It is so sad, if this man was taking Clozapine, as has been said it causes constipation that regularly results in fatalities, but also it causes heart problems, eg, it changes the QT interval of the heart. If constipated the medicine is reabsorbs into the system and can cause overdose too. How this death was recorded as “natural” is beyond me. Clozapine last time I checked was a Hazardous Controlled Substance, with 5 black box warnings, having been removed from use due to the number of fatalities, but was reintroduced under special protocol. Disgraceful.
