Does iontophoresis help with excessive sweating?

During iontophoresis, the hands or feet sit in shallow trays of water while a device delivers a mild electrical current through the water. The exact mechanism is not fully clear, but the treatment temporarily reduces sweat output from the treated skin. Some devices are adapted for the underarms.

A typical plan begins with repeated sessions, then moves to maintenance when sweating starts to return. Tingling, warmth, dryness, irritation, or small cracks can occur. The treatment does not address every cause of sweating, and it will not control areas that are not placed in the device.

Discuss the pattern of sweating with a healthcare professional before starting, especially if it began suddenly or affects the whole body. Use only a device and schedule suited to you, follow its skin-contact instructions, and avoid applying treatment over broken or inflamed skin. Record which areas improve and whether dryness or irritation develops.

Seek medical advice for sudden new sweating, drenching night sweats, sweating with chest discomfort, faintness, breathing trouble, fever, or confusion. Stop treatment and contact the provider for a burn, persistent pain, marked redness, or worsening skin cracks.

Ask whether the distribution of sweating fits a condition that iontophoresis can help, which body areas can be treated, and how maintenance will be planned. Check whether implanted electrical devices, pregnancy, metal hardware, or skin disease change whether it is appropriate.
