US FDA releases two letters on the same day citing two different kinds of advisements for two different kinds of products, but both with a classic problem: overstatement of efficacy. And while sending multiple letters at once can be seen as bid to draw attention to its enforcement action, the move also underscores just how few letters the agency has been sending lately.

Oral contraceptive’s ad did not contain any risk information and was not submitted to US FDA beforehand, so the letter seems an easy call. But with two citations released in as many weeks, is the agency signaling an uptick in enforcement?
