Which time frame is mentioned for using Xopenex Nebulizer vials after removal from the pouch?

The proper time frame for using Xopenex Nebulizer vials after removal from their pouch is one week, which means they should be used within seven days. This guideline is crucial for ensuring the effectiveness and safety of the medication, as exposure to air can lead to changes in chemical composition and potency.

Adhering to such time limits is standard practice for many nebulized medications, which underscores the importance of following the manufacturer's recommendations for storage and usage.
