Each single-use vial (bottle) of this medicine is for one use only. Throw away after one use, even if there is still some medicine left in it after injecting your dose.

Store the unmixed powder medicine in the refrigerator and protected from light. Do not freeze. Keep each vial in the original container until you are ready to mix your medicine.
