Frequently Asked Questions

General questions 
All of the I2m machines work in the same way and the results will be the same. With the Idrostar Pro Pulse and Idrostar+ you have the additional option of a pulsed current which is most suitable for treating the axillae and sensitive skin.
A DC current is a continuous current whereas a pulsed current is the same current but pulsed at a high frequency to reduce the intensity.
All machines are suitable for home, hospital or clinic use. Idrostar - The Idrostar is compact, portable and powered using four AA batteries. Rechargeable batteries are compatible with this unit. The idrostar has one generator and comes with two water trays which can treat two extremeties at once. For example both hands or both feet or one hand and one foot or the axillae. When treating both hands you will need assistance to control the dial for the current. Idrostar+ - The Idrostar+ is compact, portable and powered using four AA batteries. Rechargeable batteries are compatible with this unit. The idrostar has one generator and comes with two water trays which can treat two extremeties at once. For example both hands or both feet or one hand and one foot or the axillae. There is an option of buying a remote control for the idrostar+ which means no other person needs to be present when treating the hands. This machine also has a pulsed current which is most suitable for treating the axillae and sensitive skin. i2ma - The i2ma is powered by an inbuilt rechargeable battery. For safety reasons the machine works independently of the mains. The battery will need charging prior to treatment, please see the instruction manual for further information. The i2ma has one generator and comes with four water trays but can only treat two extremeties at once. For example both hands, both feet, one hand and one foot or the axillae. When treating both hands you will need assistance to control the dial for the current. Iomax 4 - This machine is no longer available. It has been superseded by the Idrostar Pro Pulse. Idrostar Pro - This machine is no longer available. It has been superseded by the Idrostar Pro Pulse. Idrostar Pro Pulse - The Idrostar Pro Pulse has two generators and comes with four water trays and can treat both hands and feet simultaneously. It is also possible to treat just two extremities by using just one of the generators. A remote power control system allows the patient to control the intensity of the current without assistance.
A circuit is a continuous loop through which the current can travel. A circuit is created when your hands and/or feet are placed in the water in the baths or/when the wet axillae pads are in place and all the necessary leads are connected (please see the wiring diagrams on the 'Instructions for use' page). A circuit will need to be completed before the current can flow.
The current will not increase on the display if the electrical circuit is not complete. Check that all leads are properly connected and that you are in the correct treatment position. There must be a full circuit with your hands and/or feet in the water in the baths or the wet axillae pads in place and all of the necessary leads are connected before the current will increase.
For the treatment of hands and feet - You should feel a 'pins and needles' type sensation, but this should not be uncomfortable. You should increase the current slowly to a tolerable level but this must not exceed 20mA. For the treatment of the axillae - Some people report no feeling at all but this does not mean you should increase the current to more than the recommended level. The sponge pockets should be kept as wet as possible for the treatment. We recommend no more than 5mA initially and never exceed 10mA when treating the axillae because the skin is more sensitive. Mild skin redness has been reported. This treatment is not recommended in patients under the age of sixteen, without prior medical consultation.
The sensation of the passage of current varies greatly from one person to another. Some people feel strong, even unpleasant, sensations at low levels of current while others feel practically nothing. The level of the current will differ from person to person.
This redness is due to the vasodilation of the skin blood vessels and is quite common. If it becomes troublesome we recommend putting a thin layer of petroleum jelly, such as Vaseline, on the wrist line or just on/above the water level on the feet. If during treatment you feel a sharp occasional pain at a precise point on the palm of your hand or the sole of your foot you may have a small cut in the skin. Stop the treatment by bringing the current gently back to zero and check to see whether you have any cuts in the skin which is immersed in the water, as this may cause a mild electrical burn. If you find a cut, dry the area thoroughly and apply a small amount of Vaseline over the cut to protect it from the current. If the red patches are sore or inflamed after treatment we recommend you apply a suitable emollient cream or seek advice from your pharmacist or GP for an appropriate product.
It is not a problem if you only miss one treatment, just continue following the protocol the next day. If you miss several sessions then we recommend you start the treatment protocol again from the beginning.
The mineral content of your tap water may affect the success rate of the treatment. The mineral content of the water is important for the treatment to work, we have seen that by increasing the mineral content in areas of very soft water users get better results. Please contact our customer services department for alternatives to tap water.
If the metal implant is not in the path of the current or in the immediate treatment area then there is no problem having iontophoresis treatment. For example, if the implant was in your leg and you were treating your hands, the current is not going to pass through your legs, so there is no problem. You would not however be able to treat your feet, as this would be a contra-indication. We do advise removing all jewellery around the areas of treatment. If in any doubt then contact our customer services and we can seek advice from the manufacturer.
Please refer to your instruction manual for the water volume for your machine. The water conducts the current, putting in too much water can be counter-productive. Put in just enough water to cover the skin on the palms of your hands and the soles of your feet. If using the axillae pads, the wetter these are the better.
Usually if you treat the palms of your hands or soles of your feet this will resolve the hyperhidrosis.
The sponge pocket needs to have a good contact with the skin surface, if you feel that there is a need for hair removal to achieve this then we recommend shaving or trimming at least 3-4 days prior to treatment.
The recommendation is to leave treatment for 3-4 days after shaving or waxing.
Please seek medical advice before commencing treatment on children. The basic treatment is the same as for adults, but because the skin is thinner we suggest starting with pulsed current. If the child is able to tolerate a higher level of pulsed current we suggest that he/she uses direct current for the hands and feet, as the treatment may be more successful. Children should not go above 15mA with direct current.

  Machine Specific Questions
To avoid corrosion. Corrosion is not covered by the manufacturer's warranty.
The machines are supplied with four Duracell AA batteries. In our experience the higher quality, long life batteries e.g. Duracell and Eveready perform consistently and cause less problems. Lower quality batteries vary in size and quality quite considerably and are more prone to leakage which will cause corrosion.
Please see your instruction manual provided with your unit.
