I do not take WelChol, however, I took Questran Light for 10 years and regret it. I think these two drugs are similar.
It did not really lower my lipid values that much, but the Dr. thought I was too young to go on statins (I was 50 at the time) -- so I continued to take it.
I was so chronically constipated it was horrible. I stopped the Questran in 1999, and my bowels still have not returned to normal. The Dr. says I now have a motility problem, perhaps from such chronic constipation for all those years. I have had a colonoscopy and they find nothing wrong, but I now must take Miralax every morning and watch my diet like a hawk to make sure I have enough insoluble fiber to keep me moving.
In my opinion -- if you are going to take one of these types of drugs -- don't take it as long as I did -- and certainly not if your numbers don't drastically improve. The price you pay down the road may not be pleasant.
Just my opinion.
