In brief: Maybe
Zafirlukast, marketed as Accolate (zafirlukast) for asthma, does not currently have published studies on safety in pregnancy or breastfeeding, but information suggests the amount found in breast milk is low.
It's best to discuss this drug & your specific situation with your personal pediatrician or ob/gyn. Check out lactmed for info on drugs & breastfeeding: http://toxnet.Nlm.Nih.Gov/cgi-bin/sis/htmlgen?Lact.

In brief: Pregnancy categories
Zafirlukast has been assigned to pregnancy category b by the fda.
Zafirlukast is excreted into human milk. The manufacturer recommends that due to the potential for serious reactions in nursing infants, a decision should be made to discontinue nursing or discontinue the drug, taking into account the importance of the drug to the mother.
