How should I use Haegarda?
Use Haegarda exactly as prescribed by your doctor. Follow all directions on your prescription label and read all medication guides or instruction sheets.
Haegarda is injected under the skin. A healthcare provider will give your first dose and may teach you how to properly use the medication by yourself.
Read and carefully follow any Instructions for Use provided with your medicine. Prepare an injection only when you are ready to give it. Ask your doctor or pharmacist if you don't understand all instructions.
Storing unopened vials: Store in a refrigerator or at cool room temperature and use until expiration date. Protect from light and do not freeze.
Each vial (bottle) is for one use only. Throw it away after one use, even if there is still medicine left inside.
After mixing Haegarda, use the injection right away or store at room temperature and use within 8 hours.
Haegarda contains no preservative. Once you have pierced the rubber top of a vial with a needle, you must use that vial right away or throw it away.
Use a needle and syringe only once and then place them in a puncture-proof "sharps" container. Follow state or local laws about how to dispose of this container. Keep it out of the reach of children and pets.
