Introduction and Objectives: Tap water iontophoresis is a promising therapy for palmoplantar hyperhidrosis. Non-affordability and nonavailability of the marketed device restrict its usage for many patients hailing from villages or small cities. Materials and Methods: In an article named "A simple user-made iontophoresis device for palmoplantar hyperhidrosis" published previously in this journal, a simple inexpensive homemade device that runs on 12 V direct current battery was described. We made a small modification by using a 220–12 V alternate current to direct current semiconductor diode–based transformer for the current supply. Results: The added innovation made the device lightweight, cheaper, and usable with domestic electric supply at home/clinic. Sustained supply of current at same voltage without dip and non-requirement to change/replace battery are added advantages. Cost of the whole assembly is ₹310. Working and clinical efficacy of our device were comparable to the commercially available apparatus as reported by 13 patients who received thrice a week of 15min sessions with our device. Mild electric pricking sensation was felt by all patients. Four of thirteen reported that pricking sensation was a bit more with our device as compared to the marketed device. No calibration for intensity is available in our device. Conclusion: This simple to assemble and inexpensive device makes iontophoresis applicable in many needy patients with similar efficacy and few limitations compared to expensive marketed devices.
