Sunnybear,
Yucch, 6 a day!

...especially hard with a drug that causes indigestion.)
Anyway, it's a type of medication that is pretty innocuous in that it really never leaves the digestive canal. It's a bile-sequesterant (attaches to bile) in the intestines and it prevents the bile (which is VERY high in cholesterol) from being reabsorbed. THis bile shortage keeps the liver making more and consequently results in cholesterol being removed from the bloodstream.
Unfortunately it's effects when taken alone are not stellar: (TC down 7, LDL down 15, HDL up 3, TRIG up 10)
It's often given with statins to boost the total effect, especially the LDL effect.
Just checked the price...at a buck a tablet this is a pretty pricey drug for the small bang it delivers.
Did your doctor give you this because you wanted (or had to have) the non-statin route?
