When is iontophoresis recommended for hyperhidrosis?

Iontophoresis uses a mild electrical current while the hands or feet rest in water trays. The session is designed to reduce sweat production in the treated area. It is most practical for palms and soles, and some devices or clinical protocols may address other localised areas. A clinician can help confirm that the sweating pattern fits hyperhidrosis and that the device is appropriate.

The effect needs ongoing maintenance because sweating can return when treatment is stopped. The plan may be adjusted around skin sensitivity, cracks, cuts, eczema, or discomfort. Iontophoresis is not suitable for everyone, including some people with implanted electrical devices or particular medical conditions.

Tell the clinician about pregnancy, implanted electrical devices, metal devices, heart conditions, reduced sensation, skin breaks, and medicines. Remove jewellery from the treatment area and follow the device instructions closely. Do not place hands or feet with open wounds into the trays unless a clinician has given specific advice. Report burning, persistent tingling, blistering, or worsening irritation.

Arrange a medical review if sweating starts suddenly, occurs during sleep, affects the whole body, or comes with fever, weight change, chest symptoms, faintness, or palpitations. Seek advice if the skin cracks repeatedly or becomes infected. These patterns may need evaluation for an underlying cause before treating sweat locally.

Ask which body areas can be treated, whether your medical history affects suitability, how to protect sensitive skin, and how maintenance sessions will be planned. Discuss other options if the sweating is widespread, involves the underarms, or does not improve enough.
