The Diet Drug Orlistat (XENICAL) and Gallstones
[hide all summaries]
Yet another problem has been detected with this diet drug whose approval we opposed and that we have been attempting to get banned. The FDA found 37 cases of gall stones in patients using orlistat. This, in addition to inhibiting the absorption of important vitamins such as A, D, E and K as well as evidence that the drug can cause pre-cancerous abnormalities in the colon of animals, further emphasizes why this barely effective drug should not be used, either in the prescription version called Xenical or the about-to-appear over-the-counter version, Alli.
