How long may an opened vial of Heparin be kept?

An opened vial of Heparin can be kept for up to 28 days. This time frame is based on stability studies and the manufacturer's guidelines, which indicate that after being opened and used, the efficacy and safety of the medication can be assured for this duration. Beyond 28 days, the risk of decreased effectiveness or increased potential for contamination rises, thus it is essential for healthcare providers to adhere to this guideline to ensure patient safety. Therefore, understanding the proper storage and handling of medications like Heparin is crucial in a clinical setting to maintain high standards of care.
