Very Low Risk

Safe. Compatible. Minimal risk for breastfeeding and infant.

Short-acting benzodiazepine. Indications: anxiety, insomnia.
Oral administration 1 to 3 times a day.

It is excreted in breast milk in insignificant amounts (Nishimura 2021, Lemmer 2007, Summerfield 1985, Whitelaw 1981) and no problems have been observed in infants of mothers taking it at the normal dose (Nishimura 2021, Kelly 2012, Johnstone 1982, Whitelaw 1981).

Expert authors consider the use of lorazepam to be safe or very probably safe during breastfeeding (Hale, Lactmed, Uguz 2021, Briggs 2015, Schaefer 2015, Nice 2004).

The occasional and low-dose use of benzodiazepines is compatible with breastfeeding (Kelly 2012, Rubin 2004, Iqbal 2002, Hägg 2000, McElhatton 1994, Lee 1993, Kanto 1982).

Choose short-acting benzodiazepines and use the lowest effective dose (Rowe 2013), especially during the neonatal period and in prematurity, as they can accumulate in the infant during chronic use (Sachs 2013).

It is advisable to monitor drowsiness and adequate feeding of the infant.
Bed-sharing with the baby is not recommended if this medicine is being taken due to increased risk of suffocation or sudden infant death (UNICEF 2018, 2017, 2014 and 2013, Landa 2012, ABM 2008, UNICEF 2006
