IontoDC Treatment

IontoDC is intended to use a direct current to introduce ions of soluble salts or other drugs into the body


Introducing IontoDC by Soterix Medical

IontoDC is a battery-operated medical device that uses constant weak Direct Current (upto 2.0 mA) to introduce ions of soluble salts or other drugs into the body for medical purposes.

Iontophoresis is used for hyperhidrosis treatment, delivery of local anesthetic before emergent skin puncture or dermatological procedure to reduce pain, administration of fentanyl for patient-controlled analgesia for acute pain, sweat test for the diagnosis of cystic fibrosis, etc.

IontoDC is FDA cleared for iontophoresis treatment.

What is Iontophoresis?

Iontophoresis technology is based on the principle that an electric potential will cause ions in solution to migrate according to their electrical charges. The quantity and distribution of an ion or drug delivered into and across the skin by iontophoresis is dependent on the charge and molecular weight of the ion, the strength of the electrical current applied, electrode composition, duration of current flow, and numerous other factors.

Special Features

  • Automatic Current Ramp Up/ Down
  • Current Meter
  • Reistance

Treatment Procedure

Prior to initiating treatment, prepare electrodes according to the directions for use supplied with the iontophoresis electrodes. Apply the electrodes over the treatment site and set desired current intensity (in mA) and duration (in minutes). Initiate treatment by pressing the start button. Output current will now ramp up over 30 seconds to the set current intensity. IontoDC will deliver direct current for the duration selected. The current meter will constantly display the current delivered to the patient while the resistance meter will indicate the contact quality of the set-up. Abort treatment if there is any deviation from the expected current and quality of the set-up. At the end of treatment, current will ramp down over 30 seconds.

What are the side effects?

The most common side effects are skin irritation, burning and tingling.


Aetna considers iontophoresis medically necessary for delivery of local anesthetic to reduce pain. Aetna considers iontophoresis medically necessary for hyperhidrosis if certain medications and anti-perspirants have been tried and found ineffective.

Cigna covers treatment when medically necessary for palmar, auxiliary and plantar hyperhidrosis.

Anthem considers iontophoresis medically necessary in the treatment of primary and secondary hyperhidrosis for individuals who have tried prescription strength antiperspirants without success.
