It's not okay pretty much the only think u can take is tylenol . There's others that you can take tho for allergy . The reason I know is because my doc gave me a list . For allergies take either claritin or benadryl thosecare safe for you and your baby. I hope this helps :) if u need any more help on Meds that are safe to take just ask . By the way congrats on your pregnancy.
I would call your doctor. I know plain Zyrtec is fine to take, but I'm not clear on Zyrtec-D. I believe the only difference is that it has Pseudoephedrine in it, but I'm not 100% and your doctor would be the safest to ask. You should just be able to call and ask and find out over the phone.
i would call your doctor office and just ask the nurse on duty. I know i do that when i have questions and they are always willing to help. good luck!
Talk to your doctor there ARE allergy meds that are safe to take during pregnancy. I have horrible allergies that act up even more when I'm pregnant and I always have to take SOMETHING for them.
