How to prepare your insulin dose if you are using two types of insulin: 1  When you mix regular insulin with another type of insulin, always draw the regular insulin into the syringe first. When you mix two types of insulins other than regular insulin, it does not matter in what order you draw them into the syringe.
Insulin detemir (Levemir) and insulin glargine (Lantus) SHOULD NOT be mixed in the same syringe with ANY other drug or insulin. To mix two insulins, such as insulin aspart (Novolog) and insulin isophane (NPH) remember you must draw up the clear insulin first. So first, you roll the bottle of NPH (the CLOUDY insulin) to mix it.
