Zyrtec for allergies

Anyone else taking Zyrtec for seasonal allergies? Mine have been TERRIBLE. I finally caved yesterday and used it, its on the “safe” list from my OB. Just want to see if others are taking it at the advice of their doctor too. I’m having a c section next week and am going to call tomorrow to make sure its fine to take up until then if necessary and perhaps after. Allergies have been making me cough and I would really love to avoid that after my c section. So far it’s worked magic, I feel sooooo much better.
