Zafirlukast, sold under the brand Accolate among others, is a medication used for the long term treatment of asthma and allergic rhinitis. It is less preferred to inhaled steroids for asthma. It is taken by mouth. Benefits may take up to two weeks to occur.

Common side effects include headache and stomach upset. Severe side effects may include liver problems and potentially Churg-Strauss syndrome. Use is likely safe in pregnancy. It is a leukotriene receptor antagonist (LTRA) and works by decreasing airway mucous, swelling, bronchoconstriction, and inflammation.

Zafirlukast was approved for medical use in the United States in 1996. It is approved in some but not all parts of Europe. In the United States it costs about 34 USD per month as of 2021.
