Iontophoresis is a universally accepted method to treat mild to severe hyperhidrosis, approved by credible organizations like FDA, international hyperhidrosis society, and American Academy of Dermatology. The mechanism of action of this technique is probably through desensitization of nerve terminals of sweat glands without physiologic damage, via passing a mild current.
In comparison with Botulinum toxin (Botox) injection or surgery, iontophoresis is the only non-invasive yet fully effective method for treating excessive sweating. Also, it is uniquely a home-use therapy enabling the patient to perform the treatments individually at home, or share a device between many users.
As a result, Iontophoresis has been announced by many specialists as the best option for treating excessive sweating.

Performing a therapy session with IontoNorm iontophoresis device

The steps of Performing iontophoresis treatment and its ease of use varies between different devices. With IontoNorm, treatment is done in 3 easy steps:
1- Setting current and time, or choosing Last Setting option (based on instructions of the user manual).
2- selecting the Start button.
3- For hands or feet, placing them in treatment trays containing tap water.
4- For underarms, covering electrodes with axillary pads, and holding each one in an underarm.
Then all you would need to do is to wait until therapy session is finished.

Time needed for completion of therapy

Treatment with iontophoresis is done in two general phases:
– Initial treatment: for someone who is just starting this treatment.
– Maintenance treatment: therapy sessions needed after completion of primary treatment.
Initial treatment is completed after 9-18 therapy sessions (based on the severity of excessive sweating) and after this phase, sweating goes back to normal.

Maintenance therapy

All methods suggested for treatment of hyperhidrosis need to be repeated. For example, local antiperspirants need to be applied continually, and Botox injections need to be repeated periodically. Iontophoresis needs to be repeated as well, and maintenance therapy should be done 1-4 sessions per month, depending of factors such as initial severity of sweating and temperature.
The difference between maintenance therapies of iontophoresis and Botox is that with iontophoresis, it is non-invasive, easy, free of adverse effects, enabling the patient to perform therapy when and where he/she wants, and being cost-free (in case of having a device) of very inexpensive (in case of performing the sessions in a clinic).

Things to do before a therapy sessions

Before starting an iontophoresis treatment session, you should:

– Remove area to be treated from extraneous material ( such as cosmetics or antiperspirants).
– Rremove metal jewelry
– Cover small cracks or minor skin damages on the areas to be treated with Vaseline or a similar product.


Like any other medical procedures, one must know about its contraindications first. If one or more of these conditions apply to you, you should not use iontophoresis:

– Pregnancy
– Breast-feeding
– Children under 5 years of age
– Heart disease
– Having a cardiac pacemaker
– Having electronic or metallic implant inside body
– Seizure or epilepsy
– Impaired sensibility in the areas to be treated
– Severe vascular disorder
– Local thrombosis in the areas to be treated
– Malignant disorders in the areas to be treated
– Large skin damages or inflammation in the areas to be treated.

Adverse effects

If a safe and medically approved device is used, iontophoresis is the only fully effective, yet free of adverse effects method for treatment of excessive sweating. Only mild and transient tingling or redness has been observed in some patients after some sessions, which quickly disappears after a session and can also be controlled with a mild anti-inflammatory product after a session.

Tolerance to treatment

Tolerance (decreased responsiveness to treatment after repeated therapies) does not
occur with iontophoresis After initial success, you can be sure continuation of therapy will be successful as well.


IontoNorm is the iontophoresis device approved by German and Swiss quality bodies.
