Poorly safe. Evaluate carefully.
Use safer alternative or interrupt breastfeeding 3 to 7 T ½ (elimination half-lives).

Butalbital is a barbiturate with general properties similar to those of amobarbital. It is a sedative-hypnotic drug.
It is used to treat pain in combination preparations with paracetamol or caffeine.
Disused medicine due to risk of overdose and abuse (Suddock 2020).
Since the last update we have not found any published data on its excretion in breast milk.
Its pharmacokinetic data (low molecular weight, low protein binding and very long half-life) makes transfer to milk possible in amounts that could be significant.
A 7-day-old newborn, whose mother was taking a butalbital compound (50 mg) -paracetamol-caffeine four times a day, developed sedation, lethargy, hypotonia, insufficient nutrition, and vomiting. The infant had urine butalbital levels (Vohra 2019).
Safer known alternatives are preferable, especially during the neonatal period and in cases of prematurity (Burch 2020 y 2019, Worthington 2013).
Suggestions made at e-lactancia are done by APILAM´s pediatricians and pharmacists, and are based on updated scientific publications.
