This study of direct-to-consumer advertising by pharmaceutical companies reports a 330% increase in spending from 1996 to 2005. Such advertising campaigns were often initiated within 1 year after Food and Drug Administration (FDA) approval of the drug. Some experts have proposed changing regulations to prohibit such advertising during the first year after FDA approval. These data suggest that such a policy change would lead to a substantial change in the industry's advertising practices.

PUVA therapy increases the risks of both nonmelanoma skin cancer and melanoma.
