Regulatory, Legal, and Professional Standards
Precision beats intuition
Legal items reward exactness. Identify which law governs, which form is required, and what the numerical limits are. Answer choices that feel permissive are usually wrong when a federal limit exists.
Concepts you must own
- The FDCA and Durham-Humphrey Amendment establish the prescription versus OTC distinction; the Combat Methamphetamine Epidemic Act restricts ephedrine and pseudoephedrine sales.
- Controlled Substances Act of 1970: schedules I–V, valid prescriber and patient requirements, and federal refill limits.
- Schedule II: no refills; multiple prescriptions may be issued for up to a 90-day supply with earliest-fill dates; an emergency oral order may be filled if a written prescription follows within 7 days; partial fills are limited to narrow situations such as emergency oral orders and long-term care or terminally ill patients.
- Schedule III–V: up to 5 refills within 6 months of issue, whichever comes first.
- Transfers: schedules III–V may be transferred, generally once, with some states permitting more; schedule II prescriptions are not transferable under federal law.
- OBRA '90: prospective drug utilization review and an offer to counsel, which the patient may decline.
- Also know HIPAA privacy, DSCSA, REMS, tamper-resistant prescription requirements, 503A versus 503B compounding, immunization authority, collaborative practice agreements, MedWatch reporting, and USP <800>.
- State boards of pharmacy add requirements; where state and federal rules differ, comply with both.
Traps
Recurring distractors are selecting Form 224 when 222 is intended, assuming federal law sets a prescription expiration date (it generally does not - states do), and forgetting that schedule II partial fills and transfers have only narrow exceptions.
Worked example
A prescriber writes 'oxycodone 5 mg, quantity 90, two refills.' The quantity is permissible but the refills are not: schedule II prescriptions cannot be refilled. The prescriber must issue new prescriptions and may issue three sequential 30-day prescriptions with 'do not fill before' dates to cover 90 days.
