Controlled Substances Program

The UTMB Controlled Substances in Animal Research Program applies to all investigators and research personnel who purchase, possess, store, prepare, administer, transfer, document, or dispose of controlled substances used in activities involving live vertebrate animals under a UTMB IACUC-approved protocol.

This program does not apply to controlled substances used exclusively for in vitro research or for other activities that do not involve animals. 


Controlled Substances (CS) Accountability

  • DEA regulations require registrants to maintain complete and accurate records sufficient to account for all controlled substances received, administered or used, transferred, or disposed of.
  • To support compliance with these requirements, UTMB requires each original controlled substance stock bottle or container to be individually tracked from receipt through final disposition. A separate usage log must be initiated for each stock container, and every use must be documented when the activity occurs. The recorded balance must remain traceable and reconcilable with the quantity physically on hand.
  • Any dilution, mixture, or secondary preparation must be documented on a separate usage log and linked to the original stock container from which it was prepared.

In practical terms, each controlled substance container must remain fully traceable and reconcilable from receipt through final use, transfer, or disposal.

All records generated in connection with CSs must be kept at the registered location for at least two years and must be readily retrievable for inspection by the AWO, institutional officials, or authorized regulatory agencies.


  • DEA Researcher Registration Application

    Application: Diversion Control Division

    • New Application : Complete DEA Form 225:
    • Renewal Application : Complete DEA Form 225a 

    Hints for Completing DEA Form 225:

    • To be exempt from the application fee:
      • Check to the box CERTIFICATION FOR FEE EXEMPTION - Government Only and enter the UTMB Animal Welfare Office Director’s information:
        Certifying Official Name:    Gina F. Lungu
        Certifying Official Title:       Director, AWO
        Certifying Official Email:    gflungu@utmb.edu
        Certifying Official Phone:  (409) 266-3352

        Note: The Animal Welfare Office Director serves as the Certifying Official for fee exemptions related only to controlled substances used in animal research. Email the AWO office if you have any questions.
    • In Section 1, the “Point of Contact” should be the person to whom questions regarding the application should be directed.
    • Texas no longer issues state licenses for controlled substances. Enter all zeros for state license number on forms. Renewal forms will prepopulate the form with the previous state license number. Simply replace with all zeros. This is for researchers only.
    • Questions for DEA application should be directed to the Houston office: (800) 743-0595 or (713) 693-3660.
    • The DEA Investigator processing your application may request additional information after receiving your application.
    • Researcher registrations must be renewed every year.
    • The DEA will send an electronic reminder that renewal is due. The notice will go to the email address associated with the DEA registration. Renewal notices will no longer be sent by paper mail.
    • If a renewal application is submitted in a timely manner prior to expiration, the registrant may continue operations, authorized by the registration, beyond the expiration date until final action is taken on the application.
    • DEA allows the reinstatement of an expired registration for one calendar month after the expiration date. If the registration is not renewed within that calendar month, an application for a new DEA registration will be required.
    • Regardless of whether a registration is reinstated within the calendar month after expiration, federal law prohibits the handling of controlled substances for any period of time under an expired registration.

  • Forms and Associated Policies

  • Recordkeeping & Inventory

    General Recordkeeping Requirements

    NOTE

    • Inventories and records of all controlled substances listed in Schedules I and II must be maintained separately from all other records of the Registrant.
      • This also includes DEA Form 222. Unused, defective, or unexecuted DEA Forms 222 must not be discarded;
    • Inventories and records of Schedules III–V may be maintained either separately or in a manner that makes them readily retrievable from ordinary business records.

    Important Information related to the following topics:

  • Registrant-to-Registrant Transfer

    Transfer Between DEA Registrants

    Facilitate compliant transfers of controlled substances between authorized DEA-registered entities.

    ⚠ Transfer Restriction

    The 5% Rule: Researchers are limited to transferring 5% of their inventory per calendar year, with appropriate documentation (DEA Form 222 for Schedule II and invoices for Schedules III–V).

     21 CFR 1307.11 -- Distribution by dispenser to another practitioner.

     

  • Disposal of Controlled Substances

    Steps to dispose of unused or expired controlled substances.

    1. Request Disposal

    2. Schedule disposal

    • EPM will reach out and schedule the disposal/pick date and time. The DEA license holder and one member of the lab must be present.

    3. Day of Disposal

    Note: Keep each Disposal Records (EHS Chain of Custody and DEA Form 41)  for at least 2 years


  • Required Training

    All Registrants and Authorized Individuals working with controlled substances are required to complete UTMB's Use of Controlled Substances in Animal Research course in Learn 
  • Annual Controlled Substance Audit

    The AWO/IACUC will conduct inspections of DEA registrants utilizing CS in animal research at least annually.

    Inspections may be announced or unannounced and will include a review of storage and security, verification of authorized personnel records, and reconciliation of inventory documentation.

    Registrants must correct any identified deficiencies within 15 business days of notification.

    Failure to correct deficiencies will result in notification of the registrant’s Department Chair and Dean and may lead to additional disciplinary actions.

    What We Look for During an Audit

    • DEA Registration & Authorization : Confirm the DEA registration is current and that controlled substances are authorized for the registrant’s activities.
    • Records & Documentation: Review purchase/receipt records, transfer records, usage logs for each bottle, and inventory documentation. Verify appropriate documentation is maintained, including DEA Form 222s for applicable Schedule II transactions.
    • Inventory & Reconciliation: Conduct a physical inventory of controlled substances and reconcile the quantities on hand with purchase, transfer, usage logs, and disposal records, as applicable. Document any discrepancies.

      Storage & Security: Verify that controlled substances are stored securely and that access is limited to authorized personnel.

    • Expiration Dates: Check controlled substances for expiration dates and verify that expired substances are appropriately labeled and segregated.

    • Disposal Documentation: Review records for expired or unused controlled substances and verify that disposal is appropriately documented (maintain both EHS Chain of Custody and DEA Form 41)

    • Personnel & Access: Confirm that individuals handling controlled substances are appropriately authorized and completed the required training in Learn.

       

  • Ordering Controlled Substances
