What symptom might indicate a serious side effect of clozapine related to blood count?

The presence of sore throat and fever can indicate a serious side effect of clozapine known as agranulocytosis, a condition characterized by a dangerously low level of neutrophils, which are critical white blood cells that help the body fight off infections. If a patient develops agranulocytosis, they may experience symptoms such as sore throat, fever, and other signs of infection due to the weakened immune system. Monitoring blood counts is crucial for patients on clozapine due to this risk, as it allows healthcare providers to identify any declines in white blood cell levels early and intervene appropriately to prevent severe complications. Other options, while they may be associated with various side effects of medications, do not specifically point to this severe blood count issue associated with clozapine.
