苯海拉明

It is a first generation antihistamine drug (Ethanolamine) with a strong sedative effect.  Used in allergic conditions and in motion sickness. Oral administration 3 to 4 times a day

Its large volume of distribution possibly explains the negligible passage into breast milk observed. ^{(Rindi 1951)}

No problems have been observed in infants whose mothers took it for a long time ^{(Kaya 2014)}, except for an isolated case of sedation. ^{(Ito 1993)}

The absorption from ingested mother's milk to the infant's plasma is hampered by a low oral bioavailability.

Neither a decrease of milk production nor alteration of Prolactin release have been shown with the use of this drug. ^{(Butler 2014)}

For both, the mother and the infant is safer the use of antihistamine medication with higher safety levels without sedative effect ^{(Butler 2014)}, especially when the child is a premature or younger than 1 month old.

Expert authors consider the use of this medication possibly safe during lactation. ^{(Hale, LactMed, Briggs 2015, Schaefer 2015, Rowe 2013, Nice 2000)}

When used while breastfeeding do it with the lower dose as possible and avoid a long-term use.

Check up for feeding difficulty and somnolence in the infant. Bed-sharing with the infant is not recommended for parents who are on this medication. ^{(UNICEF 2018, 2017, 2014, 2013 y 2006, Landa 2012, ABM 2008)}
