Well, perhaps the most important 'reason' my GI agreed to trial me on it way back when was that I was in terrible trouble... my disease was raging AND expanding at an alarming rate... and nothing in the traditional meds had worked (excepting steroids, and since docs won't/can't keep you on them, it didn't offer a viable long term alternative). Having run out of options (well, almost... but the options left were very scary) she was agreeable to at least looking at LDN (remember, this was back in 07), and having looked at it, thought that at worst it would do no harm; and at best it might offer a solution. However, she did insist on keeping me on 5ASA... (Asacol, Pentasa, Salofalk, etc..) as it at least was considered a traditional med... tho I've never witnessed any benefit from it and I'd been taking it for years. To me, the 5ASA approach is like going fishing with a shotgun. No matter how many shots you take at the water, doesn't mean you actually are going to hit a fish. I'm not so sure 5ASA does no harm. I think it does no good, and may pose a risk. Seems to be a lot of info being generated that it really doesn't belong in the treatment of IBD, but continues because of it being grandfathered into treatment.
