Is Xyzal safe to take while pregnant?

Question

Does anyone know if we can continue taking Xyzal (allergy medication)

Answer

Xyzal is in the drug category B, according to the FDA. Doses in excess of 320 times that prescribed to humans showed no negative effects, pregnancy complications or fetal complications. Human studies on the effect of Xyzal during pregnancy have not been completed however, there are no reports of negative side effects in pregnant women or fetuses, thus the pregnancy drug category B. As is the case with all prescription and over-the-counter medication, Xyzal should only be used during pregnancy when absolutely necessary. 
Discuss any concerns about taking the drug during pregnancy with your doctor.

Answer

My Drs office gave me a list at my first appointment.  Only allergy meds that is says are safe to take are Claritin and Zyrtec.  Sudafed and Tylenol sinus.  And saline nasal spray.
