Mixing and storage

Add 1 mL bacteriostatic water or the supplied saline to the 75 IU vial, swirl gently, and draw the whole vial, which is 75 IU, 100 units on an insulin syringe. For 150 IU, mix two vials in the same 1 mL. Before mixing, keep vials between 3 and 25 degrees C away from light. After mixing, inject right away; it does not keep well once dissolved.
