The appropriate handling of vasopressin tannate in oil is crucial for its effectiveness. Storing the medication in a refrigerator and allowing it to stand at room temperature for 30 minutes before administration is not correct for this specific medication. Instead, holding the vial under warm water for 10–15 minutes and shaking it vigorously ensures proper mixing and activation of the medication in the oil solution. Weighing once a week and limiting fluid intake are not directly related to the proper administration of this medication.
