Postherpetic neuralgia (PHN) is a distressing condition winch occurs after suffering from herpes zoster and it resists conventional therapies such as administration of painkiller or carbamazepine, nerve block, acupuncture and so on.
We have successfully treated a patient with PHN on the trigeminal nerve by iontophoresis, whose pain could not be alleviated by conventional therapies. Methylprednisolone and lidocaine were directly permeated into the painful skin area by iontophoresis. A significant relief of the pain was observed soon after the first application of iontophoresis and the pain disappeared after the second therapy. Moreover, there was no side effect.
We believe that iontophoresis is a valuable method for treating the pain in PHN winch showed no improvement by conventional therapies.
