Montelukast (Singulair)

Montelukast (Singulair) is considered compatible with breastfeeding. It's highly protein-bound (99%), which limits transfer into breast milk. While published data on breastfeeding is limited, the pharmacological properties suggest very low infant exposure. It's been used by many breastfeeding mothers for asthma and allergy management without reported adverse effects.

Always confirm with your doctor or lactation consultant before making dietary changes while breastfeeding.
