Dating of multidose vials in hospitals
Shortages of some essential medications may warrant implementation of meticulously applied practice and quality standards to subdivide contents of single-dose/single-use vials, as stated in United States Pharmacopeia General Chapter ‹797› Pharmaceutical Compounding – Sterile Preparations.CDC is aware of a number of misinterpretations or misrepresentations of CDC’s guidelines regarding single-dose/single-use vials.For example, purified protein derivative, a tuberculosis test reagent, expires soon after use, Pate says.
Concerns have been raised about whether these guidelines and related policies contribute to drug shortages and increased medical costs to healthcare providers.
Therefore, CDC continues to strongly support its current policies regarding single-dose/single-use vials.
It is imperative that drug shortages and drug waste concerns are dealt with appropriately and do not lead to unsafe medical practices that impose increased disease risk on patients.
But some drugs last longer than 30 days, Pate says.
The drug may be used for more than 30 days after opening, but make sure it is stored properly and make a note of the expiration date.
