Mike,
I can't speak to Vytorin 10/40 but can as to Vytorin 10/20 in April 07.
Total=117, LDL=55, Tris=66, hdl=49.
I know everyone. Numbers to die for

but the side effects were not so good; muscle aches, sore, dizzy, low testosterone (I think), etc. I think there is something to be said for the argument that we need some cholesterol and too little can be dangerous just as too much (can be).
Regardless, I would advise you against adding onto the Vytorin 10/40. You are taking two drugs for cholesterol lowering and piling on would seem risky.
good luck.
