Quick summary

Tezspire (tezepelumab) is a treatment used for certain people with severe asthma and chronic rhinosinusitis with nasal polyps. It is given as a subcutaneous injection and is not a rescue medicine for sudden asthma symptoms.

Medical disclaimer

This article is a general summary of the patient leaflet and does not replace the official leaflet or advice from a doctor, nurse, or pharmacist. Always follow the instructions given with your prescribed medicine.

What is Tezspire and what is it used for?

Tezspire contains tezepelumab. It is described in the leaflet as a medicine used to help manage severe asthma and chronic rhinosinusitis with nasal polyps in patients over 12 years old.

It is used as an additional treatment alongside other therapies. It is not intended to treat a sudden asthma attack.

How Tezspire works

Tezspire works by targeting the TSLP protein, which is involved in inflammation in the airways. By blocking this protein, it helps reduce inflammation and support better breathing control.

This mechanism is one reason it may be used in people whose symptoms have not been adequately controlled with existing treatment.

How Tezspire is given

Tezspire is given as a subcutaneous injection, meaning it is injected under the skin.

The leaflet states the usual dose as 210 mg every four weeks. A healthcare professional may show the patient or caregiver how the injection is given.

Rotating injection sites may help reduce local discomfort. If there is any uncertainty about the injection process, the official leaflet and healthcare team should be consulted.

As with any medicine, Tezspire may cause side effects, although not everyone gets them. The current content mentions the following possible effects:

  • Pain or discomfort at the injection site
  • Respiratory infections
  • Headache
  • Fatigue
  • Flu-like symptoms

Allergic reactions are also important to watch for. The leaflet summary mentions rash, itching, or swelling as possible warning signs that should be discussed with a healthcare professional.

Precautions and important safety points

Before using Tezspire, the patient should discuss their medical history with a healthcare professional. The current content highlights the following points to check:

  • Any previous allergic reaction to tezepelumab or similar medicines
  • Other medicines being used, including corticosteroids
  • Whether live vaccines are planned or being given

The content also notes that corticosteroids should not be reduced suddenly without medical guidance.

Who may not be suitable for Tezspire?

Tezspire is not suitable for everyone. The content states that it should not be used in people with a known hypersensitivity to tezepelumab or any of its components.

Questions about suitability should be reviewed with a doctor or pharmacist using the official leaflet and the patient’s own medical history.

What to discuss with a doctor or pharmacist

Before treatment, it is sensible to confirm:

  • Why Tezspire has been prescribed
  • How and when the injection should be given
  • What to do if a dose is missed
  • Which side effects should be reported promptly
  • Whether any vaccines or other medicines need review

This helps the patient use the medicine in line with the prescribed plan and the official leaflet.
