What side effect is associated with prochlorperazine (Compazine)?

• A. Hypotension and erratic muscle movements
• B. Severe agitation
• C. Dry mouth only
• D. Drowsiness without any other effects

Answer: (A)

Prochlorperazine, commonly known by its brand name Compazine, is an antipsychotic medication that can cause a range of side effects due to its action on dopamine receptors in the brain. Among these side effects, hypotension—defined as low blood pressure—and erratic muscle movements, which may manifest as tardive dyskinesia or akathisia, are particularly significant. Hypotension can occur due to the drug's effect on the central nervous system, leading to a decrease in blood pressure. Erratic muscle movements associated with prochlorperazine arise from its properties as a dopamine antagonist and can severely impact the motor functions of a patient. By contrast, the other choices do not encompass the spectrum of side effects typically linked with prochlorperazine. Severe agitation might be seen in patients experiencing either side effects of the medication or a reaction to its withdrawal, but it is not a common side effect. Dry mouth alone is a potential side effect but does not represent the broader and more severe implications associated with prochlorperazine. Drowsiness without other effects is also an incomplete picture of the medication's side effects, as prochlorperazine often leads to additional symptoms aside from just drowsiness.
