A French drug maker has been found guilty of aggravated deceit and involuntary manslaughter over a weight loss pill at the centre of a major health scandal. The drug Mediator was developed for use in overweight diabetics and was on the market for 33 years. It was eventually withdrawn in 2009 over concerns it could cause serious heart problems. Hundreds of people are believed to have died as a result of the drug. Around five million people were prescribed the medicine over the course of three decades, despite various warnings over its side effects. Thousands of plaintiffs were involved in the trial, which began in 2019. Drug maker Servier had denied any knowledge of Mediator’s side effects but a court on Monday issued it with a fine of €2.7m (£2.3m, $3.2m).
