I am all in favor of saving money. Everyone knows that living with diabetes presents challenges, not the least of which is expense. I have been reading posts on some blogs about people trying to extend the use of their insulin solutions (vials) longer than 28 days to save some money.
I have only one thought. It Is Not Worth It!
I have some information presented below. It is from the CDC website.
Questions about Multi-dose vials
- What is a multi-dose vial?
A multi-dose vial is a vial of liquid medication intended for parenteral administration (injection or infusion) that contains more than one dose of medication. Multi-dose vials are labeled as such by the manufacturer and typically contain an antimicrobial preservative to help prevent the growth of bacteria. The preservative has no effect on viruses and does not protect against contamination when healthcare personnel fail to follow safe injection practices.
- When should multi-dose vials be discarded?
Medication vials should always be discarded whenever sterility is compromised or questionable.
In addition, the United States Pharmacopeia (USP) General Chapter 797  recommends the following for multi-dose vials of sterile pharmaceuticals:
- If a multi-dose has been opened or accessed (e.g., needle-punctured) the vial should be dated and discarded within 28 days unless the manufacturer specifies a different (shorter or longer) date for that opened vial.
- If a multi-dose vial has not been opened or accessed (e.g., needle-punctured), it should be discarded according to the manufacturer’s expiration date.
The manufacturer’s expiration date refers to the date after which an unopened multi-dose vial should not be used. The beyond-use-date refers to the date after which an opened multi-dose vial should not be used. The beyond-use-date should never exceed the manufacturer’s original expiration date.
As a physician, I worked with multiple patients, and learned to be obsessive with patient safety and safe medication handling. As a patient responsible for your own medication administration, you need to be equally obsessive.
