Welchol and meds

I decided to read about side effects of Welchol. I just got back from the doctor's and she gave me some free samples of this. In the past, I had been on Lipitor and Zetia but had terrible back, hip and leg pain. I went off of those and I was fine. Started on Crestor- same pain in back, hips and legs. Now my doctor says that Welchol is not absorbed in the blood stream so there should be no side effects- only possible heartburn. After reading all of these side effects that everyone is having on Welchol, I am not going to even try it.
I am going to record everything I eat and try to control my cholesterol with a good ,healthy diet. I also have heard that Red Yeast Rice- available at GNC or Health food stores can lower your cholesterol. I might try that but for now I'm doing the healthy diet and exercise.

I also started taking Welchol, two in the morning and two in the evening. I started noticing that I can not get an erection, and I know it's the medication. Can someone out there tell me if i am the only one or is someone else having this problem due to Welchol?

Just started Welchol after trying Lipitor & others. Have now developed severe vertigo & my right upper arm is killing me. I can't drink ANY alcohol because it makes me violently ill, almost to the point of throwing up, My doc says this drug is non-systemic & says I should have a brain scan...I stopped taking it 3 days ago-arm pain is gone but not the vertigo yet...I'll have to weigh my options of going back on it again.
Has anyone else had dizziness & lightheadedness from this?
