I'm not sure about the remicade, but the B12 should always be continued. And one can develop much more than anemia. Neurological problems can develop such as neuropathy, memory problems and attention difficulties. Most cronnies don't absorb B12 very well because the terminal ileum is usually involved and develop scarring. Some B12 experts agree that SL methylcobalamin is as effective as injections. I get mine at Whole Foods or my local vitamin shop. My life changed 3 yrs ago due to B12 deficiency (I have had 3 resections) and most symptoms are improved but are still present.
