Revised Policies, Guidelines Clarify Expectations for the Use of Expired Drugs and Medical Materials in Animals
We know that you rely on us – your Animal Care & Use Program partners – to provide the tools and resources necessary for safeguarding animal welfare while conducting sound scientific research.
While it is clear that the administration and/or use of expired drugs and other substances can endanger animal health and compromise the validity of your results, navigating the many nuanced requirements for the proper management, storage, and maintenance of these materials may be challenging and, at times, confusing.
After extensive fact-finding and assessment, our Institutional Animal Care & Use Committee (IACUC) has approved several revisions to existing policies and guidelines to more clearly articulate programmatic expectations for the appropriate storage, labeling, and use of expired drugs and other medical materials in animal activities.
We ask that all individuals who handle or work with animals as part of their research operations review the following documents carefully to ensure that they understand their individual roles and responsibilities:
- Policy on the Use, Storage, and Expiration of Substances, Agents, and Medical Materials Used in Animals
- Guidelines on the Preparation of Injectable Substances and Agents Administered to Animals
For convenience, key policy and guideline changes are also summarized below in order of their potential impact(s) on daily research activities. All changes are effective immediately.
