bone marrow suppression specifically agranulocytosis is a dangerous side effect requiring frequent monitoring of WBC count

22
Q

chlorpromazine

A

typical antipsychotic

similar profile to haloperidol

23
Q

haloperidol

A

traditional antipsychotic
acts by blocking dopamine receptors and is not associated with agranulocytosis
causes extrapyramidal adverse effects

24
Q

risperidone

A

atypical antipsychotic
similar to clozapine but does not produce agranulocytosis
can cause QT interval prolongation and metabolic aberrations

marked by lifetime of voluntary social withdrawal

27
