Several states including Vermont are investigating claims that Eli Lilly, the manufacturer of the anti-psychotic drug, Zyprexa, marketed the drug for uses not approved by the government. Eli Lilly has settled numerous product liability lawsuits concerning Zyprexa. Zyprexa has been on the market since 1996 and the recent controversy surrounds allegations that Eli Lilly knew that a link existed between diabetes and Zyprexa and the company suppressed the information.
