A pharmacy receives a prescription for Adderall XR (amphetamine/dextroamphetamine) for a 12-year-old patient. The prescription is for a 90-day supply and indicates 'do not fill until' specific future dates for each 30-day increment. What is the maximum total day supply of Adderall XR that a prescriber can issue using multiple prescriptions for this Schedule II medication?

  1. A90-day supply
  2. B60-day supply
  3. C120-day supply
  4. D30-day supply
Show answer & explanation

Correct answer: A. 90-day supply

Federal law allows prescribers to issue multiple prescriptions for a Schedule II controlled substance, written on the same day, for a total of up to a 90-day supply. Each prescription must indicate 'do not fill until' a specific date.

Why the other options are wrong

  • B. While possible, it's not the maximum allowed by federal law for multiple prescriptions.
  • C. 120-day supply exceeds the federal maximum for multiple C-II prescriptions.
  • D. A single C-II prescription is typically for a 30-day supply, but multiple prescriptions can extend this.

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 supply of up to 90 days, provided each subsequent prescription has a 'do not fill until' date.

  • Applies only to Schedule II substances.
  • Maximum total of 90-day supply.
  • Each additional prescription must specify a 'do not fill until' date.
  • All prescriptions must be written on the same day.

Memory trick: C-II M.P.: Multiple Prescriptions, Maximum 90 days.
