Which of the following is NOT an adverse effect associated with Droperidol?

Droperidol is an antipsychotic agent that is primarily used for its antiemetic properties and as a sedative. When considering its adverse effects, hypotension, extrapyramidal reactions, and neuroleptic malignant syndrome are all known potential complications associated with the use of this medication.

Hypotension can occur as Droperidol has vasodilatory effects, which can lead to decreased blood pressure. Extrapyramidal reactions are movement disorders that include symptoms like tremors and rigidity and can occur with various antipsychotics, including Droperidol, due to its dopamine receptor antagonism. Neuroleptic malignant syndrome is a rare but serious condition often related to antipsychotic medications, characterized by high fever, muscle rigidity, and autonomic instability, making it another concern with Droperidol use.

In contrast, severe headaches are not commonly reported as an adverse effect linked to Droperidol. While headaches can result from numerous causes and medications, they are not specifically associated with Droperidol. This distinction marks severe headaches as the option that does not align with the established adverse effects of Droperidol usage. Hence, it is accurate to identify severe headaches as not being an adverse effect associated with Droperidol.
