PTCB Certified Pharmacy Technician (PTCE)Federal RequirementsHard

A pharmacy technician receives a prescription for clobazam, a Schedule IV controlled substance. The patient is requesting a transfer to another pharmacy. According to federal regulations, how many times can a prescription for clobazam be transferred between pharmacies?

  1. AOne time
  2. BAs many times as there are refills remaining
  3. CUnlimited times within the validity period
  4. DZero times
Show answer & explanation

Correct answer: A. One time

Federal law dictates that prescriptions for Schedule III, IV, and V controlled substances may be transferred only one time between pharmacies for refill purposes. If pharmacies share a common electronic database, they may transfer up to the maximum number of refills permitted by law and the prescriber.

Why the other options are wrong

  • B. This is only true if the pharmacies share a common electronic database. Without that specific condition, the general rule is one transfer.
  • C. Incorrect; there are strict limits on controlled substance transfers.
  • D. Incorrect; CIII-V prescriptions can be transferred, unlike C-IIs.

CIII-V Prescription Transfers

Federal law allows prescriptions for Schedule III, IV, and V controlled substances to be transferred once between pharmacies, unless they share a common electronic database, in which case they can be transferred up to the number of refills authorized.

  • C-IIs cannot be transferred.
  • CIII-V can be transferred once to another pharmacy.
  • If pharmacies share a common electronic database, multiple transfers are allowed up to the number of refills.
  • Transfer must be communicated directly between pharmacists.

Memory trick: C3-5: One transfer, unless you're a Twin (common database).
