Does iontophoresis treat hyperhidrosis?

Hyperhidrosis is sweating that is excessive for the situation and can interfere with work, study, sleep, or social contact. Iontophoresis uses shallow water trays and a mild electrical current to reduce sweat output from skin in contact with the trays. It is commonly considered for the palms and soles, while special attachments may be used for other sites.

The benefit is local and temporary. People often start with more frequent sessions and then use maintenance sessions as sweating returns. Dryness, tingling, irritation, or small skin breaks may occur. A clinician should also consider whether medicines, another illness, or widespread sweating points to a different approach.

Have the sweating pattern assessed before buying or using a device. Describe when it started, which sites are affected, whether it occurs during sleep, and how it disrupts daily tasks. Follow the device instructions closely, protect irritated skin, and discuss alternatives if the response is limited or the treatment is hard to maintain.

Arrange prompt assessment for new widespread sweating, night sweats, or sweating accompanied by fever, weakness, faintness, chest discomfort, or breathing difficulty. Stop iontophoresis and contact the treating professional if the skin becomes blistered, very painful, or persistently inflamed.

Ask whether your pattern is focal hyperhidrosis, which sites can be treated, and what maintenance schedule is realistic. Ask about precautions if you have implanted electrical equipment, metal near the treatment area, reduced sensation, or damaged skin.
