Miscellaneous Systemic Drugs

The drugs discussed in this chapter have disparate structures and mechanisms of action and are used in relatively unique circumstances in dermatologic care, often after more familiar remedies fail. Some of these medications can be found over-the-counter at the corner grocery store. Others carry such significant risks that they are available only in strictly controlled circumstances. Some cost very little, whereas for others, cost may prove prohibitive. Although many of these drugs have limited US Food and Drug Administration (FDA) indications for dermatologic use, they are increasingly being used as data to support their efficacy accumulate.
