Prochlorperazine is commonly administered by which route?

• A. Intravenous
• B. Intramuscular
• C. Subcutaneous
• D. Topical

Answer: (B)

Giving prochlorperazine by intramuscular injection is most common because it provides reliable and fairly rapid absorption without requiring IV access. In many care settings, staff can administer an IM shot quickly and safely, delivering symptom relief even when a patient cannot take medications by mouth or when an IV line isn’t readily available. Oral forms can be affected by vomiting, poor intake, or slowed GI absorption, making IM administration a more predictable option for antiemetic effect. Rectal forms exist but are used less often in routine CMA practice, and topical administration isn’t appropriate for this systemic drug. If IV administration is needed, that typically occurs in hospital or acute care settings and involves more specialized nursing skills and monitoring.
