Has anyone tried this drug for Crohn's? (It's sold in Canada, mostly as an anti-histimine/allergy and asthma drug, maybe in Europe as well, but can be purchased from compounding pharmacies in the US). It has relatively few side effects, and studies indicate that it may be able to heal the intestinal lining after long-term use. (At least, that's what I have gathered so far, from the few clinical studies/published articles on it I found using Canadian Google). Also, my pharmacist raves about it; he has been taking it himself for about a year. While he strongly advocates Ketotifen for treating intestinal disorders and allergies, I'm wondering if anyone else has had any success (or lack-there-of) with this drug?
