Zaleplon Levels and Effects while Breastfeeding

Summary of Use during Lactation

Because of the low levels of zaleplon in breastmilk and its short half-life, amounts ingested by the infant are small and would not be expected to cause any adverse effects in breastfed infants. No special precautions are required.

Drug Levels

Maternal Levels. Five nursing mothers who were at least 14 days postpartum were given a single oral dose of zaleplon 10 mg. The peak milk level averaged 14 mcg/L at 1.2 hours after the dose. The mean half-life in milk was 1.1 hours.[1] Using the peak milk level data from this study, an exclusively breastfed infant would receive an estimated maximum of 2.1 mcg/kg daily with this maternal dosage regimen or about 1.4% of the maternal weight-adjusted dosage.
