Iontophoresis

Iontophoresis is a treatment modality used to administer an anti-inflammatory medication (dexamethasone) through a transdermal patch.  The medication is transmitted through the skin with the assistance of a small electrical current.  The dexamethasone has a negative charge so the negative electrode is attached to the treatment patch so it is driven into the skin.  A second patch is placed on the skin to carry the return current and complete the circuit.  During the treatment you may feel a slight tingling sensation.
