About Tezspire
Overview
Tezspire contains tezepelumab-ekko, a monoclonal antibody supplied in a pre-filled pen for injection under the skin. It is an add-on maintenance treatment for adults and children aged 12 years and older with severe asthma or inadequately controlled chronic rhinosinusitis with nasal polyps. It blocks TSLP, a protein involved in inflammation, although exactly how it works in these conditions has not been definitively established. It is not for relief of sudden or severe, prolonged asthma attacks.
What it treats
- Add-on maintenance treatment for severe asthma in adults and children aged 12 years and older. Not for relief of sudden airway tightening or a severe, prolonged asthma attack. - Add-on maintenance treatment for inadequately controlled chronic rhinosinusitis with nasal polyps in adults and children aged 12 years and older.
Safety information
Side effects
Common side effects reported in at least 3% of patients varied by condition: • Asthma: sore throat, joint pain and back pain. • Chronic rhinosinusitis with nasal polyps: cold symptoms, upper respiratory tract infection, nosebleeds, sore throat, back pain, flu, injection-site reactions and joint pain. Allergic reactions can occur, including rash and allergic eye inflammation. Contact a doctor if these develop. Anaphylaxis, a severe allergic reaction requiring immediate medical attention, has been reported after Tezspire use.
When to call your doctor
If symptoms are severe or getting worse quickly, seek emergency care rather than waiting.
Before taking this medicine
Do not use Tezspire if you have a known allergy to tezepelumab-ekko or any of its other ingredients. Allergic reactions, including rash and allergic conjunctivitis (an allergic eye reaction), have occurred after treatment. Anaphylaxis, a severe allergic reaction, has also been reported and requires urgent medical treatment. Do not suddenly stop systemic or inhaled corticosteroids when starting Tezspire. Any reduction should be gradual and guided by your prescriber. Any existing parasitic worm infection must be treated before starting Tezspire. If an infection develops during treatment and does not respond to treatment for the infection, Tezspire should be stopped until the infection clears. Avoid live attenuated vaccines during treatment.
Interactions
No formal drug interaction studies have been performed with Tezspire.
