In the News Charles Bishop, age 15, killed himself in January 2002 by crashing a small plane into a Tampa high rise office building. His mother believes his suicide was caused by the prescription drug, Accutane, manufactured by Hoffman-LaRoche (HLR). The charge is that HLR has been aware of the medication causing depression, psychosis, and suicidal tendencies. HLR claims that 13 million people have safely used Accutane since 1982. The company has investigated “minor and rare” reports of adverse psychological effects but found “no scientific basis to link to either depression or suicide.” Intro to Epidemiology – Investigation 3-1: In the News
In the News The Accutane packaging warns against possible psychological effects. Toxicologists found no traces of Accutane in the boy’s system. The suicide note stated that he was acting alone but supported efforts of Al Qaeda. Suicide is one of the leading causes of death in teenagers and young adults. Since 1992, more than 500 adverse reactions to Accutane have been recorded by national and international agencies. Intro to Epidemiology – Investigation 3-1: In the News
