Tezepelumab Injection

WHY is this medicine prescribed?

Tezepelumab injection is used along with other medications to prevent wheezing, difficulty breathing, chest tightness, and coughing caused by asthma in adults and children 12 years and older whose asthma is not controlled with their current asthma medication. Tezepelumab injection is in a class of medications called monoclonal antibodies. It works by reducing a certain type of white blood cell to help decrease swelling and irritation of the airways to allow for easier breathing.

HOW should this medicine be used?

Tezepelumab injection comes as a solution (liquid) in single-dose, prefilled syringes, prefilled dosing pens, and vials to inject subcutaneously (just under the skin) into your upper arm, thigh, or abdomen. It is usually given once every 4 weeks. Your doctor will determine the length of your treatment based on your condition and how well you respond to the medication.

Tezepelumab may be given to you by a nurse or other healthcare provider, or you may be told to inject the medication by yourself at home using a prefilled dosing pen. If you will be injecting tezepelumab yourself, a healthcare provider will show you how to inject the medication. Carefully read the manufacturer's instructions for use that comes with the medication. These instructions describe how to inject a dose of tezepelumab injection using a dosing pen. Be sure to ask your pharmacist or doctor if you have any questions about how to inject this medication. Dispose of used dosing pens in a puncture-resistant container. Talk to your doctor or pharmacist about how to dispose of the puncture-resistant container.

Do not decrease your dose of any other asthma medication or stop taking any other medication that has been prescribed by your doctor unless your doctor tells you to do so. Your doctor may want to decrease the doses of your other medications gradually.

Tezepelumab injection is not used to treat a sudden attack of asthma symptoms. Your doctor will prescribe a short-acting inhaler to use during attacks. Talk to your doctor about how to treat symptoms of a sudden asthma attack. If your asthma symptoms get worse or if you have asthma attacks more often, be sure to talk to your doctor.

What should I know about STORAGE and DISPOSAL of this medication?

Keep this medication in the container it came in, away from light, closed, and out of reach of children. Store tezepelumab injection in the refrigerator. Do not freeze or shake tezepelumab, and do not expose the medication to high temperatures. If a refrigerator is not available, you can store tezepelumab injection at room temperature, away from heat and light, for up to 30 days. Tezepelumab injection should not be put back into the refrigerator after it has been stored at room temperature.

It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location — one that is up and away and out of their sight and reach. https://www.upandaway.org
