Avoid weight-loss drugs
Xenical
Consumer Reports recently reviewed several thousand adverse event reports from the Food and Drug Administration that show side effects associated with the drug
Orlistat—the active ingredient in the over-the-counter (OTC) weight-loss drug
Alli and the prescription drug
Xenical.
The worrying findings have further strengthened our earlier advice: Avoid both versions of this drug.
