How often must Schedule II/Controlled substances be reordered?

• A. Every 30 days
• B. Every 60 days
• C. Every 90 days
• D. Every 6 months

Answer: (A)

The main concept here is tight inventory control for high-risk medications. Schedule II controlled substances require strong safeguards and regular review, so facilities typically place orders every 30 days. Reordering on a monthly cycle helps ensure a sufficient, secure stock while keeping records accurate through monthly reconciliation and inventory counts. It also supports compliance with requirements like tracking purchases with proper documentation, since these drugs cannot be refilled and must be tightly controlled to prevent diversion. Longer gaps—60 days, 90 days, or 6 months—risk stockouts, make it harder to detect discrepancies, and increase the chance of misuse, which is why those options aren’t appropriate.
