The antipsychotic drug Clozaril (clozapine) caused a pair of female twins to gain over 100 pounds in 5.5 years according to a report out of Germany. Weight gain of 106 lbs and 117 lbs
One twin gained 106 pounds finally reaching a weight of 221 pounds and a body mass index (BMI) of 33.8, while the other gained 117 pounds to reach a weight of 237 pounds and a BMI of 38.1.
Schizophrenia and mild mental retardation
The female twins both had schizophrenia and mild mental retardation.
Conclusion: Genes may influence antipsychotic-induced weight gain
“Because both patients experienced considerable weight gain during treatment, our observation suggests that the antipsychotic-induced weight gain is under strong genetic control,” the authors of the paper concluded.
