. Its chief cause is thought to be emotional. Generalized hyperhidrosis may be induced by a hot, humid environment, by fever, or by vigorous exercise.	Hyperidrosis

D000328	Adult	A person having attained full growth or maturity. Adults are of 19 through 44 years of age. For a person between 19 and 24 years of age, YOUNG ADULT is available.	Adults
D012677	Sensation	The process in which specialized SENSORY RECEPTOR CELLS transduce peripheral stimuli (physical or chemical) into NERVE IMPULSES which are then transmitted to the various sensory centers in the CENTRAL NERVOUS SYSTEM.
