Receiving, Ordering & Destroying Controlled Substances
Federal requirements for receiving, storing, ordering, labeling, dispensing, returning, take-back programs for, loss or theft of, and destroying controlled substances.
Receiving, Ordering & Destroying Controlled Substances is worth 3.2% of the PTCE inside the Federal Requirements domain (18.75% overall). It tests the paperwork and procedures that move a controlled substance through the pharmacy: ordering, receiving, inventory, returns, take-back, loss/theft reporting, and destruction. The unifying idea is an unbroken chain of accountable records — every Schedule II unit must be traceable from the moment it is ordered to the moment it leaves.
Ordering Schedule II Drugs — DEA Form 222 and CSOS
Schedule I and II controlled substances may be ordered only with a DEA Form 222 (the single-sheet form since 2019) or its electronic equivalent through the Controlled Substance Ordering System (CSOS). The purchaser keeps a copy and the supplier retains the original, and both parties keep the record for at least 2 years. Schedules III, IV, and V do not require a 222 or CSOS order but must still be documented on the invoice or packing slip. When Schedule II stock is received, the pharmacy records the date and quantity received against the order.
DEA Form 222 (or CSOS) is required to order Schedule I and II drugs — Schedules III–V use an invoice.
Inventory Requirements — 21 CFR 1304.11
A registrant takes an initial inventory of all controlled substances on hand when first dispensing, then a new inventory at least every 2 years — a biennial inventory, which is the federal minimum. Schedule I and II substances always require an exact count. Schedule III, IV, and V substances may be estimated in an opened container, unless that opened container holds more than 1,000 tablets or capsules, in which case an exact count is required — an unopened, factory-sealed container can be counted by the number of containers rather than opened and hand-counted. Records are kept at the registered location; Schedule II records must be maintained separately from all other records.
The federal minimum is a biennial (every-two-year) inventory — not a perpetual/running count.
Loss, Theft, and Reporting
A significant loss or theft of controlled substances must be reported to the local DEA Diversion Field Office in writing within 1 business day of discovery, followed by a completed DEA Form 106 documenting the extent of the loss (the 2023 final rule set a 45-day follow-up window and moved Form 106 to electronic submission). Form 106 captures the name, quantity, and circumstances of the loss. A single-tablet counting discrepancy is not automatically a "significant loss," but genuine theft always is.
Theft or significant loss: notify DEA in writing within 1 business day, then file DEA Form 106.
Returns, Take-Back, and Destruction
Returning Schedule II stock to a supplier or reverse distributor requires a DEA Form 222 from the receiving registrant, mirroring the ordering process. Pharmacy stock destined for destruction is recorded on DEA Form 41 and destroyed to the "non-retrievable" standard, usually via a reverse distributor. For patient (ultimate-user) drugs, the DEA's 2014 disposal rule created three voluntary take-back options — take-back events, mail-back programs, and collection receptacles — and lets retail pharmacies and other registrants become authorized collectors. Substances collected from patients may never be counted, sold, or returned to stock.

Start Receiving, Ordering & Destroying Controlled Substances Practice Quiz →Key Concepts — Part 1
1. Which DEA form must a pharmacy use to order Schedule II controlled substances from a wholesaler?
DEA Form 222, or its electronic CSOS equivalent
DEA Form 222, or the electronic Controlled Substance Ordering System (CSOS) equivalent, is required to order Schedule I and II drugs. Form 224 (A) is the pharmacy's registration application, Form 106 (C) reports theft or loss, and Form 41 (B) documents destruction.
2. Which schedules of controlled substances require a DEA Form 222 or CSOS order for purchasing?
Schedules I and II only
Form 222/CSOS is required specifically for ordering Schedule I and II substances. Schedule III-V drugs are ordered through regular wholesaler purchasing and invoicing without Form 222, making B and C incorrect; D is incorrect because Schedule I registrants, such as researchers, also use the form.
3. Who is authorized to sign a DEA Form 222 on behalf of a pharmacy?
The registrant, such as an authorized pharmacist, or someone holding valid power of attorney from the registrant
Only the registrant or an individual holding valid, DEA-recognized power of attorney may sign Form 222. A technician (A) cannot sign it, nor can the delivery driver (B); after-the-fact verification by a manager (D) does not satisfy the signature requirement.
4. When a Schedule II shipment arrives at the pharmacy after being ordered via Form 222, what should happen upon receipt?
The pharmacist should verify the contents received against the Form 222 order and document any discrepancies
Upon receipt, the pharmacist or other authorized registrant must verify the actual quantities received against what was ordered on Form 222 and record any discrepancies. Simply stocking without verification (A) or trusting the wholesaler blindly (D) fails this duty, and forwarding an unopened, legitimately ordered shipment to a reverse distributor (C) makes no sense.
5. A pharmacy discovers a significant, unexplained shortage of oxycodone tablets. What must be filed with the DEA, and within what timeframe from discovery?
DEA Form 106, within 1 business day of discovery
A significant loss or theft of controlled substances must be reported to the DEA using Form 106 within one business day of discovery. Form 224 (A) is for registration and Form 41 (C) is for destruction, neither applies here; D is incorrect because federal reporting to the DEA is required regardless of separate police notification.
6. Besides filing DEA Form 106, what else should a pharmacy typically do when it discovers a theft of controlled substances?
Notify local law enforcement of the theft
In addition to DEA reporting, pharmacies typically notify local law enforcement about a theft. Waiting for the next inventory (A) delays appropriate response, destroying remaining stock (C) is not an appropriate reaction to theft, and D understates the pharmacy's practical obligations.
7. What factors help determine whether a controlled substance loss is significant and therefore reportable to the DEA?
The quantity lost, whether a pattern of losses exists, the type of drug, and whether the loss can be reasonably explained through normal recordkeeping
DEA guidance considers multiple factors, including quantity, patterns over time, drug type and abuse potential, and whether the loss can be reasonably accounted for, not a single factor like dollar value (A), day of the week (B), or a patient complaint (D).
8. How must Schedule III, IV, and V drugs typically be ordered from a wholesaler, in contrast to Schedule II drugs?
They may be ordered through standard purchase orders and invoices without Form 222, but the resulting records must remain readily retrievable
Unlike Schedule II drugs, Schedule III-V drugs are ordered via ordinary purchasing documentation rather than Form 222, though the resulting records must still be readily retrievable for DEA inspection. A incorrectly extends the Form 222 requirement, B is false since these drugs are routinely stocked, and D misstates registration requirements.
9. Federal law requires that labels for dispensed Schedule II-V prescriptions include which of the following?
A statement warning that federal law prohibits transfer of the drug to any person other than the patient for whom it was prescribed
Controlled substance labels must include a federal transfer-prohibition warning. A pharmacist's personal phone number (A), wholesaler information (C), and red-ink NDC printing (D) are not federal labeling requirements.
10. How long must a pharmacy retain controlled substance records, such as Form 222 copies, invoices, and dispensing records, under federal law?
2 years
Federal law requires controlled substance records to be retained for a minimum of 2 years, though some states require longer. 6 months (A) and 1 year (B) are too short, and 10 years (D) exceeds the federal minimum.
Key Concepts — Part 2
1. What is power of attorney in the context of DEA Form 222 or CSOS ordering?
A document by which a registrant authorizes another individual to sign controlled substance order forms on the registrant's behalf, which the registrant may revoke at any time
Power of attorney in this context lets a registrant delegate signing authority for order forms to another person, revocable whenever the registrant chooses. It is unrelated to patient guardianship (A), caregiver designation (C), or independent technician counseling authority (D).
2. How often must a pharmacy renew its DEA registration?
Every 3 years
DEA registrations for pharmacies must be renewed every 3 years. Annual renewal (A) and 5-year cycles (B) do not match the federal schedule, and D is incorrect since registrations do expire and require renewal.
3. A technician performing a routine controlled substance count discovers what appears to be a shortage of hydrocodone tablets. What is the most appropriate immediate action?
Report the discrepancy to the pharmacist-in-charge right away so it can be properly investigated
Any suspected shortage must be reported to the pharmacist-in-charge for proper investigation and potential DEA reporting. Quietly altering records (A) is falsification, assuming error without verification (C) risks missing real diversion, and destroying stock (D) is not an appropriate or authorized response to a suspected shortage.
4. A wholesaler delivery of Schedule II medication arrives at the pharmacy, but the pharmacist is temporarily off the floor. What is the appropriate handling?
The delivery should be accepted, secured, and verified by an authorized, appropriately credentialed individual as soon as possible, and should never be left unsecured or accessible to unauthorized persons
Controlled substance shipments must be handled securely by authorized personnel and properly verified, even if there's a brief delay; they should never be left unsecured or unattended. A allows unauthorized handling, C creates a security risk, and D is an overly rigid response when secure handling by other authorized staff may be appropriate.
5. A pharmacy wants to return outdated, unopened Schedule III bottles to the manufacturer for credit. What is the appropriate federally compliant channel?
Use a DEA-registered reverse distributor or another mechanism that complies with controlled substance return and recordkeeping requirements
Returns of outdated controlled substance stock must go through a DEA-registered reverse distributor or otherwise comply with controlled substance handling and documentation rules, not standard uncontrolled shipping (A), general trash disposal (C), or a recycling center (B).
6. Which of the following would most likely trigger a review of a pharmacy's controlled substance ordering pattern by the DEA or a wholesaler?
A sudden, unexplained spike in Schedule II ordering volume that is disproportionate to the pharmacy's typical dispensing history
Wholesalers and the DEA monitor for suspicious ordering patterns, such as unexplained spikes in controlled substance orders inconsistent with a pharmacy's dispensing history, as a potential diversion red flag. Routine non-controlled ordering (A), seasonal Schedule V fluctuation (C), and a one-time wholesaler switch (D) are not inherently suspicious.
