As I was going over my meds with the IVF nurse today, she gave me a lecture about taking Benadryl and told me not to take it once I get pregnant. She said to only take Claritin or Zyrtec. I said I take it because of my many food allergies, and no matter how hard I try it's impossible to avoid cross-contamination (I've learned that I have major reactions if an ingredient in my food has even touched an allergen in the past). I seriously could not live without Benadryl...I've been on it pretty much forever!

Does anyone have any idea why she might have said this?
