Pregnancy-Lactation
Pregnancy
Available data from published prospective and retrospective cohort studies over decades in pregnant women have not established a drug-associated risk of major birth defects
Animal data
In animal reproduction studies, no adverse developmental effects were observed with oral administration to pregnant rats and rabbits during organogenesis at doses approximately 100 and 110 times, respectively, the maximum recommended human daily oral dose (MRHDOD) based on AUCs
Poorly or moderately controlled asthma in pregnancy increases maternal risk of perinatal adverse outcomes such as preeclampsia and infant prematurity, low birth weight, and small for gestational age
Lactation
A published clinical lactation study reports presence of montelukast in human milk; data available on effects of drug on infants, either directly or through breast milk, do not suggest a significant risk of adverse events from exposure; effects of drug on milk production are unknown; developmental and health benefits of breastfeeding should be considered along with mother’s clinical need for therapy and any potential adverse effects on breastfed infant from treatment or from underlying maternal condition
