We have a lot of single dose vials that we reuse during 6 hours window that is allowed per USP 797, since we serve pediatric patients, we usually do not use the whole vial per one patient.
I was wondering how other hospitals store vials in ISO 5 environment, since we might epinephrine vial and dexamethasone that look almost identical. Outside of ISO 5 environment we have more space, so we can segregate epinephrine vial away from dexamethasone. What about narcotics, since they have to be locked? How can we store open vials of narcotics safely in ISO 5 environment?
