We are allowed to take Benadryl! check with your Dr first but mine said it was safe :)
If you have an allergist call and all them. I believe you can take ceterizine it is the generic of zyrtec i believe and it's class b. Or over the counter chlortrymeton(spelling) id what my OB suggested for my allergies when they were driving me nuts.
clariton is fine too... thats what my midwife told me to take.
I take Zyrtec for my allergies and Singulair as needed. But Singulair is a script. Clariton doesnt help me lol
Benadryl is fine. But check with your physician
