100 mg. sounds high to start with. I'd question it. It takes up to 3 months to get into your system, and I think it is better for maintenance than to manage a flare. You should stay on the Colazal while it builds up. My daughter is still on both, but it helped her to wean from the Pred. Make sure the doc is testing your enzymes on a regular basis. Each body metabolizes the 6mp differently, and there can be wide swings in the number. Test is expensive and takes a week or so to get results, so stay on it. Goal is to stay in the 200-400 range, whatever that means... her dose alternates between 50 and 75 mg on alternate days.
Hair loss is real. Many posters cannot tell from which drug it comes, but our experience points to the 6mp. Not noticeable to most, but the shower drain doesn't lie. Not a big issue for most either, but it may be a sign the levels are too high.
Daughter,15 diagnosed 1-08 w/ UC Learning from you all.
Asacol, Prevacid, Flagyl, Prednizone 50mg, major flare, now off!, Hosp. @ U of C, Comers, four x this yr. Low residue diet still, and still having problems.
6MP, Colazol ,horrible acne/moon for awhile- No more Pred,but 6mp isn't working. Remicade next up.
Trying probiotics, fish oil, and Mangosteen for kicks.
On 2nd infusion of Remicade, and still on all of the other drugs., except Flagyl and Pred. Better, not healed.
