Parenteral Administration of Medications: Mixing Insulins:

Patients whose blood glucose levels are well controlled on a mixed-insulin dose need to maintain their individual routine when preparing and administering their insulin. Do not mix insulin with any other medications or diluents unless approved by the health care provider Never mix insulin glargine (lantus) or insulin detemir (Levemir) with other types of insulin. Inject rapid-acting insulins mixed with NPH (neutral protamine Hagedorn) insulin within 15 minutes before a meal. Verify insulin doses with another nurse while preparing the injection.
