TEZSPIRE works by blocking the action of thymic stromal lymphopoietin (TSLP), a protein that plays a role in causing the signs and symptoms of asthma and CRSwNP.
Asthma
TEZSPIRE may reduce the number of asthma attacks you experience, improve your breathing and reduce your asthma symptoms.
CRSwNP
TEZSPIRE may reduce the size of your polyps and improve symptoms including nasal congestion and loss of smell. TEZSPIRE may also reduce the need for oral corticosteroids and surgery.
The ingredients in TEZSPIRE are:
Medicinal ingredient: tezepelumab
Non-medicinal ingredients: glacial acetic acid, L-proline, polysorbate 80, sodium hydroxide, and water for injection.
