Is Loratadine compatible with breastfeeding? Do we have alternatives for Loratadine?


February 27, 2018 (Very Low Risk)

Second generation anti-histaminic drug with low sedative effect.

Excreted in non-significant amount into breast milk (Hilbert 1988). No side effects were observed in breastfed infants of treated mothers (Merlob 2002).

Various medical societies and expert consensus consider the use of this medication safe during breastfeeding (Butler 2014, Amir 2011, So 2010, Leachman 2006, National Asthma Ed. 2004, Solhaug 2004, Mitchell 1999, Ghaeli 1993).

The British Society of Immunology and Allergy rates it compatible with breastfeeding (Powell 2007).

American Academy of Pediatrics: medication usually compatible with breastfeeding (AAP 2001).


We do not have alternatives for Loratadine since it is relatively safe.
