For how long must controlled drug records be kept after the date of the last entry?

• A. 1 year
• B. 2 years
• C. 5 years
• D. 10 years

Answer: (B)

The main idea here is how long authorities expect you to keep controlled drug records after the last entry to ensure traceability and allow for audits or investigations. The required period is two years. From the date of the most recent entry, you keep the records for two years to cover any reconciliation or regulatory checks that might arise. For example, if the last entry was on 1 January 2024, you would retain the records until 1 January 2026. This two-year window balances the need for accountability with practical storage considerations. Longer periods aren’t typically required for these records and shorter periods could leave you unprepared for any review or inquiry.
