Ask your doctor. Don't self-prescribe something as far-reaching as an allergy med.
My doctor actually told me that allegra was fine to take as long as its the regular kind not allerga D. But I didn't take it all of the time... N my baby is perfectly healthy, benadryl is good to take too.U should ask ur doctor n see what ur comfortable taking Bcus everyone is different. Good luck:-)
I also took allegra before pregnancy, it was the only thing that worked. However, it is not advised during pregnancy. Take Benadryl instead. Its a safe drug to take while carrying baby.
