Iontophoresis uses an electrical charge to deliver medication through the skin. Known as a transdermal drug delivery system, this non-invasive method is used by physical therapists for the application of anti-inflammatory medications, usually in cases where tendons, bursa or muscles are swollen or irritated.
Iontophoresis is a good option for clients who are unable to receive injections. This pain-free methodology takes mere minutes, delivers the medication directly to the injured area and avoids the risk of injection site infection. Clients generally experience a slight tingling sensation from the low electric current that propels the medication through the skin.
