Excessive sweating is a common problem and can be a source of embarrassment. Sometimes simple measures such as prescription strength antiperspirants can be helpful.
For excessive sweating of the hands and feet, iontophoresis can be helpful. This involves soaking the hands in a liquid through which a very gentle electric current is passed. During the treatment, the gentle electric current gives a very slight tingling sensation but is not uncomfortable. This can be helpful for hands and feet and can be tried in our clinic. If it proves to be helpful you can either continue to attend for treatment from our dermatologist, or you may wish to purchase your own iontophoresis machine for home use.
For persistent hyperhidrosis, dilute injections of Botox® (Botulinum toxin type A) can be very effective. The usual site of treatment is under the arms, where small evenly spaced injections are placed just under the surface of the skin. The benefit of Botox® injections on excessive sweating treatment lasts between six and nine months and can then be repeated if wished.
