Zafirlukast indications?

What is zafirlukast used for (its approved indications)?

Zafirlukast is an oral leukotriene receptor antagonist used for:
- Asthma: to help prevent and control chronic asthma symptoms, including maintenance treatment for patients who need long-term control [1].
- Allergic conditions: it is also used for seasonal allergic rhinitis [1].

How is it typically prescribed for asthma?

For asthma, zafirlukast is generally prescribed as a daily controller medication rather than a rescue treatment. It is intended to reduce the frequency and severity of asthma symptoms over time [1].

Is zafirlukast used for acute attacks or bronchospasm?

Zafirlukast is not meant to treat acute asthma attacks. It is used for maintenance/prevention of asthma symptoms, while rescue therapies (like short-acting bronchodilators) are used for sudden symptoms [1].

Where can I check the exact FDA-approved labeling?
