What symptom is NOT typically associated with Haldol?

Weight loss is not typically associated with Haldol (haloperidol), an antipsychotic medication. Patients taking Haldol may experience a range of side effects, but significant weight loss is not a common symptom linked to its use.

In contrast, the other symptoms mentioned are known potential adverse effects of Haldol. Neuroleptic Malignant Syndrome is a serious and potentially life-threatening reaction to antipsychotic medications, including Haldol, characterized by changes in mental status, autonomic dysregulation, and hypertonia. Severe drowsiness is also frequently encountered, as Haldol can sedate patients. Hyperpyrexia, an elevated body temperature, can occur with adverse reactions to Haldol, especially in the context of Neuroleptic Malignant Syndrome. Thus, the lack of weight loss as a common side effect makes it the correct choice for this question.
