Singulair and pregnancy: what we know
Pregnancy and breastfeeding are special periods where every medication choice deserves careful review. Singulair (Montelukast) is no exception. The prescribing information for Montelukast provides specific guidance, and the right decision depends on the indication, alternatives, gestational stage and the woman's overall medical picture.
Pregnancy safety data for Singulair
According to the prescribing information for Montelukast, the available human data in pregnancy may be limited, supportive, or restrictive depending on the molecule. Some Respiratory Medications agents are routinely used in pregnancy when needed; others are avoided. The risk-benefit calculation includes the importance of treating the underlying condition and the consequences of leaving it untreated.
Breastfeeding considerations
Breastfeeding considerations are usually separate from pregnancy considerations. Some active ingredients pass into breast milk in negligible amounts; others are present at levels that warrant caution. Montelukast selectively blocks the CysLT1 receptor, which mediates the action of leukotrienes C4, D4 and E4 — proinflammatory mediators released by mast cells and eosinophils. The prescriber weighs the benefit of breastfeeding, the importance of Singulair, and the availability of alternative therapies.

Effects on the fetus or breastfed infant depend on whether the active ingredient Montelukast crosses the placenta or enters breast milk and at what concentrations.
