What is the shelf life of multi-dose vials?

The shelf life of multi-dose vials is generally considered to be 28 days once they are opened. This time frame is established based on the potential for bacterial contamination once a multi-dose vial has been accessed. Each time a vial is punctured, the risk of introducing bacteria increases, which can compromise the integrity of the medication.

To ensure patient safety and medication effectiveness, public health guidelines and regulatory agencies recommend that opened multi-dose vials be discarded after 28 days. This practice helps to minimize the risk of infection and maintain the quality of the medication for its intended therapeutic use. It is important for healthcare professionals to adhere to these guidelines in order to ensure patient safety and proper medication management.
