Precautions
Some patients exposed chronically to antipsychotics will develop tardive dyskinesia,
Chlorpromazine should be administered cautiously to persons with cardiovascular, liver or renal disease. There is evidence that patients with a history of hepatic encephalopathy due to cirrhosis have increased sensitivity to the CNS effects of chlorpromazine (i.e., impaired cerebration and abnormal slowing of the EEG).
Because of its CNS depressant effect, chlorpromazine should be used with caution in patients with chronic respiratory disorders such as severe asthma, emphysema and acute respiratory infections, particularly in children (1 to 12 years of age).
Because chlorpromazine can suppress the cough reflex, aspiration of vomitus is possible.
Lactation: Drug enters breast milk; not recommended (American Academy of Pediatrics [AAP] states that this is "of concern")
