Have you taken any medications other than the Asacol? Methotrexate is available in pill form, so that is an option. Imuran / Azathioprine / 6-MP are also pills. Has your doctor suggested any of these medications?
I am taking Imuran too. But my doctor knows of my very bad phobia and said for me to take Humira, I will talk about taking other pills with him and about Methotrexate.
