Elestat and Breastfeeding
No human studies have been conducted on breastfeeding and Elestat (epinastine ophthalmic solution), so the full risks of using this drug while breastfeeding are not known. Since the medication is an eye drop (and little of it will actually reach the bloodstream), it is unlikely that a significant amount would reach the breast milk. Before using this medication, breastfeeding women should consult their healthcare providers.
