Cimzia was a great drug for me. I was always classified as moderate to severe, although more on the severe side, because of major bleeding issues and Cimzia helped keep me in remission for several years. I never experienced nausea or any major side effects from it although it took about
3-4 weeks for it to kick in but when it did, it was a miracle drug for me.
I hope the nausea passes. Maybe try switching to clear liquids for a day and then slowly introduce foods that are very easy on the stomach.
I hope you are feeling better soon and that the Cimzia brings you a nice long remission!
