What is the Beyond Use Date (BUD) for Multi Use Vials?

The Beyond Use Date (BUD) for multi-use vials is established to ensure the safety and efficacy of the medication after it has been opened. According to the standards set by the United States Pharmacopeia (USP), multi-use vials, once punctured, typically have a BUD of 28 days. This timeframe is based on stability data, which suggests that most injectable medications can maintain their integrity and dosage potency for that duration under proper storage conditions.

It's essential to adhere to this guideline to minimize the risk of contamination, degradation, and reduced therapeutic effectiveness. Each multi-use vial should also be stored according to specific temperature conditions, and the BUD should be clearly labeled to prevent accidental usage of expired products.

The other options represent durations that do not conform to the established standards for multi-use vials. This reinforces the importance of understanding the specific BUD for various preparation types in sterile compounding to ensure patient safety.
