15.4 Controlled-Substance Inventories and CT Perpetual CII
Key Takeaways
- Federal law requires an initial CS inventory when a registrant first handles controlled substances and a new inventory at least every two years (21 CFR 1304.11). Newly scheduled substances are inventoried on the effective date of scheduling.
- Opened containers: exact count or measure for Schedule II; estimated count for III–V unless the commercial container originally held more than 1,000 tablets or capsules, which then requires an exact count. Sealed, unopened commercial containers are taken at labeled quantity. Take the inventory at opening or close of business and write which one.
- CGS § 21a-254(h) also requires a complete annual inventory of all CS stocks, classically within four days of May 1 (date may shift if the registrant’s general physical inventory is not more than six months from that annual date), kept three years. That annual count is stricter than federal biennial.
- CGS § 20-633e (PA 18-16) requires every pharmacy and institutional pharmacy to maintain a perpetual inventory of each Schedule II substance, reconciled monthly, kept on the premises separate from other records, filed by date, three years. Electronic and ADC systems may satisfy the requirement if they keep an accurate real-time CII count. Perpetual CII does not apply to III–V and does not replace federal or annual inventories.
- Theft or significant loss: written notice to the DEA Field Division within one business day and a complete Form 106 within 45 days (21 CFR 1301.76(b)). Connecticut requires report of loss, theft, or unauthorized destruction to the Commissioner within 72 hours (CGS § 21a-262; RCSA § 21a-262-3; CGS § 20-633e(c) for perpetual discrepancies). For theft or in-transit loss, RCSA § 21a-262-3(b)(2) requires the signed statement to specify that local authorities were notified. DCP’s preferred path is DCP.DrugLoss@ct.gov.
Why the count on the clipboard is a scored overlay
Quick Answer: Take an initial inventory the day you first handle CS, then at least every two years (21 CFR 1304.11). Exact count of open CII; estimate open CIII–V unless the container originally held more than 1,000 tablets or capsules. Connecticut adds a complete annual CS inventory (CGS § 21a-254(h)) and a perpetual inventory of every Schedule II in pharmacies and institutional pharmacies, reconciled monthly (CGS § 20-633e / PA 18-16). Theft/significant loss: DEA Field Division within one business day, Form 106 within 45 days, DCP within 72 hours, and local authorities notified on theft (RCSA § 21a-262-3(b)(2)).
NABP 4.2.5 is inventories. Chapter 7.4 taught the federal engine and parked the perpetual-log workflow here. Do not treat perpetual CII as a substitute for biennial or annual complete counts. Do not put gabapentin on the CII perpetual log. Do not mash the 72-hour DCP theft clock into the 72-hour emergency oral CII covering-prescription clock from Chapter 7.3 — they are different duties.
Federal inventories — initial, biennial, opened versus sealed
21 CFR 1304.11(a) requires a complete and accurate record of all controlled substances on hand on the inventory date, in written, typewritten, or printed form at the registered location. Take the count at opening or close of business and write which one. Each registered location gets its own inventory. Zero CS on opening day is still an inventory: record the zero (1304.11(b)).
Biennial (1304.11(c)). After the initial count, take a new inventory of all CS at least every two years. Any date within two years of the previous biennial date is allowed; two years and a day is not. Newly scheduled substances (1304.11(d)) are inventoried on the effective date of scheduling, then rolled into later counts.
Opened versus sealed containers for dispensers:
- Sealed, unopened commercial containers — take the labeled quantity (name, finished form, units per container, number of containers). Do not break a seal merely to recount a factory bottle.
- Opened Schedule I or II — exact count or measure of the contents.
- Opened Schedule III, IV, or V — estimated count or measure, unless the commercial container originally held more than 1,000 tablets or capsules, in which case the count must be exact (21 CFR 1304.11).
An opened 100-count oxycodone bottle is counted tablet by tablet. An opened 100-count alprazolam bottle may be estimated. An opened 1,500-count CIII bulk bottle is counted exactly. Perpetual CII does not rewrite the III–V estimate rule.
Connecticut annual inventory — May 1, three years
CGS § 21a-254(h) requires a complete and accurate record of all stocks of controlled substances on hand, prepared annually within four days of May 1, except that a registrant may change this date if the general physical inventory date is not more than six months from that annual date. Keep it three years, on the premises, current, and separate from other business records. That annual complete CS count is stricter than federal biennial. A pharmacy that last did a full CS inventory 23 months ago may still be inside DEA’s two-year window and outside Connecticut’s annual window. More-restrictive wins. Aligning the federal biennial with the Connecticut annual (and with a monthly perpetual CII reconciliation) is lawful and sane; skipping the annual because “DEA is biennial” is not.
Perpetual inventory of all Schedule II — PA 18-16 / CGS § 20-633e
Public Act 18-16, § 5, codified at CGS § 20-633e (effective January 1, 2019), and DCP’s Perpetual Inventory page (updated April 28, 2025) require each pharmacy and institutional pharmacy to maintain a perpetual inventory of each Schedule II controlled substance designated under § 21a-243.
DCP’s working definitions:
- Pharmacy — a place of business where drugs and devices may be sold at retail under a § 20-594 pharmacy license.
- Institutional pharmacy — the pharmacy area in a care-giving institution or a correctional or juvenile training institution, under the direct charge of a pharmacist, where drugs are stored and dispensed (CGS § 20-571).
A perpetual inventory is an accurate, running count of all CII on hand. DCP states it may be electronic if it keeps an accurate real-time count and pharmacists on duty can access it for verification. An automated dispensing cabinet record system complies if it maintains an accurate CII record.
Monthly reconciliation (§ 20-633e(c)). At least once each month, compare the perpetual log with actual on-hand CII. DCP allows a cycle count to satisfy the requirement if it is done once each month and actually compares perpetual versus physical. In an ADC, a blind count can satisfy if the CII storage area is accessed at least once that month and the comparison occurs.
What the file looks like (§ 20-633e(d); DCP FAQ). Keep CII perpetual records on the premises, in an orderly manner separate from all other records, filed by date, not less than three years, and immediately available for inspection and copying by the Commissioner or persons authorized under § 21a-265.
What it is not. DCP’s FAQ is explicit: perpetual inventory and monthly reconciliation apply only to Schedule II. A pharmacy may adopt a stricter policy that includes III–V; the statute does not require it. Perpetual CII does not replace the federal initial/biennial inventory or the Connecticut annual complete CS inventory. Reconcile perpetual versus biennial/annual: if the monthly CII on-hand count and the complete inventory’s CII lines disagree, investigate before you sign either document. A 222 receipt that never hit the perpetual log is a receiving-failure, not a mystery shortage.
Theft, loss, and the Connecticut notification clock
Federal (21 CFR 1301.76(b)). For theft or significant loss of controlled substances:
- Notify the DEA Field Division in writing within one business day of discovery.
- File a complete DEA Form 106 through DEA’s secure network within 45 days of discovery.
Report even if the drugs are later recovered. “Significant” uses quantity, drug, person/process, pattern, diversion attractiveness, and local trends — not a magic tablet number. A sealed 100-count oxycodone missing from the CII safe is significant. Form 41 remains destruction, not theft.
Connecticut — 72 hours to the Commissioner. CGS § 21a-262 requires a registrant to report loss, destruction, or theft of controlled substances within 72 hours to the Commissioner of Consumer Protection. RCSA § 21a-262-3(b) repeats 72 hours of discovery and splits the statement:
- Breakage/accident other than in transit — signed statement of kinds, quantities, and circumstances, forwarded to the Commissioner, copy retained.
- Theft, or loss/destruction in transit — signed statement of the facts, an accurate listing of the CS stolen, lost, or destroyed, and a specification that local authorities were notified; copy retained. That is the verified local-law notice: the state packet for theft must say the local authorities were notified.
Perpetual-CII overlay (§ 20-633e(c)). Any loss, theft, or unauthorized destruction discovered during the monthly reconciliation is reported not later than 72 hours after discovery under § 21a-262 and RCSA § 21a-262-3. DCP’s preferred email is DCP.DrugLoss@ct.gov, and DCP’s FAQ also points to DEA Form 106. The 72-hour DCP clock is in addition to DEA’s one-business-day written notice. It is not a substitute for Form 106, and it is not the emergency oral CII 72-hour covering prescription.
| Event | Federal | Connecticut |
|---|---|---|
| Opening-day CS | Initial inventory, including a recorded zero | Same floor; keep 3 years |
| Recurring complete count | At least biennial | Annual complete CS inventory (21a-254(h)) plus perpetual CII |
| Open CII | Exact count | Exact, and the perpetual log must stay accurate |
| Open CIII–V | Estimate unless container originally >1,000 | Same count method; no statutory III–V perpetual |
| CII running count | Not federally required | Perpetual, monthly reconciliation (20-633e) |
| Theft / significant loss | Field Division 1 business day; Form 106 in 45 days | Commissioner 72 hours; theft statement notes local authorities notified |
Scenario: monthly short, annual due, local police called
A Norwalk community pharmacy reconciles perpetual CII on the last Sunday of the month and is short one sealed oxycodone 20 mg 100-count that Friday’s log still showed. Staff find no spill. That is theft or significant loss, not a Form 41 breakage. The pharmacist manager notifies the DEA New England Field Division in writing the next business day, files Form 106 through TLR inside 45 days, emails DCP.DrugLoss@ct.gov inside 72 hours, and notifies local police so the 21a-262-3(b)(2) statement can specify that local authorities were notified. The same month’s annual complete CS inventory (if this is the May window, or the pharmacy’s shifted general-inventory date) still exactly counts every open CII, estimates open CIV bottles under 1,000, and exactly counts a 1,200-count opened CIII. The perpetual CII page, the annual packet, the 106, and the DCP statement all stay on site three years. Treating the shortage as “we will catch it at the next biennial” fails § 20-633e the month it is found.
CT may be stricter; more-restrictive wins.

Which statement correctly describes Connecticut’s perpetual Schedule II inventory under CGS § 20-633e and DCP’s Perpetual Inventory page?
During a biennial inventory, a Connecticut pharmacy has an opened 80-count bottle of oxycodone 5 mg, an opened 90-count bottle of alprazolam 0.5 mg, and an opened commercial bottle of a Schedule III product that originally contained 1,200 tablets. How must those opened containers be counted?
On Tuesday a New Haven pharmacy discovers that a sealed bottle of morphine sulfate 15 mg is missing from the CII safe. No spill is found. Which reporting sequence is correct?
