6.4 Schedule V Non-Prescription (Exempt) Controlled Substances

6.4 Schedule V Non-Prescription (Exempt) Controlled Substances

The Critical Legal Distinction: Both federal law and Oklahoma law permit a pharmacist to dispense a narrow class of Schedule V preparations without a prescription. Oklahoma has not banned the practice. What Oklahoma has done is impose quantity ceilings expressed in milligrams of active narcotic, which bind well before the federal volume limits do, plus a pharmacist-only dispensing rule and a bound record book. This is a classic Oklahoma MPJE trap: candidates who memorize "my state bans OTC Schedule V" get it wrong, and candidates who memorize only the federal ounce limits also get it wrong.

1. Federal CSA Baseline: 21 CFR § 1306.26

Under 21 CFR § 1306.26, a Schedule V controlled substance that is not a prescription drug as determined under the Federal Food, Drug, and Cosmetic Act may be dispensed by a pharmacy without a prescription, provided all of the following are met:

1. The dispensing is made by a pharmacist (a non-pharmacist employee may complete the actual cash or credit transaction, but only after the pharmacist has discharged the professional and legal responsibilities).
2. Not more than 240 mL (8 fl oz) or 48 dosage units of any substance containing opium, and not more than 120 mL (4 fl oz) or 24 dosage units of any other Schedule V substance, may be dispensed to the same purchaser in any 48-hour period.
3. The purchaser is at least 18 years old.
4. The pharmacist requires suitable identification (including proof of age) from any purchaser not known to them.
5. A bound record book is maintained containing the purchaser's name and address, the name and quantity of the substance, the date of each purchase, and the name or initials of the dispensing pharmacist.

Typical products: low-dose codeine antitussive syrups and diphenoxylate/atropine-type antidiarrheals — when marketed as non-prescription products.

2. Oklahoma's Overlay: OAC 475:30-1-14 & 63 O.S. § 2-313

The Oklahoma Bureau of Narcotics and Dangerous Drugs Control (OBNDD) rule OAC 475:30-1-14 opens with the same permission:

"A controlled dangerous substance listed in Schedule V which is not a prescription drug as determined by the Oklahoma State Board of Pharmacy and/or the Federal Food and Drug Administration, may be dispensed by a pharmacy without a prescription to a purchaser at retail level; PROVIDED that..."

The Oklahoma "provided that" list is where the state diverges:

Two additional Oklahoma conditions carry real exam weight:

• Non-narcotic active ingredient required. The preparation must contain, in addition to the narcotic, "some drug or drugs conferring upon it medicinal qualities other than those possessed by the narcotic drug alone," and must be dispensed in good faith as a medicine and not to evade the Uniform Controlled Dangerous Substances Act. A pharmacist who recognizes that a purchaser is buying the product for its narcotic content alone has an independent duty to refuse.
• Per-single-preparation caps. OAC 475:30-1-14(3)(A) carves out preparations containing, per 30 mL (or per one avoirdupois ounce if solid/semi-solid), not more than 160 mg opium, 20 mg morphine or its salts, or 80 mg codeine or its salts. Paragraph (C) separately addresses preparations containing not more than one drachma of paregoric per 30 mL, and paragraph (B) covers external-use-only liniments and ointments (excluding anything containing coca leaves in any quantity).

3. Working the Arithmetic

The Oklahoma exam tests the milligram ceiling, not the ounce ceiling, because the milligram ceiling is what binds.

Worked example. A patient known to the pharmacist, age 34, asks to purchase a non-prescription codeine antitussive containing 10 mg codeine phosphate per 5 mL. How much may the pharmacist dispense in a 48-hour period under Oklahoma law?

$\frac{160\text{ mg codeine (OK 48-hour cap)}}{10\text{ mg per 5 mL}} = 16 \text{ units of 5 mL} = 80\text{ mL}$

Oklahoma's cap is therefore 80 mL in 48 hours. The federal rule would have permitted 120 mL of this non-opium Schedule V product. Under the Stricter Standard Rule, Oklahoma's 80 mL governs. A candidate who reached for "4 fluid ounces" would over-dispense by 40 mL and violate state law.

Second scenario. The same patient returns 20 hours later and asks for a different exempted Schedule V preparation. Oklahoma bars this outright: the rule permits no more than one § 2-313 exempted preparation to the same person within any 48 consecutive hours, independent of the milligram math.

4. What the Exemption Does Not Cover

• Schedule V prescription drugs. The exemption is limited by its own terms to a Schedule V CDS "which is not a prescription drug." Pregabalin (Lyrica) is a Schedule V CDS but is an FDA prescription-only drug — it can never be sold under this exemption and always requires a valid prescription, which in Oklahoma must be transmitted electronically under 63 O.S. § 2-309 unless an exception applies.
• Schedules II–IV. Nothing in Schedules II, III, or IV may ever be dispensed without a prescription at retail. Only Schedule V non-prescription preparations qualify.
• Distributor or non-pharmacy retail sale. The permission runs to a pharmacy acting through a CDS-licensed pharmacist. A convenience store or a pharmacy clerk acting alone cannot make the sale.
• The PMP question. Because these are dispensed without a prescription rather than pursuant to one, they are handled through the bound record book rather than the prescription-based PMP transmission that 63 O.S. § 2-309D imposes on CDS "dispensed pursuant to a valid prescription." Do not confuse the record book with the PMP.

5. Exam Strategy

When an Oklahoma MPJE item presents a non-prescription Schedule V scenario, run this order:

1. Is the product a prescription drug? If yes, stop — a prescription is required.
2. Is the purchaser at least 18, and identified? If not, refuse.
3. Is a pharmacist making the dispensing decision? A technician or clerk cannot.
4. Apply the Oklahoma milligram ceiling (320 mg opium / 40 mg morphine / 160 mg codeine per 48 hours), not the federal volume ceiling.
5. Has the purchaser already received an exempted preparation within 48 hours? If yes, refuse — only one is permitted.
6. Record the sale in the bound record book and label per 63 O.S. § 2-314(B).
