Sorry to hear about the reaction. Lialda and Rowasa both have about the same 10-20% systematic absorption, no difference among them for it. I would not expect Rowasa to be any different or better in that regard.
I would switch to a not 5-ASA/Mesalamine option, like a thiopurine(Imuran/azathiopurine/6-mercaptopurine), or a biologic like remicade/humira.
