OK, I can understand why your GI thinks it won't hurt. It is considered safer than taking an aspirin. My own GI gave it to me... confidentially.. back in 2006 because she was sure it wouldn't hurt. And there was a chance... based on only one study back then, it might help. And help it did... for 6 1/2 years... at virtually no risk to me. As to why a doctor, a GI, might say he/she didn't think it would help, multiple studies show it should help 3/4+ on average of the people who take it as prescribed. Highest/most optimistic.. is near 90%
Now, perhaps your GI has info that tells him/her that, in conjunction with Remicade, LDN does not have an immune system capable of fighting off any disease. However, others on here say that LDN doesn't use the immune system to work. I'm not sure which is the case. I guess, if it can do no harm... then the question is... will it do any good. Only way to find out is to try it... while the LDN is fresh. Once it goes stale, it can't be relied on, OK
