Seems these days EMT's and ER docs are challenged by the fact that there are too many new meds on the market for interaction studies to have been done and published on all the possible meds a dying patient may be taking, when the ER doc tries to save a life with an emergency med. When my Mother was getting cancer and dementia treatments along with a few other old folks meds I talked with her docs frequently. One said if we don't kill her with the treatment she might recover and live a while. Another said we don't know what to expect, but we prescribe these meds because the pharma company says they work. The psych doc even said he has seen no improvement in dementia in any patients taking dementia meds.
