Special cautions
A multiple-year study suggested this drug and other neuroleptic antipsychotic drugs commonly given to people with Alzheimers with mild behavioral problems often make their condition worse and its withdrawal was even beneficial for some cognitive and functional measures. Elderly patients with dementia-related psychosis: analysis of 17 trials showed the risk of death in this group of patients was 1.6 to 1.7 times that of placebo-treated patients. Most of the causes of death were either cardiovascular or infectious in nature. It is not clear to what extent this observation is attributed to antipsychotic drugs rather than the characteristics of the patients. The drug bears a boxed warning about this risk. Impaired liver function, as haloperidol is metabolized and eliminated mainly by the liver
In patients with hyperthyroidism, the action of haloperidol is intensified and side effects are more likely. IV injections: risk of hypotension or orthostatic collapse
Patients at special risk for the development of QT prolongation (hypokalemia, concomitant use of other drugs causing QT prolongation)
Patients with a history of leukopenia: a complete blood count should be monitored frequently during the first few months of therapy and discontinuation of the drug should be considered at the first sign of a clinically significant decline in white blood cells.
