Meclizine Breastfeeding Warnings

Caution is recommended.

Excreted into human milk: Unknown
Excreted into animal milk: Data not available

Comments: Large doses or more prolonged use may cause effects in the nursing infant or decrease the milk supply, particularly in combination with a sympathomimetic such as pseudoephedrine or before lactation is well established.

Antihistamines in relatively high doses given by injection can decrease basal serum prolactin in non-lactating women and in early postpartum women. However, suckling-induced prolactin secretion is not affected by antihistamine pretreatment in postpartum mothers.
