FAQs

These questions provide an initial guide for interested patients and users. However, they are no substitute for a consultation with a doctor, nor do they replace the detailed instructions in the user manuals for our devices.

Is tap water iontophoresis painful or uncomfortable because of the electric current?

This involves a low-intensity direct current, which is adjusted according to individual preference so that a typical tingling sensation can be felt. A higher current is not necessary for the treatment to be effective. Start with low current settings and increase them gradually. It is important to cover any exposed skin with cream beforehand. Otherwise, these areas of skin are significantly more sensitive to the current.

How long does it take for tap water iontophoresis to take effect?

The effects take hold at different rates for each person. If you use the device regularly, you will usually see a noticeable improvement after about a week.

To achieve quick results, it is important to set the current high enough (to feel a slight tingling sensation). Each session should last long enough (at least 15 minutes). During the first few weeks (the initial phase), you should carry out several sessions per week. It is best simply to follow the instructions in the user manual.

What contraindications should be taken into account?

Iontophoresis must not be used in the following cases:

  • Cardiac arrhythmias
  • Pacemakers
  • Implanted cardioverter-defibrillators (ICDs)
  • Pregnancy and breastfeeding
  • Intrauterine devices (IUDs) containing metal, relevant only for treatment of the feet
  • Metal implants and other conductive objects in or on the body, provided these lie in the path of the current flow between the two electrodes
  • pathological skin changes or skin defects (wounds) that cannot be covered with Vaseline
  • neurological conditions (e.g. epilepsy or impaired sensation)
  • malignant (cancerous) conditions in the treatment area
  • severe local inflammation or thrombosis (blood clot)
  • severe circulatory disorder
  • Age: hands/feet not under 6 years, armpits not under 12 years, other body parts not under 18 years

What side effects might occur?

Tap water iontophoresis is considered to have very few side effects. Follow the instructions in the user manual to avoid unnecessary side effects resulting from incorrect use. The following side effects may occur:

  • Tingling and burning during treatment due to excessive current levels or skin injuries
  • Mild but harmless electric shocks when treatment is interrupted
  • Dry skin or itching after treatment
  • Short-term skin redness after treatment, caused, for example, by increased blood circulation due to iontophoresis or by higher current densities along the water line
  • Reversible blistering
  • Electrical burns or marks caused by high localised current intensities (e.g. direct skin contact with the electrode)

Do I need special water?

No, normal tap water, which contains ions, is perfectly adequate.

Why can I change the direction of the current?

The effect of tap water iontophoresis is slightly greater on the side of the electrode where the current flows from the device into the body via the electrode. To achieve an even sweat-reducing effect on both parts of the body, the direction of the current should be changed from session to session. However, at the start of treatment, it may be advisable to maintain a consistent direction of current in order to be able to observe treatment results sooner, at least on one part of the body.

What costs does the health insurance cover?

In Germany, health insurance funds usually cover the full cost of medical aids. At most, you will be required to pay a statutory co-payment of up to 10 euros. A prescription from a doctor is generally required. Do not purchase a device yourself beforehand without consulting your health insurance fund. Otherwise, you may not be reimbursed. This is because statutory health insurance funds operate according to the so-called ‘benefit-in-kind’ principle.
