In many cases, the use of drugs and chemicals in laboratory animals requires that a mixture be made. For example, ketamine and xylazine are frequently used by being made into a solution for an injection into animals. Or, alternately, drugs may need to be diluted in sterile saline prior to use.
1. When making a mixture of drugs and/or chemicals in laboratory animals, documentation must be kept as to the identity of each individual drug/chemical used and their respective lot numbers and expiration dates.
2. Each mixture must be assigned an expiration date. The expiration date will be the shortest expiraion date of all drugs/chemicals used in the mixture OR 3 months, whichever is sooner.
3. A reminder, expired drugs or materials are not allowed for use in terminal procedures unless described and justified in the animal care and use protocol and approved by the IACUC.
