Yes, I Am Supposed To Stop All Antihistimes Before My

Yes, I am supposed to stop all antihistimes before my allergy testing. I take zyrtec every day so I know that is something that I need to stop 3 days before my allergy testing, but I am also wondering how to tell if any of the over the counter meds that I take have antihistimes in them.

never mind, I thought this was a free service, I'll just call my own Doctor's office and ask this question. Bye!
