Last year, the drug flibanserin, trade name Addyi, was approved by the US Federal Drug and Administration, the regulatory body overseeing the approval of medical drugs (among other things). The drug is intended to treat low sexual desire in females, once other concerns are ruled out (i.e., relationship problems, anxiety, etc.).
The approval was met with major criticism, as the effectiveness appeared low and the side effects can be significant. Also, many clinicians (and researchers) argue that there are more effective, non-medication ways to treat low sexual desire.
Although there isn't good data available yet, it seems like it's not been that successful - in other words, very few prescriptions have been written for the drug.
In this clip from last fall, Colbert takes a swipe at the drug, and many would likely agree.
