7.1 When PA Law Is Stricter Than Federal Law

The Stricter-Standard Rule

The MPJE tests whether you know which law controls when Pennsylvania and federal pharmacy law overlap. The governing rule is straightforward: the more restrictive standard always controls, and the less restrictive law does not displace it. Federal law sets a floor — states may exceed it but cannot weaken it. On the PA MPJE, when a fact pattern asks what a pharmacist must do under Pennsylvania law and the PA rule is stricter than the federal rule, the PA rule is the correct answer.

This rule comes from the Supremacy Clause's preemption doctrine: federal law preempts state law only when (1) Congress expressly says so, (2) federal law occupies the entire field, or (3) state law conflicts with federal law such that compliance with both is impossible. Pharmacy is a health-and-safety area traditionally regulated by the states, so most state pharmacy rules are not preempted. PA's stricter rules — counseling, immunization age, PDMP, e-prescribing, opioid limits, supervision — all survive because they do not conflict with federal law; they add requirements on top of it.

How to Decide Which Controls on the Exam

Use this three-step decision tree on every MPJE question:

1. Read the call of the question. Is it asking about federal law, PA law, or both? Trigger words: "under Pennsylvania law," "under federal law," "under PA and federal law," "which is true in this jurisdiction."
2. Identify the rule on both sides. Recall the federal floor and the PA ceiling.
3. Apply the stricter standard. If PA is stricter than federal, the PA rule governs the action the pharmacist must take. If the question asks what is permitted (not required), the more permissive federal rule may still apply, but the PA restrictions on that permission still bind.

Side-by-Side PA vs Federal Scenarios

Scenario A — Counseling Offer

A pharmacist dispenses a new prescription for an antibiotic to a privately insured adult. Under OBRA '90, the federal floor requires a prospective drug utilization review (DUR) and an offer to counsel only for Medicaid outpatients. Federal law is silent on counseling offers for non-Medicaid patients. PA's 49 Pa. Code § 27.18 requires the pharmacist (or pharmacist-intern under supervision) to offer to counsel on every new prescription, regardless of payer. The correct MPJE answer: the pharmacist must offer counseling to the private-pay patient. Picking the federal-only answer ("OBRA covers only Medicaid, so no offer is required") is the trap.

Scenario B — Immunization Age

A pharmacy intern wants to administer a flu shot to a 6-year-old. Federal PREP Act immunity covers pharmacists acting as covered countermeasures administrators, but does not itself grant practice authority — that comes from state law. PA 49 Pa. Code § 27.403(a) allows pharmacists and interns to administer injectable medications, biologicals, and immunizations to patients 8 years of age or older (amended effective April 11, 2026, lowering the age from 18 to 8). Under § 27.403(b), influenza and COVID-19 immunizations may be given to patients 5 years of age or older. Interns must act under the direct and immediate personal supervision of an authorized pharmacist. The correct answer for a 6-year-old flu shot: it is permitted because flu/COVID is allowed at 5+, not because PREP Act preempts the PA age floor.

Scenario C — PDMP Query Triggers

Pennsylvania dispenser PDMP queries apply before opioid/benzodiazepine dispensing when new-patient, cash-pay, early-refill, or multi-prescriber triggers are present (Act 191 as amended) — a PA-specific operational duty layered on federal corresponding responsibility.

Scenario D — E-Prescribing Mandate

Federal EPCS under 21 CFR Part 1311 permits but does not require electronic prescribing of controlled substances. PA, effective October 24, 2019 under Act 96 of 2018, mandates electronic prescribing for all CII–CV controlled substances (with narrow exceptions). The correct answer: a paper CII prescription is generally invalid in PA even if it would satisfy federal rules. Do not be misled by outdated guidance suggesting PA only permits e-prescribing — PA mandates it.

Scenario E — Technician Supervision

Federal law imposes no pharmacist-to-technician ratio. PA's final rulemaking (effective June 28, 2025, 55 Pa.B. 4335) also imposes no fixed numeric ratio; the proposed 1:2 ratio was deleted. The pharmacist must provide direct and immediate personal supervision, and the pharmacist-manager must maintain a written protocol for each technician under 49 Pa. Code § 27.12. Technicians and trainees must be registered with the Board. The correct answer: supervision is qualitative, not a numeric cap.

Scenario F — Act 122 and Act 125 7-Day Opioid Limits

Federal law has no general 7-day opioid limit. PA's Act 122 of 2016 (Safe Emergency Prescribing Act) limited opioids prescribed in an ED, urgent care, or hospital observation setting to a 7-day supply with no refills, effective Jan 1, 2017. Act 125 of 2016 (effective Feb 4, 2017) limits opioid prescriptions for minors (under 18, emancipated minors excepted) to 7 days with written parent/guardian consent, or a single 72-hour supply with an authorized adult's consent. Act 112 of 2019 (effective Nov 27, 2019) requires prescribers to establish an opioid treatment agreement before issuing the first opioid prescription for chronic pain (not an acute-pain 7-day cap). Exceptions to the 7-day limits: cancer, palliative/hospice, chronic pain (with Act 112 treatment agreement), and major surgical (documented). The correct answer on an ED opioid discharge for an adult is 7 days, no refills.

Scenario G — Collaborative Practice Agreements

Federal law does not regulate collaborative practice. PA's 49 Pa. Code § 27.302 authorizes a collaborative agreement for management of drug therapy in a non-institutional setting. The agreement must be between a physician and a pharmacist, in writing, identify the parties, be voluntary, and be initiated on a written referral from the physician. CRNP collaborative agreements live at 49 Pa. Code § 21.285 and are not within pharmacist scope. The correct answer requires the written physician-pharmacist agreement plus the written referral.

Table of PA-Stricter Examples

Common Traps

• Trap 1 — Federal-only answer. The stem says "under Pennsylvania law" but the distractors recite a correct federal rule that is not the controlling one. Always check whether PA adds a stricter duty.
• Trap 2 — Preemption overreach. Federal law preempts state law only on express, field, or conflict grounds. Pharmacy is not a field-preempted area; do not assume federal law displaces PA rules.
• Trap 3 — More-restrictive vs more-permissive confusion. "Permitted federally" does not mean "permitted in PA." PA's restrictions still bind.
• Trap 4 — Mirroring another state. PA does not mirror NY, OH, or NJ. Do not import another state's ratios, age cutoffs, or PDMP triggers.
• Trap 5 — Outdated values. Use the newest applicable rule: immunization age 8 (not 18); no technician ratio (not 1:2); e-prescribing mandatory (not permissive).

The throughline: when PA is stricter, PA controls; when federal is stricter, federal controls; and on the MPJE, the call of the question tells you which body of law is being tested.
