French Drug Watchdog Warns Against Two Diet Pills, Echos Report

France’s drug regulator warned against potential side effects of diet pills sold by GlaxoSmithKline Plc (GSK) and Roche Holding AG (ROG),Les Echos reported.

Roche’s Xenical and Glaxo’s Alli both contain an active ingredient called orlistat which might cause rare types of hepatitis, the newspaper said. The European Medicines Agency, Europe’s drug regulator, decided to study the matter last week, according to Les Echos.
