Is Allerease safe while pregnant?

Ma

Hey all! As allergy season approaches soon I wanted to get everyones opinion on this product. This is what I took normally for my allergies and it worked wonders! I asked my Dr about it and he had no idea whether it was safe or not. He googled it and it said it was in the safe list along with Claritin. Has anyone else been taking this while pregnant or know if its okay to take while pregnant?
