I'm 10w pregnant & i've allergy that keeps getting worse sneezing itching ears & throat congestion & the pa told me i can take allegra (fexofenadine) ! is it safe?

No Allegra (fexofenadine): Claritin (loratadine) and Zyrtec (cetirizine) are pregnancy category B medications which means that animal reproduction studies have failed to demonstrate a risk to the fetus. I frequently use these medications with my pregnant patients. Allegra (fexofenadine) is category C so I would avoid this medication and stick with the ones listed above. If concerned, talk to OB/GYN about specific medications.
