When is iontophoresis recommended for sweaty feet?

The soles of the feet rest in shallow water trays while a device sends a mild electrical current through the water. This is designed to reduce sweat production in the treated skin. Improvement generally requires repeated sessions, and maintenance may be needed when sweating gradually returns. Moist feet can also soften skin and encourage friction, so a clinician should look for cracks, dermatitis, fungal infection, or wounds before treatment. Sudden or widespread sweating may point to a different medical issue.

Consider an assessment if wet socks, slipping, odour, blisters, or difficulty wearing shoes are affecting your routine. Mention medicines, pregnancy, implanted electronic devices, metal implants, reduced sensation, and any problem on the soles. Wash and dry the feet as advised, avoid treating open or inflamed skin, and use the recommended current setting. A record of sweating, footwear, and skin changes can show whether sessions are helping. Comfortable shoes and moisture-wicking socks may support the plan but do not replace an assessment.

Arrange prompt medical review if sweating begins suddenly, happens during sleep, involves the whole body, or comes with fever, faintness, unexplained weight change, chest symptoms, or a racing heartbeat. Seek care for spreading redness, warmth, swelling, drainage, severe pain, blisters, or numbness after treatment. A foot infection or nerve problem needs specific care.

Ask whether your foot sweating fits plantar hyperhidrosis, what skin checks are needed, how the treatment schedule is set, and which alternatives are appropriate if the soles remain irritated.
