An increasing number of patients and their families are accusing an Illinois psychiatrist of overmedicating patients with powerful antipsychotic drugs, according to the Chicago Tribune. Medicaid records show that in 2007 Dr. Michael Reinstein wrote more prescriptions for the drug clozapine than the combined number written by all doctors in Texas. Clozapine carries a so-called black box warning due to side effects including increased risk of seizure, enlargement of the heart and rapid drops in blood pressure.
