What is Haegarda?

Haegarda is a man-made form of a protein in blood that helps control swelling in the body. People with a condition called Hereditary Angioedema (HAE) do not have enough of this protein. Hereditary Angioedema can cause attacks of swelling and symptoms such as stomach problems or trouble breathing.

Haegarda is an injectable medicine used to prevent swelling and/or painful attacks in patients 6 years of age and older with Hereditary Angioedema.

Haegarda should not be used to treat an acute HAE attack. In case of an acute HAE attack, initiate individualized treatment as discussed with your health care professional.

Warnings

You should not use Haegarda if you have experienced life-threatening immediate hypersensitivity reactions (allergic reactions), including anaphylaxis, to the product.

Before taking this medicine

You should not use Haegarda if have ever had a life-threatening allergic reaction to c1 esterase inhibitor.

To make sure Haegarda is safe for you, tell your doctor if you have:

  • a stroke or blood clot;

  • heart problems; or

  • an "in-dwelling" catheter.

Tell your doctor if you are pregnant or breast-feeding.

Haegarda is made from donated human plasma and may contain viruses or other infectious agents. Donated plasma is tested and treated to reduce the risk of contamination, but there is still a small possibility it could transmit disease. Ask your doctor about any possible risk.

How should I take 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.
