Ha! I found it!! I didn't think I'd be able to but I still have the can of it. The brand name is Questran Poweder and the generic is cholestyramine. Here is some general info about it but you can research a lot more online if you want. It worked for me. Hope this helps. I had the orange flavor and it was like tang.
What is Questran?
Questran (cholestyramine) is a drug which absorbs bile acids in the intestines. There are two forms of Questran: the standard form, which contains cholestyramine and sucrose, and Questran Light, which contains cholestyramine and aspartame (aspartame is an artificial sweetener). It's worth nothing that artificial sweeteners can cause gastrointestinal symptoms in some people, including diarrhea, and some IBS sufferers may be sensitive to the aspartame in Questran Light.
What symptoms does it treat?
Questran is used to treat diarrhea, as excess bile acid in the intestines can lead to loose stools. In particular, patients who have had their gallbladders removed may find that they have bile-related diarrhea, as bile is normally stored in the gallbladder.
How is it taken?
Questran comes in powder form and is mixed with water or another liquid before swallowing. It is very important to follow all directions from your doctor when taking Questran, as it can prevent the absorption of vitamins if taken long-term, which could have serious health effects if not taken into consideration.
