What to expect from iontophoresis for sweaty palms

Each hand sits in a separate shallow tray while the device sends a low electrical current through the water. You may notice tingling, prickling, or warmth; the operator can lower the intensity if it feels uncomfortable. The initial schedule is usually more frequent, then sessions are spaced out to maintain control. Dryness, mild redness, or temporary sensitivity can occur around the palms. The response differs between people, and sweating can return when maintenance is stopped.

Attend with clean hands and remove rings, bracelets, and other metal from the treatment area. Tell the clinician about cuts, dermatitis, reduced sensation, pregnancy, a pacemaker, or other implanted electrical device. Do not treat over cracked skin unless specifically advised. Protect the palms from harsh soaps and apply a suitable moisturiser after treatment if recommended. Note changes in grip, dampness, and skin irritation between sessions; this helps determine whether the intensity or schedule needs adjustment.

Pause treatment and contact the clinic for blistering, a visible burn, persistent pain, swelling, loss of sensation, or worsening hand rash. Seek urgent care for chest pain, breathing difficulty, fainting, or sudden weakness. If sweating is new, affects the whole body, happens at night, or accompanies fever or palpitations, arrange a medical review rather than assuming it is limited to the palms.

Ask how the water level and current should feel, what to use for palm dryness, when maintenance is likely to be discussed, and whether your hand eczema or medicines alter the plan. Ask how to protect small cuts before the next session.
