<p><strong>Pregnancy</strong>: The safety of Zafirlukast in human pregnancy has not been established. In animal studies, Zafirlukast did not have any apparent effect on fertility and did not appear to have any teratogenic or selective toxic effect on the foetus. The potential risks should be weighed against the benefits of continuing therapy during pregnancy and Zafirlukast should be used during pregnancy only if clearly needed.<br />
<br />
<strong>Lactation</strong>: Zafirlukast is excreted in human breast milk. Zafirlukast should not be administered to nursing mothers.</p>
