Dear Lauren, I looked in my book "When Words Are Not Enough" by Valerie Davis Raskin MD, Zoloft is considered a "Class B" drug not a "C" Paxil is a "C" and the benzodiazpines too, which you do not take so you dont have to worry. The book was written a few years ago but this is an excellant book Lauren if you could go to the Libarary or book store it has alot of information about pregnancy and psych drugs, breastfeeding etc.... I checked twice Zoloft is a "B" according to this woman Doctor, also Buspar is a "B" also. Xanax is a "D" Klonopin a "C" and so on.... I do not know too much about sudafed, I will check the web and write you back, it seems Zoloft is pretty safe and is a "B" like Buspar, I do not blame you for being confused, unless they changed the class, Prozac is a "B" too. I will check on Sudafed for you, I am really not sure. Call the OB, some err on the side of caution I know and some are more liberal. Besides this book by Dr. Valerie Davis Raskin, another is "What to expect what you are expecting" its like a bible, its a very upbeat positive book it helped me alot. Please let me know how you are doing, its normal to worry a little in early pregnancy, you are going to be fine! How is the weaning going, today was my "skip a day" I was more hungry but thats it, I had a pretty good day which I am grateful for. God bless, Debbie.
