5 Inventory, Records, and Disposal

Account for controlled substances

Controlled-substance compliance requires being able to account for drugs from receipt through dispensing, transfer, or disposal. Federal DEA rules establish minimum requirements, while state law may require longer record retention or additional documentation.

Establish and record inventories

A registrant must take an Initial inventory when first engaging in activities that require controlled-substance records, then take a new inventory at least every two years. A zero-stock initial inventory must also be recorded. Inventory applies to each registered location and applicable independent activity.

Record the inventory date, whether the count was taken at the opening or close of business, and the controlled substances on hand. For each drug, record its strength and dosage form, container size, number of containers, and total quantity.

Count and describe stock

The required counting method depends on the drug’s schedule. Schedule I and II drugs require an actual Physical count. For Schedules III–V, an estimate is generally permitted, except that containers holding more than 1,000 tablets or capsules require an exact count.

An inventory entry should make the quantity understandable from its details. For example, it might specify a drug’s strength and form, 100 tablets per bottle, three sealed bottles, and the total count.

Record transactions and retain documents

Registrants must keep a complete, accurate, and current record of controlled substances received, sold, delivered, transferred, or otherwise disposed of. Federal rules do not require a perpetual inventory, but Transaction records should make it possible to explain changes in stock.

Typical pharmacy records include invoices or receipts, required order forms, dispensing records, inventories, transfer records, and disposal documentation. Record transactions as they occur and preserve the connection between supporting documents and the inventory ledger.

Retain and organize records

Keep required records and inventories for at least two years, and make them available for inspection by authorized DEA personnel. State requirements may extend the retention period. Electronic records should be searchable, readable, and producible for inspection.

Schedule II inventory and records must be kept separately from other pharmacy records. Schedule III–V records may be kept separately or in a format that makes them readily retrievable.

Reconcile stock and investigate discrepancies

A sound compliance process regularly compares physical stock with receipts, dispensing or administration records, transfers, returns, and disposal records. This Reconciliation helps account for changes in stock. DEA rules establish inventory and recordkeeping duties; the organization and any applicable state requirements should determine the frequency of routine reconciliation and other internal controls.

When a count does not match the records, promptly recount and review source documents, date ranges, returns, voids, adjustments, and access logs. Document the discrepancy, investigation, explanation if known, and corrective action in a dated, attributable audit trail. Do not silently alter or overwrite the original entry.

Respond to theft or significant loss

DEA guidance distinguishes clerical miscounts from theft or significant loss. Document a clerical correction internally; an adjustment to a count alone does not require reporting on DEA Form 106.

If theft or a Significant loss is suspected, notify the local DEA Field Division in writing within one business day of discovery and submit a complete DEA Form 106 within 45 days. Assess whether a loss is significant using factors such as the quantity, drug involved, access, patterns of loss, and diversion risk.

Use authorized disposal routes

Controlled substances held in a registrant’s inventory must be disposed of through an authorized route. Examples include prompt on-site destruction under applicable rules, transfer to a registered Reverse distributor, or an authorized return or recall. Registrant inventory is not disposed of through a public take-back receptacle.

Destruction must comply with applicable federal, state, tribal, and local requirements and render the substance non-retrievable. Document the actual transfer or destruction date and the drug and quantity involved.

Document transfers and destruction

For a pharmacy transfer of Schedule III–V stock to a reverse distributor, the pharmacy keeps a record of the distribution. Schedule II transfers are subject to required order-form rules. The reverse distributor generally records its destruction on DEA Form 41.

A registrant that destroys inventory itself, or causes destruction under the applicable regulation, must document destruction on Form 41, including required witness information. Form 41 documents destruction, not the pharmacy’s transfer to a reverse distributor. Keep transfer receipts, destruction confirmations, and required forms with the relevant records.

Make records traceable

Good records are made at the time of the event and identify who performed or verified it. Corrections should remain traceable, and supporting documents should stay connected to the inventory ledger. A clear record lets a reviewer follow the drug’s movement without relying on memory or unexplained adjustments.

In practice, maintain an accurate initial and biennial inventory, record transactions as they occur, retain records for at least two years or longer if state law requires, investigate and document discrepancies, report theft or significant loss on time, and use authorized disposal methods with the required transfer and destruction records.
