Paxil's manufacturer, GlaxoSmithKline, has recently lost a number of lawsuits because it knowingly concealed many years of negative study data about the unsafe adverse reactions to Paxil. Glaxo's hidden study data existed before many of the drugs were FDA approved. This reveals that pharmaceutical companies knew about all the problems and only allowed findings from positive clinical trials to become public. Yet a pamphlet, “Is Paxil addictive?” geared for doctors and patients reads, “Paxil has been studied both long and short term use and is not associated with dependence or addiction.”
