Iontophoresis with Dexamethasone

Iontophoresis is a physical therapy modality that combines a low-voltage electrical current with the topical application of dexamethasone medication.

Iontophoresis with dexamethasone is sometimes used for inflammatory conditions such as bursitis or tendonitis. Dexamethasone is a corticosteroid.

How Iontophoresis Works

With iontophoresis treatments, the electric current enhances the delivery of the pain-relieving medication through the barrier of the skin and the hair follicles.

In the past, experts believed that the action of iontophoresis was to push the medication through the skin. Recently, they've updated their understanding of how ionto (as it is often called for short) works. They now say it helps open up microscopic pores in the outermost layer of the skin, which allows the medication to flow freely into your tissues.

What to Expect When You Get Iontophoresis

When you have an iontophoresis, you'll lie down on a treatment table. Your physical therapist will place two electrodes, one with the pain medication applied, close to the area of inflammation. The electrodes will be connected to an iontophoresis machine. Your therapist will then work the controls on the iontophoresis machine to get enough current to overcome the barriers provided by the electrodes as well as your skin, thereby enhancing the delivery of the dexamethasone to your underlying tissue.

Because the dexamethasone is applied to your skin, iontophoresis enables a high concentration of the applied drug to reach the muscles, with few, if any, side effects.

The dexamethasone is delivered to a larger surface area, as well.

The treatment lasts between 10 and 15 minutes.
