How long may sterile plastic caps, syringes, or devices be stored in a class 5 environment after being opened?
These supplies and devices should only be opened just prior to use. Any opened packages need to be protected from touch contamination and must be stored in “first-air” and within the ISO Class 5 air at all times. The USP Chapter does not stipulate this time and it is responsibility of the compounder to ensure the sterility of any supply or device used when compounding CSPs.
