Which of the following is NOT a Schedule IV example?

• A. Morphine
• B. Carisoprodol
• C. Alprazolam
• D. Clonazepam

Answer: (A)

Understanding how drugs are scheduled helps explain why morphine isn’t a Schedule IV example. Morphine is a Schedule II substance, which means it has a high potential for abuse and dependence, even though it has accepted medical uses for severe pain. Schedule II drugs require strict controls—prescriptions are tightly regulated, with limited or no refills and rigorous recordkeeping.

In contrast, the other substances listed have lower potential for abuse while still having legitimate medical uses, placing them in Schedule IV. Carisoprodol is a Schedule IV muscle relaxant, and alprazolam and clonazepam are Schedule IV benzodiazepines. Their scheduling reflects a comparatively lower abuse risk and the associated prescribing flexibility. Therefore, morphine is not a Schedule IV example.
