Iontophoresis is an effective, well-tolerated, and simple method for delivering medication across the skin using electricity. This is particularly beneficial when treating an isolated area rather than subjecting the whole body to the medication. A direct current is applied to an electrode containing an ionized medication (meaning that it has an electric charge to it, either positive or negative) and utilizing the principle that “like charges repel like charges”, the electric current acts as a force to “push” the medication across the skin barrier to the affected area. The medication is usually a steroid with fewer risks or side effects than a typical steroidal dose pack. This type of treatment has been used successfully to treat tennis and golfer’s elbow, jumper’s knee, achilles tendonitis, rotator cuff injuries, plantar fasciitis and other inflammatory conditions.
