Very Low Risk for breastfeeding

Safe. Compatible.
Minimal risk for breastfeeding and infant.

A second generation antihistamine that does not cross the blood-brain barrier, with no sedative or antimuscarinic effects (AEMPS 2015).
Oral administration or as eye drops.

Since the last update we have not found published data on its excretion in breastmilk.

Second generation antihistamines are considered safe during breastfeeding due to their lack of sedative effect as they do not cross the blood-brain barrier. When taken orally, it is recommended to use the lowest effective dose.

Until there is more information about this drug taken orally in relation to breastfeeding, safer known alternatives may be preferable, especially during the first month and in mothers of premature infants.

The small dose and poor plasma absorption of most topical ophthalmic preparations make it unlikely that significant amounts will transfer into breastmilk.
Ophthalmic epinastine reaches insignificant plasma concentration: 0.042 ng/ml (Allergan 2018 and 2012).
In ophthalmic administration, absorption can be minimized by pressing the tear duct (inner canthus of the eye) for 1 minute with a finger.

Its ophthalmic use is compatible with breastfeeding.
