Question 15

Clozapine requires current ANC and WBC test results prior to dispensing.

Clozapine is an atypical antipsychotic that necessitates monitoring of the absolute neutrophil count (ANC) and white blood cell (WBC) levels due to the risk of agranulocytosis, a potentially severe side effect.

A) Aripiprazole

Aripiprazole does not require routine monitoring of ANC or WBC counts. While it is an antipsychotic, it has a different safety profile compared to clozapine and does not carry the same risk of agranulocytosis.

B) Fluoxetine

Fluoxetine, a selective serotonin reuptake inhibitor (SSRI), does not necessitate ANC or WBC monitoring. Its side effects do not include significant hematological issues that would warrant such testing prior to dispensing.

C) Amitriptyline

Amitriptyline, a tricyclic antidepressant, does not require ANC or WBC level checks. Although it has various side effects, the risk of agranulocytosis is not a concern with this medication, making monitoring unnecessary.

D) Clozapine

Clozapine is the only medication among the options that mandates current ANC and WBC testing prior to dispensing due to its association with agranulocytosis. This requirement is crucial to ensure patient safety and prevent serious complications.

Conclusion

Clozapine's requirement for current ANC and WBC test results is critical due to its risk of agranulocytosis, which can lead to severe health complications. The other options do not pose this risk and therefore do not require such monitoring, making clozapine the definitive correct answer in this context.
