Iontophoresis can bring temporary yet effective relief from excessive sweating of the hands and feet.


Very often, the next treatment suggested is iontophoresis. This is most effective for the hands and feet, but it is not so easy to treat the underarm area using this method.

During iontophoresis, the affected area is placed in water and a weak electric current is passed through for 20 to 30 minutes. To treat armpits, wet pads are placed in the armpit and the current is applied. There is no pain, but it may cause skin irritation and some discomfort. How it actually works to reduce sweating is not certain, but it is thought to block the sweat pores.

At first, you will need two to four sessions a week, then regular sessions at one to four week intervals. If the treatment is stopped, the sweating will return. Although treatment may initially be carried out by the NHS or a private clinic, this may be both time consuming and difficult to keep up on a regular basis so, if the treatment works for you, you may decide to buy a machine to use at home, at your own convenience.

Iontophoresis machines cost between £360 and £1,200 and there are a number of choices available to purchase in the UK.
