I have had great luck with LDN (Low dose Naltrexone). If you have already started on Remicade, then stick with it. My understanding is that if for any reason, one starts on Remicade... but discontinues it.. the chances of successfully going back on it are slim.
As for LDN, the problem with it is finding a doctor who will prescribe it. It has NOT been FDA approved for treating IBD. Many are hoping that approval will come sometime next year. Despite that, it is legal and ethical for doctors to prescribe it.. the practice of doing so is referred to as 'off label' or 'off patent' prescribing. However, most doctors are reluctant to take this course. As for the treatment itself, it is perhaps the safest option out there. In a Norwegian documentary posted elsewhere on this forum, a doctor in Dublin, Ireland, who has been prescribing it for quite some time described it as being safer than taking an aspirin. In Norway, it has been used for many diseases for over a decade. I've been on it since November of 2007, so this year will mark my 6th anniversary.. and the only side effect I personally ever experienced was vivid dreams. It can cause some to have sleep disruptions, or experience a feeling of being 'wired'. If you can get a prescription... then you need to find a competent pharmacy to compound it... when I started on it, there were only 6 in North America, and only 1 in Canada. Now there are 3 right here in Halifax. But the knowledge, awareness and use of LDN has been slow to spread. Lack of FDA approval, doctors reluctance, and limited compound pharmacies are the issues. If these do not discourage you, then this is what you might expect. Try LDN on your son. If he is within the majority of people who've tried it, then you should expect to see a slow, almost imperceptable improvement over the span of 12 weeks. LDN does not produce immediate results. It is not a eureka pill. But, when it does kick in, and the healing commences... the results are definite, and improvement seems to continue and continue to a point where it is almost as if the disease had never happened. It can't undo the damage done by the disease, scar tissue is permanent, but otherwise... that little pill can force, and keep, the disease in a state of 'retirement'.
Anyway, this is not a sales pitch. LDN saved my life, and I feel I owe it to others to tell folks about it. It is not snake oil, it is not voodoo, it is medical science with a pedigree of having been used to treat a variety of diseases (auto-immune related) for a decade.
2 adult studies, and 1 pediatric study have shown it is a SAFE, effective treatment for IBD.
