Alli, Xenical (orlistat) Diet Drugs Investigated for Liver Injury

After receiving 2 dozen reports of liver injury, the FDA is investigating over-the-counter Alli and its prescription counterpart Xenical. Alli is an over-the-counter weight loss aid manufactured by GlaxoSmithKline. Xenical is made by Roche.
According to the FDA news release, “Between 1999 and 2008, the FDA received 32 reports of serious liver injury in patients taking orlistat. Of those cases, 27 reported hospitalization and six resulted in liver failure. Thirty of the adverse events occurred outside the United States. The most commonly reported adverse events included yellowing of the skin or whites of the eyes (jaundice), weakness, and stomach pain.”
A few months ago, the weight loss supplement Hydroxycut, was removed from the market over similar liver concerns.
Anyone whose taken these drugs and is experiencing weakness, fever, jaundice or brownish colored urine should consult their physician immediately.
