To our medication experts (some of whom are out of town, I think): Of the common nonsedating antihistamines used around here for seasonal allergies, namely claritin (loratadine), allegra (fexofenadine), and seldane (terfenadine) - which would be best used by the nursing mother as far as its safety for her child. Is there any new info on them? There is very little info available in the usual refs. The loratadine has been tried and did not work well, dr. wants mom to use fexofenadine. The nursling in question is a healthy 3 y.o., nursing a.m., naptime, evenings, and a few times at night. Thanks Laurie Wheeler, Rnc, mn, ibclc Violet LA (s.e. US) - allergy season is upon us.
