Bepotastine and Breastfeeding

Summary of use during lactation

There are no reports of infants breastfed during maternal therapy with bepotastine. Because absorption from the eye is limited, bepotastine would not be expected to cause any adverse effects in breastfed infants. To substantially diminish the amount of drug that reaches the breastmilk after using eye drops, place pressure over the tear duct by the corner of the eye for 1 minute or more, then remove the excess solution with an absorbent tissue.

Effects in breastfed infants

Relevant published information on bepotastine was not found as of the revision date. In one telephone follow-up study, mothers reported irritability and colicky symptoms in 10% of infants exposed to various antihistamines and drowsiness was reported in 1.6% of infants. None of the reactions required medical attention and none of the patients were using bepotastine.[1]

Effects on lactation and breastmilk

Antihistamines in relatively high doses given by injection can decrease basal serum prolactin in nonlactating women and in early postpartum women.[2,3] However, suckling-induced prolactin secretion is not affected by antihistamine pretreatment of postpartum mothers.[2] The prolactin level in a mother with established lactation may not affect her ability to breastfeed. Low ophthalmic doses of bepotastine are unlikely to have the same effect on serum prolactin.
