How long does iontophoresis take to work for sweaty feet?

With iontophoresis, the feet sit in water trays while a mild electrical current passes through the water. Repeated sessions are used because sweating can return when treatment stops. Early improvement may show as less dampness inside socks, less slipping in footwear, or fewer interruptions to change socks. Thick soles, sensitive skin, heat, activity, and inconsistent sessions can affect the experience. A foot that remains sweaty after the first treatments does not by itself show that the method will not help.

Follow the prescribed schedule and inspect the soles and spaces between the toes before each session. Do not place feet with open cracks, active irritation, or infection into the trays without medical advice. Dry the feet carefully afterward and use only recommended moisturiser or barrier care. Note odour, damp socks, slipping, and skin comfort over time. Share this information at review so the clinician can address both sweating and any foot condition that may be maintaining irritation.

Contact the provider for blistering, increasing redness, drainage, severe burning, painful cracks, or persistent altered sensation after treatment. Arrange assessment for sudden whole-body sweating, night sweats with illness, faintness, chest symptoms, or fever. Foot odour with scaling, sores, or spreading redness may indicate a separate skin problem needing care.

When should I compare sock dampness to judge progress? What should I do if the soles crack? How often might maintenance be needed, and could my foot rash or infection affect treatment?
