A patient calls the pharmacy asking if they can get an early refill on their Adderall XR (C-II) prescription because they are going on a two-week vacation. The patient states they only have a few days' supply left. According to federal law, what is the maximum number of days' supply a prescriber can provide for a Schedule II controlled substance through multiple prescriptions issued on the same day?

  1. A60 days
  2. B90 days
  3. C120 days
  4. D30 days
Show answer & explanation

Correct answer: B. 90 days

Federal law allows a prescriber to issue multiple prescriptions for a Schedule II controlled substance on the same day, provided each prescription indicates a 'do not fill before' date, and the total quantity does not exceed a 90-day supply.

Why the other options are wrong

  • A. This is not a recognized federal limit for this specific scenario.
  • C. This exceeds the federal limit for C-II prescriptions issued on the same day.
  • D. This is typically the standard maximum for a single C-II prescription without 'do not fill before' instructions.

Multiple C-II Prescriptions

Federal law allows prescribers to issue multiple prescriptions for a Schedule II controlled substance on the same day for a total extended supply.

  • Permitted for up to a 90-day total supply.
  • Each separate prescription (after the initial one) must include a 'do not fill before' date.
  • Must be for a legitimate medical purpose by a practitioner acting in the usual course of professional practice.
  • This addresses the 'no refills' rule for C-II drugs.

Memory trick: C-II: No refills, but 90-day supply is possible with staggered 'do not fill before' dates.
