Expiration dating of multidose vials
Tubersol and Aplisol multi-dose vials are good for 30 days after opening and will be dated upon opening.
Q: As a practicing consultant pharmacist to ambulatory surgery centers, I am often asked about the beyond use dating of medications drawn into syringes.However, if the expiration date of the vial is sooner than 28 days, then it expires on that date.Good practice is note the date first entered on the label.In general, multi-dose vials are good for 30 days after opening, however, in the interest of safety, the Student Health Center has decided that any multi-dose vial not excluded below will be discarded after one use.Certain medications may be discarded at a time-frame longer than 30 days if supported by documentation from the manufacturer.Multi-dose vials are designed for the administration of several doses for one patient.
If a multi-dose vial is used on more than one patient (for example: TB skin test solution and infl uenza vaccine ), the vial should not be kept or accessed in the immediate patient area, such as patient rooms or treatment rooms.
These medications are dispensed in vials, some of which are single use, others multi-dose.
Single dose vials are just that-medication for one-time-use on one patient.
She interpreted that to mean there were 100 units of Regular insulin in the small vial and began to draw up the patient’s dose…..
If you are a long-time nurse, especially in the correctional setting, you may be surprised to learn that drawing up insulin from multi-dose vials and mixing insulins in a single syringe are no longer as common a practice in traditional health care settings.
These medications may include but are not limited to: IPOL, Typhim VI, Pneumovax and Influenza Vaccine.
