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. You should stay on a cholesterol-lowering diet while taking this medicine.
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 disease.
- Triglycerides are another form of fat in your blood that may increase your risk for heart disease.
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 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 measure your cholesterol with a simple blood test. Visit your doctor regularly, keep track of your cholesterol, and discuss your goals with your doctor.
How to take ZOCOR

Your doctor will determine the appropriate tablet strength for you, depending on your condition, your current treatment and your personal risk status.
Always take this medicine exactly as your doctor has told you. Check with your doctor or pharmacist if you are not sure. You should stay on a cholesterol-lowering diet while taking ZOCOR.
The recommended dose is ZOCOR 10 mg, 20 mg, or 40 mg by mouth once a day… Adults: The usual starting dose is 10, 20 or, in some cases, 40 mg a day. Your doctor may adjust your dose after at least 4 weeks to a maximum of 40 mg a day. Do not take more than 80 mg a day. Your doctor may prescribe lower doses, particularly if you are taking certain medicinal products or have certain kidney conditions.
The 80 mg dose is only recommended for adult patients with very high cholesterol levels and at high risk of heart disease problems who have not reached their cholesterol goal on lower doses.
