Iontophoresis
Iontophoresis uses a simple device to treat
excessive sweating of the hands (palmar hyperhidrosis) and feet (plantar hyperhidrosis).
It is particularly useful for people who’ve tried prescription strength antiperspirants
but find that they need a stronger treatment. Used correctly and adjusted
to individual situations, iontophoresis has proven to have a very high success rate (83% according to the American
Academy of Dermatology) for people with sweaty palms and sweaty feet.
Iontophoresis uses water to conduct a mild electrical current through the skin’s surface.
It’s not entirely understood how or why iontophoresis works, but it’s believed that the
electric current and mineral particles in the water work together to microscopically
thicken the outer layer of the skin, which blocks the flow of sweat to the skin’s surface.
Once this sweat output is blocked or interrupted, sweat production on the palms and soles is,
often suddenly and dramatically, "turned off".
How to Use Iontophoresis Effectively
During iontophoresis, patients sit with hands or feet, or both, immersed in shallow
trays filled with water for a short period of time (20 to 40 minutes) while the device
sends a mild electrical current through the water. The process is repeated every other
day for five to ten days or until sweating is reduced to a comfortable level. Once the desired dryness has been
achieved, patients are switched to a maintenance schedule, ranging from once per
week to once every four weeks, depending on the individual. To maintain dryness,
iontophoresis must be repeated as soon as sweating begins to return.
Sometimes, tap water in certain geographic locations may be too soft for
iontophoresis to work. That is, it doesn’t contain many minerals
or electrolytes (tiny particles that help the electric current travel through
the water and into the skin). Adding about a
teaspoon of baking soda to the trays of water will take care of this.
If iontophoresis with plain tap water or tap water
with baking soda doesn't produce the desired dryness,
a prescription medicine called an anticholinergic may be added to the water.
In the majority of cases this works and causes the palms and soles of the
feet to stop sweating.
Women who are pregnant, people with pacemakers, or substantial metal implants
(such as joint replacements), cardiac conditions, or epilepsy should not use
iontophoresis. All jewelry should be removed before iontophoresis.
If excessive dryness of the skin occurs, moisturizers are recommended.
Skin abrasions, cuts, and hang nails should be covered with Vaseline or a similar
barrier before iontophoresis to prevent skin irritation. If the skin along the
"water line" becomes irritated due to iontophoresis, Vaseline should be applied to
that area before each treatment. To relieve skin irritation that has already occurred,
a simple 1% hydrocortisone cream is recommended. Patients are often concerned about
getting an electric shock during iontophoresis but the current used is not strong enough
to cause harm. It can startle you, however, so your doctor will teach you how to
avoid such shocks. Iontophoresis is not usually recommended for excessive
underarm sweating (axillary hyperhidrosis) because the
skin in the armpits is likely to be irritated by the
process and because it is prohibitively difficult to
perform iontophoresis on the underarms.
Successful iontophoresis requires a learned technique so it’s very important that
you find a healthcare professional who can coach you through the correct usage of iontophoresis
in his or her office. If you and your doctor decide that iontophoresis is a
good treatment choice for your situation, your doctor
can write you a prescription for a home-use
iontophoresis machine. In the United States, experts recommend the iontophoresis machine available through
R.A. Fischer Company. This machine costs about $675.00
(Other, less expensive, over-the-counter devices have been found to yield
unsatisfactory results.) Patients in the U.K. are advised to look into machines made by
STD Pharmaceutical.
To help with the process of obtaining reimbursement from a U.S. health insurance organization
for the purchase of a home-use iontophoresis machine from the R.A. Fischer Company, ask your doctor
to complete this Medical Insurance Claim Statement Form and to submit
it for you.
