Read through some of the hyperhidrosis support groups online and you’ll find tons of information on ‘Doing It Yourself’ iontophoresis. These makeshift home contraptions are comprised of pie tins and car batteries.

While we certainly applaud ingenuity here at RA Fischer Co., the risks involved with DIY’ing iontophoresis simply can’t be ignored.

II. Usability

The #1 issue with DIY iontophoresis is that you have no idea how many milliamperes (mA) those batteries are putting out. Plus, as the batteries wane, you’re forced to treat yourself for longer, more frequently, because the power output isn’t the same.


Not only is DIY not FDA-Approved, but you have no idea what chemicals you could be accidentally introducing into your systems by using cheap, unregulated materials. Pie tins are usually coated in a non-stick polymer like polytetrafluoroethylene (PTFE). This is not a chemical most people would feel comfortable potentially introducing into their bodies.

III. Cost

“No amount of money ever bought a second of time.”


That’s how we feel about DIY’ing your own iontophoresis device. A homemade iontophoresis device may only cost $20 to put together, but you’re likely going to need to treat from 2-3 times as often to see the same results.


With RA Fischer Co.’s FDA-Cleared iontophoresis device The Fischer, you’ll start out at 15 – 20-minute sessions 2-3x a week. Compare that to DIY treatments, where patients admit to enduring 45 to 60-minute sessions, sometimes as often as 2 times a day.


If you could get back an extra 8 hours out of your week, what would that be worth?


Yes, The Fischer from RA Fischer Co. is able to be covered by insurance companies. We are able to work directly with many insurance carriers to get the Fischer device covered for patients. Our Treatment Specialists are able to check your insurance coverage and explain the next steps.
