Psychostimulants for depression in the medically ill.

Medically ill patients who show signs of depression may have problems with traditional antidepressant therapy, because of the side effect profile and the delayed onset of action of these agents. Psychostimulants such as methylphenidate and dextroamphetamine are another treatment option. The beneficial effects of these drugs are usually noted within 36 hours, and drug habituation is generally not a problem. The primary obstacle to the use of these agents for depression in medically ill patients is the hesitancy of physicians to prescribe them.
