Yes: Zyrtec (cetirizine) is class b. It means that it has been proven through research that is does not cause any fetal harm.

Cat B: Zyrtec (cetirizine) is a category b medicine for pregnancy. Which means that, in animal studies, there is no evidence or very little evidence of problems with use in pregnancy.
