Which of the following is a common side effect of antipsychotic medication?

Antipsychotic medications are known to cause a variety of side effects, and among those, dry mouth is particularly common. It occurs due to the anticholinergic effects of many antipsychotic drugs, which can inhibit saliva production. Fatigue can also be a side effect, as these medications can cause sedation and lethargy in some patients, affecting their energy levels and overall alertness. While hyperactivity is less commonly associated with antipsychotics—since these medications are primarily used to reduce agitation and psychotic symptoms—it can occur in some individuals as a paradoxical reaction. Thus, recognizing that antipsychotics have a broad range of side effects, including dry mouth, fatigue, and in certain contexts, hyperactivity, illustrates why the response that includes all these options is accurate.
