Tezspire contains the active substance tezepelumab, which is a monoclonal antibody. Antibodies are proteins that recognise and bind to a specific target substance in the body, which in the case of tezepelumab is a protein called thymic stromal lymphopoietin (TSLP). TSLP plays a key role in causing the inflammation in your airways that leads to the signs and symptoms of asthma. By blocking the action of TSLP, this medicine helps to reduce inflammation and asthma symptoms.

Tezspire is used with other asthma medicines to treat severe asthma in adults and adolescents (12 years of age and older) when the disease is not controlled with their current asthma medicines.

Tezspire may reduce the number of asthma attacks you experience, improve your breathing and reduce your asthma symptoms.

• if you are allergic to tezepelumab or any of the other ingredients of this medicine (listed in section 6). If this applies to you, or if you are not sure, check with your doctor, pharmacist or nurse.

Talk to your doctor, pharmacist or nurse before using Tezspire.

• Tezspire is not a rescue medicine. Do not use it to treat a sudden asthma attack.
• If your asthma is not getting any better, or it gets worse during treatment with this medicine, talk to a doctor or nurse.
• Look out for signs of allergic reactions. Medicines like Tezspire can potentially cause serious allergic reactions in some people. The signs of these reactions may vary, but can include swelling of your face, tongue or mouth, breathing problems, fast heartbeat, fainting, dizziness, feeling lightheaded, hives and rash. If you notice any of these signs, speak to a doctor or nurse immediately.

Talk to your doctor about how to recognise early signs of allergy, and how to manage reactions if they occur.

• Look out for any signs of a possible serious infection while you are taking Tezspire such as:
  • fever, flu-like symptoms, night sweats;
  • cough which will not go away;
  • warm, red and painful skin, or a painful skin rash with blisters.

If you notice any of these signs, speak to a doctor or nurse immediately.

If you already have a serious infection, talk to your doctor before taking Tezspire.

• Look out for any symptoms of a heart problem, such as:
  • chest pain;
  • shortness of breath;
  • a general feeling of discomfort, illness, or lack of well-being;
  • feeling lightheaded or faint.

If you notice any of these symptoms, speak to a doctor or nurse immediately.

• If you have a parasitic infection or if you live in (or travel to) an area where parasitic infections are common, talk to your doctor. Tezspire may weaken your body’s ability to fight certain types of parasitic infections.

Do not give this medicine to children under 12 years of age because the safety and benefits of this medicine are not known in children in this age group.

• Do not suddenly stop taking your other asthma medicines when you start Tezspire. This is especially important if you take steroids (also called corticosteroids). These medicines must be stopped gradually, under the supervision of your doctor and based on your response to Tezspire.

• if you are taking, have recently taken or might use any other medicines.
• if you have recently had or are due to have a vaccination.

• If you are not sure when to inject Tezspire, ask your doctor, pharmacist or nurse.

• Do not stop using Tezspire without speaking first to your doctor, pharmacist or nurse.
