I take allegra (fexofenadine) for my allergies now im pregnant can i still take them?

No: Allegra is a class c drug which means that it might cause harm to the baby. Class b drugs are a better choice as they are thought not to harm the pregnancy. Class b allergy medications include zyrtek, Claritin and Benadryl (diphenhydramine) (benadryl (diphenhydramine) makes most people sleepy). Nasal steroid sprays like Nasonex are usually considered safe. Call otis at 866-626-6847 for questions about drug safety in pregnancy.
