Question of the Week

The federal floor is at least 2 years from the date of the inventory or record, and they must be available for inspection and copying by authorized DEA employees. State law very often requires longer — five years is common — and where the two differ, the longer period governs what you actually do. The exam wants the federal number unless it tells you otherwise. Where records are kept is a separate question with its own rules: executed order forms and inventories must be maintained at each registered location, while certain financial and shipping records may be held centrally after notice to DEA.

21 C.F.R. § 1304.04(a)

Answering with your own state's retention period, or assuming the two-year rule also settles where the records have to sit.

Inventories and records of Schedule I and II substances must be maintained separately from all other records of the pharmacy. Schedule III, IV and V records get a choice: separately, or in a form in which the required information is readily retrievable from ordinary business records. The asymmetry is the whole question — Schedule II has no readily-retrievable option. Note the rule treats inventories and records separately from paper prescription files, which have their own paragraph and carry the red “C” stamp and its waiver.

21 C.F.R. § 1304.04(h)(1) and (h)(3)

Extending the readily-retrievable allowance up into Schedule II. It stops at Schedule III.

On the effective date of the rule adding the substance to a schedule, every registrant required to keep records who possesses it must take an inventory of all stocks of that substance on hand. This record then sits alongside the initial and biennial inventories. Waiting for the next biennial could leave the substance uncounted for up to two years, which is the gap the rule closes. One limit worth holding onto: this triggers only where the substance was not previously listed on any schedule — moving a drug between schedules does not set it off.

21 C.F.R. § 1304.11(d)

Assuming the biennial cycle is the only inventory trigger — or over-applying this one to reschedulings, which it does not reach.

The inventory may be taken either as of the opening of business or as of the close of business on the inventory date, and it must be indicated on the inventory. It is a small formality that sinks a lot of otherwise careful counts: a dated inventory with no opening/close designation is an incomplete record, and an inspector will record it as one.

21 C.F.R. § 1304.11(a)

Treating the date as sufficient. The regulation wants the date and the point in the business day, written down.

For a container that has been opened: if the substance is in Schedule I or II, make an exact count or measure. If it is in Schedule III, IV or V, an estimated count will do — unless the container holds more than 1,000 tablets or capsules, in which case the exact count comes back. Sealed, unopened commercial containers are not opened to be counted at all: you record the units per container and the number of containers.

21 C.F.R. § 1304.11(e)(6)(i)–(ii)

Remembering “estimate below Schedule II” and forgetting the 1,000-unit exception sitting inside it.
