<p><strong>Pregnancy</strong>: There are no studies of Zaleplon in pregnant women; therefore, it is not recommended for use in women during pregnancy. Zaleplon has no established use in labour and delivery.<br />
<br />
<strong>Lactation</strong>: A study in lactating mothers indicated that the clearance and half-life of Zaleplon is similar to that in young normal subjects. A small amount of Zaleplon is excreted in breast milk, with the highest excreted amount occurring during a feeding at approximately 1 hour after Zaleplon administration. Since the small amount of the drug from breast milk may result in potentially important concentrations in infants, and because the effects of Zaleplon on a nursing infant are not known, it is not recommended in nursing mothers.</p>
