It is a first generation antihistamine drug (Ethanolamine) with a strong sedative effect. Dimenhydrinate is a combination of diphenhydramine and 8-chlorotheophylline in salt form, with 55% diphenhydramine and 45% inactive 8-chlorotheophylline. Its active drug is diphenhydramine. Used 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, Briggs 2015, Rowe 2013, Worthington 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. (ABM 2020 & 2008, UNICEF 2018, 2017, 2014, 2013 y 2006, Landa 2012)
