Home-Made Iontophoresis Machine: What to Know

Iontophoresis passes a mild electrical current through water to affect sweating in treated areas, commonly the hands or feet. A homemade setup may have no reliable current limit, insulation, polarity control, timer, or protection against damaged wires. Water, metal, and electricity also create a shock and burn hazard.

Excessive Sweating](/symptoms/excessive-sweating/) can have different causes. A clinician can check the pattern, medicines, skin condition, and symptoms affecting the whole body before treatment.

Do not connect household batteries, chargers, exposed wires, or modified appliances to water. Use a purpose-built [Iontophoresis Device](/technology/iontophoresis-device/) only as its manual describes. Avoid treatment over broken or infected skin, metal implants in the current path, or areas with reduced sensation unless a clinician has advised you.

A regulated treatment may be called [Iontophoresis](/treatments/laser-and-energy/iontophoresis/). If it is unsuitable or insufficient, a clinician may discuss [Botox For Sweating](/treatments/injectables/botulinum-toxin-for-hyperhidrosis/).

After an electrical incident, switch off the power without touching an unsafe source, move away, and seek urgent medical help for chest pain, fainting, breathing difficulty, confusion, burns, or persistent tingling. Arrange routine care for new widespread sweating, night sweats, fever, or unexplained weight change.

Ask whether your sweating pattern fits iontophoresis, which body areas can be treated, how to protect your skin, what conditions or devices make it unsuitable, and when another treatment should be considered.
