We do not believe that the ingredients in Allermi at the dosages prescribed are unsafe to use in pregnancy or while breastfeeding, and very little medication, if any, is systemically absorbed.
However, because these ingredients have not been well-studied in or FDA-approved for the pregnant or breastfeeding population, we err on the side of caution and are not treating pregnant or breastfeeding moms at this time.
We recommend consulting your OBGYN or pediatrician for their recommendations on treating rhinitis during pregnancy or breastfeeding, and what medications they're comfortable with you using.
