What Are the Alternatives to Iontophoresis?

Iontophoresis uses a mild electrical current through water or treatment pads to reduce sweating in areas such as the palms and soles. A topical antiperspirant works at the skin surface and may be easier for smaller areas. Botulinum toxin injections reduce nerve signals to sweat glands in a treated region.

Prescription tablets can affect sweating more broadly, but they may also affect other body functions and require a medical review. The right route depends on whether sweating is mainly in the hands, feet, underarms, face, or elsewhere, and whether a medicine or health condition is contributing.

Keep a short record of where sweating occurs, triggers, sleep disruption, skin irritation, and any medicines or supplements. Tell the clinician about heart, eye, urinary, or neurological conditions before discussing tablets or injections. Ask whether a topical option can be tried first and how to protect irritated skin.

For sweaty palms or feet, breathable materials, changing damp socks, and drying skin carefully can reduce friction and secondary irritation. These measures support comfort but do not treat the underlying tendency to sweat.

Seek prompt medical care when sweating starts suddenly, occurs mainly at night, is accompanied by fever, chest discomfort, fainting, breathlessness, palpitations, or unexplained weight change. Get help for dizziness, confusion, or signs of dehydration during heavy sweating.

Ask: Is this primary hyperhidrosis or a secondary cause? Which areas can the treatment cover? What side effects should I watch for? Would topical treatment or Botox for sweating suit me? How will we review the response?
