Seroquel, manufactured by AstraZeneca, is an atypical antipsychotic used for the treatment of schizophrenia and bipolar disorder as well as anxiety disorder, post-traumatic stress syndrome, obsessive-compulsive disorder, and sleep disorders. Seroquel has been linked to hyperglycemia, diabetes, and pancreatitis. Patients taking Seroquel should be monitored closely for signs that they are developing diabetes. Additionally, doctors should carefully screen patients before prescribing Seroquel, looking at family history for obesity and diabetes as well as the patient's weight, blood pressure, and cholesterol levels.
