Hi donanaliza,
Vytorin is a combination of Zocor and Zetia, so you've switched from
one statin to another. Side effects can worsen when switching statins
and/or increasing dosage. Intestinal discomfort is a common complaint
for all statins
Dr Graveline wrote an article about "Vytorin's Side Effects":
http://www.spacedoc.net/vytorin_side_effects.htm
There are several case histories of those experiencing side effects.
At the end of the page is a Vytorin update and a link to:
"Vytorin Concerns":
http://www.spacedoc.net/vytorin_concerns.htm
You might also want to order Dr Graveline's book:
"Statin Drug Side Effects and the Misguided War on Cholesterol"
If you are female, there is no evidence that statins benefit women
(or the elderly).
Do you have any other risks factors?
* diabetes
* over-weight
* high blood pressure
What were your cholesterol numbers before Lipitor?
* LDL
* HDL
* Triglycerides
