@thankful, I'm not sure why some doctors think it's necessary to change treatment plans/medications that work unless there is a really good reason to do so (like new evidence of risks related to a specific drug, etc.). As long as the Remicade is working fairly well, and your wife is happy with the results, it seems like a reasonable idea to stay the course. As informed patient/couple, you can stay abreast of the medical information on long-term use of Remicade and other drugs/treatments. Some people stop responding to a biologic like Remicade after a period of time and *then* switch to another (like Humira, for example); while, everything I've read suggests that it's not generally recommended to start/stop a biologic drug without good reason, as that may impact drug efficacy in the future. Hoping your wife continues to respond well to treatments.
