The IontoPatch 80 allows patients to take pain relief iontophoresis on-the-go with no wires and no batteries. The self-contained wireless technology allows for a dosage of up to 80 mA-min to be delivered over a 14-hour period. This patch features a lower current, so it's ideal for those with sensitive skin as the longer wear time minimizes the risk of skin irritation. As convenient as can be once the technician applies the medication to the IontoPatch and the patch is placed on the patient. Because of no wires, the patient is free to go back to their lifestyle, which means less time waiting in a clinic. Once the prescribed dose has been delivered, the patch shuts off automatically. 6 complete treatment kits come in each box.
