@altabiznet Yes, I was referring to rituximab. I went to the ER because i was not told to stay away from tomatoes and sauces made with them. My husband had made a good dinner featuring lasagna! I commented during dinner that I had to go to the bathroom. I got as far as the bedroom when I felt like I was being viciously stabbed! Hubbie was able to quiet me down after a time and said we needed to go to ER. The doc thought that I had ruptured an ulcer in my duodenum. Talk about a scary time. I went straight home, too some pain meds from the ER, and went to bed! I was fine with the other doses. The chemo drug was cytoxan and now you know to stay away from tomato products! The 8 cycles worked. They set my immune system back a little and then i was able to start CellCept!
