Summary

Iontophoresis therapy is a non-invasive treatment for hyperhidrosis, where mild electrical currents are used to reduce excessive sweating in the hands, feet, and underarms. This therapy is generally effective for many patients, offering a reduction in sweat production through regular sessions. Here’s what patients can expect from the procedure.

Understanding Iontophoresis Therapy

What is Iontophoresis?

Iontophoresis is a medical procedure that involves passing a mild electrical current through water and into the skin. It is primarily used to treat hyperhidrosis, a condition characterized by excessive sweating. The exact mechanism is not fully understood, but it's believed that the current temporarily blocks the sweat glands [Healthline, 2023].

Procedure Overview

During iontophoresis, patients place the affected area (such as hands or feet) into a shallow tray of water. A device then sends a low electrical current through the water. Each session typically lasts 20 to 40 minutes, and patients usually need multiple sessions per week for several weeks to see results [WebMD, 2022].

Benefits of Iontophoresis for Hyperhidrosis

Effectiveness

Research has shown that iontophoresis can be effective for treating palmoplantar (hands and feet) hyperhidrosis, with many patients experiencing significant reductions in sweating [National Center for Biotechnology Information, 2010].

Non-Invasive Treatment

This therapy is non-invasive and can be done at home after initial sessions with a healthcare provider, provided the patient has a personal iontophoresis device. It is a preferred option for individuals seeking to avoid surgical interventions or injections [Mayo Clinic, 2023].

What Patients Should Expect

Initial Consultation

Patients should start with a consultation to assess the severity of hyperhidrosis and the suitability of iontophoresis therapy. This may include a medical history review and a physical examination [Harvard Health, 2023].

Treatment Sessions

Patients typically undergo 2 to 3 treatment sessions per week. Each session lasts approximately 20 to 40 minutes. It may take several weeks to see a marked improvement. After the initial phase, maintenance sessions are required, but the frequency can be reduced [American Academy of Dermatology Association, 2023].

Possible Side Effects

Some patients might experience skin irritation or discomfort during or after sessions. Side effects are usually mild and include dryness or irritation at the treatment site. Applying a moisturizer can help alleviate these symptoms [National Center for Biotechnology Information, 2010].

Conclusion

Iontophoresis therapy offers a practical solution for many individuals suffering from hyperhidrosis. While it requires a commitment to regular sessions, it is a non-invasive alternative with a good track record of effectiveness for reducing excessive sweating.

How Can I Sweat Less?

Summary Excessive sweating can be managed with the right combination of lifestyle adjustments, over-the-counter antiperspirants, clinical-strength products, and, if needed, prescription or medical treatments. Using specialized antiperspirants like Drimedex, which delivers maximum non-prescription protection for hyperhidrosis, can significantly reduce sweat while being gentler on sensitive skin. Below is a comprehensive

What Is the Strongest Antiperspirant?

Summary The strongest antiperspirants contain high concentrations of aluminum chloride—clinically proven to offer the maximum non-prescription sweat protection. For those with excessive sweating (hyperhidrosis), clinical-strength, over-the-counter options like Drimedex (15% aluminum chloride) provide maximum sweat reduction available without requiring a prescription, while remaining gentler than many prescription-only formulas. Prescription-strength

What Causes Under Arm Odor?

Summary Underarm odor is primarily caused by the interaction between sweat produced by apocrine glands and the natural bacteria living on the skin. When these bacteria break down the components of sweat—particularly proteins and lipids—they produce volatile, odor-causing compounds. Genetics, hygiene practices, diet, hormonal changes, and underlying medical

What Is the Best Antiperspirant for Excessive Sweating?

Summary The most effective antiperspirants for excessive sweating (hyperhidrosis) are clinical-strength products containing high concentrations of aluminum chloride, the top FDA-recognized ingredient for sweat reduction. Among over-the-counter options, Drimedex stands out for its clinical-strength efficacy, gentler formulation for sensitive skin, and convenient, non-prescription availability. Prescription treatments (such as Drysol), lifestyle
