Federal Prescription Requirements — MPJE 2026

Valid prescription elements, refill rules by schedule, e-prescribing of controlled substances, corresponding responsibility, and transfer rules — essential MPJE knowledge.

Federal Prescription Requirements — MPJE Essentials

The MPJE tests your knowledge of what constitutes a valid prescription under federal law, the rules for refills, transfers, e-prescribing, and your corresponding responsibility as a pharmacist. These rules differ by drug schedule.

Required Elements of a Valid Prescription

ElementNon-CS RxCS Rx (CII-CV)
Patient name and address
Prescriber name, address, DEA#Name/address required; DEA# only if CS✅ All required
Drug name, strength, dosage form, quantity
Directions for use
Date issued
Prescriber signature✅ (manual for paper CII)
Number of refillsOptional (PRN allowed)CII = none; CIII-V = up to 5 in 6 months

Refill Rules by Schedule

Schedule II

No refills. New Rx required each time. Sequential dating allowed (up to 3 Rxs totaling 90 days).

Schedule III–V

Up to 5 refills within 6 months from date of issue. After 6 months or 5 refills (whichever comes first), new Rx needed.

Non-Controlled (Legend)

No federal limit on refills. State law may impose limits. Check your state regulations for specific refill and expiration rules.

E-Prescribing of Controlled Substances (EPCS)

  • Federal law PERMITS e-prescribing of all controlled substances including Schedule II (DEA Final Rule 2010)
  • Prescriber must use DEA-approved EPCS software with two-factor authentication
  • Pharmacy must use certified software to receive and archive electronic CS prescriptions
  • Many states now REQUIRE EPCS for all or most controlled substances — check your state's mandate

Corresponding Responsibility

Under 21 CFR 1306.04, a pharmacist has a corresponding responsibility to ensure that a controlled substance prescription was issued for a legitimate medical purpose by a practitioner acting in the usual course of professional practice. A pharmacist who fills a prescription knowing (or should have known) it is not for a legitimate medical purpose is just as guilty as the prescriber who issued it.

Prescription Transfers (Federal Rules)

  • Non-controlled Rx: Transferable between pharmacies (state rules apply)
  • CIII–CV Rx: May be transferred one time only between pharmacies — unless pharmacies share a real-time electronic database (then unlimited transfers)
  • CII Rx: Cannot be transferred — CII prescriptions are non-refillable and therefore non-transferable
