In a cozy home setting, a young woman sits contentedly,she addresses her palmar (hands) hyperhidrosis using RA Fischer Co.'s original metal-free iontophoresis device, "The Fischer." Her hands are immersed in the white water bath trays, complete with blue pH-balancing foam and silicone-graphite electrodes, representing a comprehensive and effective approach to managing her condition.

The Fischer vs. DERMADRY

Dermadry is a Canadian-based discount iontophoresis company. The Fischer's modern iontophoresis treatment far surpasses theirs in terms of speed, effectiveness, and safety.

Even better: RA Fischer Co. is able to work directly with insurance companies to get the cost of the device covered for patients, whereas Dermadry is only available out-of-pocket.

RA Fischer Co. Vs. Dermadry Canada

RA Fischer Co. is the original name in iontophoresis. Since the 1950s, we have been helping countless patients finally treat their hyperhidrosis successfully.

While both The Fischer and the Dermadry are FDA-approved tap water iontophoresis devices, there are quite a few differences that make The Fischer device and RA Fischer Co. stand out.




The Dermadry is a Pulsed Current-only iontophoresis device. The Fischer features a Direct Current and Pulsed Current switch, giving patients the flexibility of both options.

Here is why that's important:
“If you go to literature and clinical studies, Direct Current is really the most effective way to treat hyperhidrosis. With Pulsed Current, the Direct Current is switched on and off in very short cycles. This results in a different awareness of the electricity, a different feeling. Literature and clinical studies tell us that the efficacy is reduced. So I recommend that if you're starting with iontophoresis, start with Direct Current. Keep it simple. This is the most effective way to see results. From my point of view, the most important thing in the beginning is to see results as soon as possible. That's why we recommend the Direct Current. For patients who may only be able to tolerate 1-3mA, if you're quite sensitive to that, the Pulsed Current might be more practical for you. But this current only works a certain portion of the time, so Pulsed Current is always less effective than Direct Current.”
– Dr. Rolf Eilers


The Fischer was the first iontophoresis device that revolutionized the way iontophoresis could treat hyperhidrosis with our silicon-graphite electrodes. Patients no longer need to worry about metal allergies or contaminant buildup on metal electrodes.


Since its introduction in 2020, The Fischer has inspired other companies to integrate similar features into their designs. The latest version of the Dermadry machine, for instance, now includes silicone electrodes.


However, the quality of these electrodes varies from the original design of The Fischer.


Unlike The Fischer’s sturdy silicon-graphite electrodes, the Dermadry machine features thin electrodes with a grid pattern. This distinction can result in reduced treatment efficiency and an increase in the chance of shock or burn.


The Fischer's waterbath trays are larger than the Dermadry's, granting palmar/plantar hyperhidrosis patients the luxury of treating both hands and both feet at the same time.

This reduces the total treatment time in half, making The Fischer 2x as fast as the Dermadry.

The Fischer iontophoresis device features a white rectangular design with a blue and grey screen, including buttons labeled "SET" and directional arrows, while the Fischer logo is discreetly located in the bottom right corner.


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. 


The Dermadry device is not covered by insurance. 


RA Fischer Co. is based in the USA to leverage its in-depth understanding of the American healthcare system and insurance landscape. This local presence allows us to effectively navigate and facilitate coverage and reimbursement processes for The Fischer iontophoresis device, ensuring seamless support for our customers in accessing their treatment for hyperhidrosis.


Our Treatment Specialists are available to assist patients at (800)525-3467 from Monday – Friday, 9:00am-4:30pm PST.

In contrast, Dermadry is a Canadian company, which may result in potential challenges when navigating the intricacies of the American health insurance system.


In the comparison of Dermadry and RA Fischer Co.’s The Fischer iontophoresis device, a key distinguishing factor is their mA settings. Dermadry offers preset mA levels, providing a standardized approach to treatment.


In contrast, The Fischer offers adjustable mA levels, allowing for a more personalized and tailored treatment experience that can cater to the specific needs of each individual user. This flexibility in mA settings with The Fischer enables users to fine-tune their treatment intensity for optimal comfort and effectiveness. This feature sets The Fischer apart in offering a more customizable approach to iontophoresis therapy.

"The Fischer Iontophoresis Device, a noninvasive treatment backed by scientific study, uses tap water to create a plug in the pores of the skin, offering hope for a sweat-free future."

Is the Fischer right for you?

Overall, the lifetime costs of ownership of The Fischer device is considerably less than older metal-based iontophoresis options.

Compared to narrow metal electrodes or compact iontophoresis options, the proportions of The Fischer’s water bath trays, pH-balancing foam inserts, and silicone-graphite electrodes conveniently accommodate simultaneous treatment of hands and feet without sacrificing effectiveness. From our experience here at RA Fischer, dual treatment is especially beneficial for pediatric hyperhidrosis patients. The shorter session duration can help them mentally embrace the treatment, which helps to ensure success. Our Fischer boasts a 98% success rate for patients!
