Sheila:  Allegra (fexfenadine) has recently been introduced and is touted
as a "new improved" seldane (terfenadine).  If I recall the drug  company
literature, it is a metabolite of terfenadine which apparently does not
have some of the worrisome interactions with other medications that
terfenadine has had.  Since it is so new, I really can't comment on its
safety in bf, but my usual question is: why does she need to take it?
What else has she tried?  Has she used the extremely effective and much
safer steroid or cromolyn nasal sprays?  What about some other
antihistamines with better track records?  Although the non-sedating
antihistamines such as terfenadine, astemizole (hismanal), and claritin
(can't for the life of me remember the generic name) are extremely
popular because of their non-sedating properties, they are not
necessarily the most effective.  Just some thoughts.  Alicia.
