I'm Taking Lipitor And Plavix. My Dr. Gave Me Another

I'm taking Lipitor and Plavix. My Dr. gave me another pill for cholesterol, can't remember the name , but even with my insurance it was going to cost me 270.00. I have Vytorin that I got in Mexico, can I take that with my other two pills. I did have 6 heart attacks and had a stint put in in early May.
