Prepare a prefilled syringe or autoinjector only when you are ready to give it. Call your pharmacist if the medicine looks cloudy, has changed colors or has particles in it. Do not inject into the same place two times in a row. Avoid injecting into skin that is hard, red, bruised, swollen, or tender.

Each prefilled syringe or autoinjector is for one use only. Throw away after one use, even if there is still medicine left inside. Place them in a puncture-proof "sharps" container and dispose of it following state or local laws. Keep out of the reach of children and pets.
