According to data released at a medical conference, patients who took Seroquel had 3.34 times more incidents of diabetes as patients on other medications such as haldoperidol.
Plaintiffs are seeking statutory, exemplary, and punitive awards as well as medical monitoring funds to pay for patients who took Seroquel to have tests for diabetes and other disorders.
In November 2006, the FDA Division of Drug Marketing, Advertising, and Communications sent a letter to AstraZeneca regarding their Seroquel sales materials. The FDA found that one of the sales aids was "false or misleading because it minimizes the risk of hyperglycemia and diabetes mellitus and fails to communicate important information regarding neuroleptic malignant syndrome, tardive dyskinesia, and the bolded cataracts precaution." The letter went on to say that the material was a cause of public health concern because it minimized the risks associated with taking Seroquel.
Furthermore, the warning letter stated that AstraZeneca's claim that the percentage of diabetes-related events is very rare (<0.01%) was misleading because adverse event reporting by patients and medical professionals is voluntary and therefore it is not feasible to get an accurate percentage of adverse diabetes-related events. The FDA also warned AstraZeneca that it omitted important information, including information that some of the adverse effects of Seroquel, such as NMS, are potentially fatal. The FDA requested that AstraZeneca respond to their warning letter by November 30, 2006, and remove all sales aids that violated FDA regulations.
Seroquel, an antipsychotic approved by the FDA in 1997, is used to control symptoms of schizophrenia including hallucinations, social withdrawal, delusions, and thought disorder. It is also used in some cases to treat the manic periods of bipolar disorder. Seroquel works by affecting neurotransmitter receptors.
