1. WHAT ZOCOR IS AND WHAT IT IS USED FOR
ZOCOR contains the active substance simvastatin. ZOCOR is a
medicine used to lower levels of total cholesterol, ‘bad’ cholesterol (LDL
cholesterol), and fatty substances called triglycerides in the blood. In
addition, ZOCOR raises levels of ‘good’ cholesterol (HDL cholesterol).
ZOCOR is a member of the class of medicines called statins.
Cholesterol is one of several fatty substances found in the bloodstream.
Your total cholesterol is made up mainly of LDL and HDL cholesterol.
LDL cholesterol is often called ‘bad’ cholesterol because it can build up
in the walls of your arteries forming plaque. Eventually this plaque
build-up can lead to a narrowing of the arteries. This narrowing can
slow or block blood flow to vital organs such as the heart and brain.
This blocking of blood flow can result in a heart attack or stroke.
HDL cholesterol is often called ‘good’ cholesterol because it helps keep
the bad cholesterol from building up in the arteries and protects against
Triglycerides are another form of fat in your blood that may increase
your risk for heart disease.
You should stay on a cholesterol-lowering diet while taking this
ZOCOR is used in addition to your cholesterol–lowering diet if you

coronary heart disease (CHD) or are at high risk of CHD (because
you have diabetes, history of stroke, or other blood vessel disease).
ZOCOR may prolong your life by reducing the risk of heart disease
problems, regardless of the amount of cholesterol in your blood.
In most people, there are no immediate symptoms of high cholesterol.
Your doctor can measure your cholesterol with a simple blood test. Visit
your doctor regularly, keep track of your cholesterol, and discuss your
goals with your doctor.
