Could giving Haldol to an elderly patient with Disease cause Neuroleptic Malignant Syndrome and ultimately death?

Yes, giving Haldol (haloperidol) to an elderly patient with dementia can cause Neuroleptic Malignant Syndrome (NMS) and ultimately death. NMS is a rare but serious side effect of antipsychotic medications like Haldol. It is more likely to occur in older adults with dementia. NMS can cause a variety of symptoms, including high fever, muscle rigidity, increased heart rate, and confusion. If not treated promptly, NMS can be fatal.

For these reasons, it is important to use caution when prescribing antipsychotic medications to older adults with dementia. The lowest possible dose should be used, and the patient should be closely monitored for signs of NMS. If NMS develops, the medication should be stopped immediately and the patient should be treated with supportive care.
