5.4 M.G.L. c. 94C, Massachusetts Schedules & Prescription Validity Windows

M.G.L. c. 94C, Massachusetts Schedules & Prescription Validity Windows

The Massachusetts Controlled Substances Act, M.G.L. c. 94C, runs in parallel with the federal Controlled Substances Act. Enforcement is shared between the DPH Drug Control Program and the Board of Registration in Pharmacy. Where the two systems differ, the more stringent rule governs — and in Massachusetts the state rule is usually the stricter one.

Six Schedules, Not Five

Schedules I through V track the federal criteria: abuse potential, accepted medical use, and dependence liability. Massachusetts then adds a sixth.

Schedule VI

Schedule VI comprises all prescription drugs that are required by federal or state law to be dispensed only on a prescription but which are not included in Schedules I through V. In practice, that is the entire ordinary legend drug catalogue: antihypertensives, statins, antibiotics, antidiabetics, inhalers, topical prescription products, and insulin.

Schedule VI is not a curiosity. It has four working consequences:

1. Registration. A practitioner needs an MCSR to prescribe ordinary legend drugs in Massachusetts.
2. Electronic prescribing. The state mandate reaches all Schedule VI prescriptions, so nearly every outpatient prescription must be issued electronically absent an exception.
3. Personnel scope. The technician tiers in 247 CMR 8.00 draw their boundary at Schedule VI: a certified pharmacy technician may take a new oral order or transfer a prescription for Schedule VI only.
4. Enforcement. Unauthorised possession, distribution or diversion of an ordinary legend drug is a controlled substance offence under state law.

[!IMPORTANT] Read "controlled substance" carefully in Massachusetts. Federal questions mean Schedules II–V. Massachusetts questions may mean II–VI. The PMP reporting rule, for example, reaches Schedules II–V plus the Schedule VI drug gabapentin — a distinction that only makes sense once Schedule VI is understood.

Prescription Validity and Refill Windows

This is one of the highest-yield tables in Massachusetts pharmacy law, and it comes from two different sources.

[!WARNING] Two traps here.

(1) Schedule V is not a one-year drug in Massachusetts. Federal law sets no refill ceiling for Schedule V and leaves it to the states; many study aids therefore guess "one year, refills as authorised." Massachusetts does not do that. Under 247 CMR 9.04, Schedule V sits with Schedules III and IV: six months, five refills. Only Schedule VI carries the one-year window.

(2) The 30-day Schedule II rule is in the statute, not the regulation. M.G.L. c. 94C, § 23 states that a written or electronic prescription for a Schedule II controlled substance becomes invalid 30 days after the date of issuance. There is no federal expiration date for a Schedule II prescription, so this is a pure Massachusetts overlay. A Schedule II prescription presented on day 31 cannot be filled in Massachusetts.

Counting from the right date

Every window above runs from the date of issuance — the date the practitioner wrote or transmitted the prescription — not from the date the patient first presented it and not from the date of the first fill. A Schedule III prescription issued on 3 January expires on 3 July even if the patient did not fill it until May, and even if refills remain.

    A[Prescription issued] --> B{Which schedule}
    B -->|Schedule II| C[Invalid after 30 days - no refills - c. 94C s. 23]
    B -->|Schedule III IV or V| D[No fill or refill after 6 months - max 5 refills - 247 CMR 9.04]
    B -->|Schedule VI| E[Valid 1 year from issue - 247 CMR 9.04]

Federal Overlay Worth Remembering

• Schedule II, federal: no refills (21 CFR 1306.12); no federal expiration date; sequential prescriptions up to a 90-day supply permitted with true issuance dates and "do not fill until" instructions.
• Schedules III and IV, federal: maximum five refills within six months of issuance (21 CFR 1306.22) — identical to the Massachusetts rule.
• Schedule V, federal: refills as authorised by the practitioner; Massachusetts is stricter.

When the two conflict, apply the stricter rule. When a question is silent about jurisdiction on a Massachusetts exam, apply Massachusetts law — NABP's own instruction is that candidates answer in terms of the prevailing laws of the state in which licensure is sought.

Worked Traps

• A Schedule V antitussive prescription written 8 months ago with 2 refills remaining. Expired in Massachusetts at six months. Do not dispense.
• A Schedule VI prescription for levothyroxine written 13 months ago marked "refill PRN." The one-year window has closed; a new prescription is required. "PRN" does not extend the statutory life of a prescription.
• A Schedule II prescription dated 35 days ago, never filled, with no "do not fill until" instruction. Invalid in Massachusetts under c. 94C, § 23, even though federal law would not bar it.
