Clinical evidence
"One of the simplest, safest, and most cost-effective treatments of hyperhidrosis. Although a number of devices are available for the administration of iontophoresis, this author prefers The Fischer."

What makes it different
Built for effectiveness, not just convenience.
Metal-free silicon-graphite electrodes
The Fischer pioneered silicon-graphite electrodes: no corrosion, no metal burns, no replacement costs, built to last the lifetime of the device and covered under warranty.
Direct and pulsed current
The only iontophoresis device that offers both direct current (most effective) and pulsed current (for sensitive patients). Competitors offer pulsed current only.
Simultaneous hand and foot treatment
Large trays let you treat both hands and both feet in the same 20-minute session, cutting treatment time in half compared to single-area devices.
Anti-shock polarity change
The Fischer's polarity change is smooth and automatic, with no shocks and no interruptions. Competitors' devices cause small electric shocks during polarity changes that cannot be disabled.
Who it treats
Hands, feet, and underarms. All three.
The Fischer is FDA-cleared for all three focal areas of hyperhidrosis. Most patients treat hands and feet simultaneously, with underarms as a separate session using the axillary attachment.
Palmar
Sweaty hands are the most common focal type. The Fischer's large trays treat both palms simultaneously in a single session.
Plantar
Sweaty feet treated at the same time as hands: both areas in one 20-minute session. No additional treatment time required.
Axillary
Underarm hyperhidrosis treated with The Fischer's dedicated underarm attachments, ergonomically designed for full coverage.
How it works
The science behind iontophoresis.
Iontophoresis uses a gentle electrical current to deliver mineral ions into the sweat pores, temporarily blocking them without drugs, without surgery, and without harming the glands.
Full treatment guide1
Fill the trays with tap water
Plain tap water is all that's needed. The minerals naturally present (calcium, magnesium, potassium) carry the electrical current into the sweat pores.
2
Place hands or feet in the trays
Both hands and both feet can be treated simultaneously. The large trays accommodate adult hands and feet comfortably without additional setup.
3
Run a 20-minute session
The device delivers a gentle, adjustable current through the water. Most patients feel a mild tingling. The Fischer automatically manages polarity changes without shocks.
4
Repeat until results are achieved, then maintain
Most patients see significant reduction in 1–2 weeks of daily treatment. Maintenance is typically 1–2 sessions per week to sustain results long-term.
Cost and coverage
How much does The Fischer cost?
Most US patients pay significantly less than the list price, often nothing at all, through insurance coverage.
With insurance
Often $0 out-of-pocket for eligible patients
Most major US insurance plans cover The Fischer as a medically necessary treatment for hyperhidrosis. RA Fischer handles prior authorization, eligibility verification, and claim submission on your behalf.

Patient stories
What patients say after treatment.
Real results from patients who tried everything before finding The Fischer.
★★★★★
I have suffered with dripping hand sweat for thirty years, tried Botox, pills, creams to no avail. This machine has reduced my sweating by 90% within 2 weeks. I am able to confidently shake hands for the first time in my life.
★★★★★
I can remember the countless pairs of shoes destroyed by my slippery feet. My RA Fischer iontophoresis machine has truly changed my life! I feel a sense of normalcy in just two weeks of treatments!
★★★★★
After trying so many different remedies for hyperhidrosis over the years, with nothing working, I was very skeptical. But this feels like a miracle machine. My palm and feet sweat have gone down 90% and my life has been forever changed.

Iontophoresis uses a gentle electrical current to drive mineral ions from tap water into the sweat pores, temporarily blocking them. The process doesn't damage the sweat glands. It simply interrupts their ability to produce sweat during and after treatment. Sessions run 20–30 minutes, and most patients see results within 1–2 weeks of daily treatment.
The Fischer offers both direct current and pulsed current; most competitors offer pulsed current only. Direct current is clinically more effective for hyperhidrosis. The Fischer also has metal-free silicon-graphite electrodes (no corrosion, no replacement cost), a smooth automatic polarity change (no shocks), and large trays that treat hands and feet simultaneously. It is also covered by most major US insurance plans, which most competitor devices are not.
Yes. Most major US insurance plans cover The Fischer as a medically necessary treatment for hyperhidrosis when prescribed by a licensed provider. Plans that commonly cover it include Tricare, Aetna, Cigna, United Healthcare, Horizon BCBS, and Select Health. RA Fischer handles prior authorization and claim submission on your behalf. Many patients pay $0 out-of-pocket.
Most patients see meaningful reduction in sweating within 1–2 weeks of daily 20–30 minute sessions. Full results develop after 2–3 weeks of consistent daily treatment. Once results are achieved, maintenance sessions (1–2 times per week) sustain them long-term. The 60-day money-back guarantee gives you plenty of time to evaluate results.
No. Most patients feel a mild tingling sensation during treatment, which is adjustable via the current intensity controls. The Fischer's gradual current ramp-up and smooth polarity changes prevent the small electric shocks reported by users of some competitor devices. Sensitive patients can start on pulsed current and transition to direct current as they build tolerance.
The Fischer is priced under $900, a one-time cost with no recurring expenses. There are no replacement electrodes, no refills, and no consumables. Compared to Botox injections ($1,000–$1,500 every 4–6 months) or miraDry ($3,000+), The Fischer is significantly more cost-effective over time. It is HSA and FSA eligible, and RA Fischer offers payment plans for patients purchasing out-of-pocket.
