I fully agree with Andrew’s comment about taking medical headlines with a healthy dose of skepticism. There is a strong pressure on the media to have eye-catching headlines, and lay scientific articles often do not fully appreciate the complexities of medical studies. That is not to say that information in the lay medical press should be ignored–far from it! It is just that they often don’t tell the full story. In this case, the side effect of Bell’s Palsey is quite significant and at a bare minimum it would attract extremely close scrutiny from the FDA and other regulatory agencies.
