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 heart
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 medicine.
• Zocor is used in addition to your cholesterol–lowering diet if you have:
a raised cholesterol level in your blood (primary hypercholesterolaemia)
or elevated fat levels in your blood (mixed hyperlipidaemia)
• a hereditary illness (homozygous familial hypercholesterolaemia) that
increases the cholesterol level in your blood. You may also receive other
• 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
