Contents of the pack and other information
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
For Position Only
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
a hereditary illness (homozygous familial
hypercholesterolaemia) that increases the
cholesterol level in your blood. You may also
receive other treatments.
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.

Warnings and precautions
Tell your doctor:
• about all your medical conditions including
• if you drink large amounts of alcohol.
• if you have ever had liver disease. ZOCOR
may not be right for you.
• if you are due to have an operation. You may
need to stop taking ZOCOR tablets for a
• if you are Asian, because a different dose
may be applicable to you.
Your doctor should do a blood test before you
start taking ZOCOR and if you have any symptoms
of liver problems while you take ZOCOR. This is to
check how well your liver is working.
Your doctor may also want you to have blood tests
to check how well your liver is working after you
start taking ZOCOR.
While you are on this medicine your doctor will
monitor you closely if you have diabetes or are at
risk of developing diabetes. You are likely to be at
risk of developing diabetes if you have high levels
of sugars and fats in your blood, are overweight and
have high blood pressure.
Tell your doctor if you have severe lung disease.
Contact your doctor immediately if you
experience unexplained muscle pain,
tenderness, or weakness. This is because on
rare occasions, muscle problems can be serious,
including muscle breakdown resulting in kidney
damage; and very rare deaths have occurred.
The risk of muscle breakdown is greater at higher
doses of ZOCOR, particularly the 80‑mg dose. The risk
of muscle breakdown is also greater in certain patients.
Talk with your doctor if any of the following applies:
• you consume large amounts of alcohol
• you have kidney problems
• you have thyroid problems
• you are 65 years or older
• you are female
• you have ever had muscle problems during
treatment with cholesterol-lowering
medicines called “statins” or fibrates
• you or a close family member have a
hereditary muscle disorder.
Also tell your doctor or pharmacist if you have a
muscle weakness that is constant. Additional tests and
medicines may be needed to diagnose and treat this.
Children and adolescents
Safety and effectiveness of ZOCOR have been
studied in 10-17 year old boys and in girls who had
started their menstrual period (menstruation) at
least one year before (see section 3: How to take
ZOCOR). ZOCOR has not been studied in children
under the age of 10 years. For more information,
talk to your doctor.
Other medicines and ZOCOR
Tell your doctor if you are taking, have recently taken
or might take any other medicine(s) with any of the
following active ingredients. Taking ZOCOR with any
of the following medicines can increase the risk of
muscle problems (some of these have already been
listed in the above section “Do not take ZOCOR”).
• If you need to take oral fusidic acid to
treat a bacterial infection you will need to
temporarily stop using this medicine. Your
doctor will tell you when it is safe to restart
ZOCOR. Taking ZOCOR with fusidic acid may
rarely lead to muscle weakness, tenderness or
pain (rhabdomyolysis). See more information
regarding rhabdomyolysis in section 4.
