An Instagram post advertising a morning sickness pill has fueled a firestorm around pregnant Kim Kardashian.

Kim posted a photo of herself Monday holding the prescription drug Diclegis, a reformulated version of a pill pulled from shelves in the 1980s after widespread fears that it may have caused birth defects emerged.
