Simvastatin is used together with diet to lower blood levels of "bad" cholesterol (low-density lipoprotein, or LDL), to increase levels of "good" cholesterol (high-density lipoprotein, or HDL), and to lower triglycerides (a type of fat in the blood).
Simvastatin is also used to lower the risk of stroke, heart attack, and other heart complications in people with diabetes, coronary heart disease, or other risk factors.
Simvastatin is used in adults and children who are at least 10 years old.
Simvastatin may also be used for purposes not listed in this medication guide.

You should not take simvastatin if you are allergic to it, or if:
- you have active liver disease; or

Some medicines can cause unwanted or dangerous effects when used with simvastatin. Your doctor may change your treatment plan if you also use medicine such as:
- cyclosporine;
- danazol;
- gemfibrozil;
- imatinib;
- lomitapide;
- nefazodone;
- an antibiotic or antifungal medicine;

Tell your doctor if you have ever had:

- kidney disease;
- diabetes;
- a thyroid disorder;
- if you are of Asian descent; or
- if you drink more than 2 alcoholic beverages daily.
Simvastatin can cause a condition that results in the breakdown of skeletal muscle tissue, leading to kidney failure. This condition may be more likely to occur in older adults and in people who have kidney disease or poorly controlled hypothyroidism (underactive thyroid).
Do not use simvastatin if you are pregnant. It could harm the unborn baby or cause birth defects. Use effective birth control to prevent pregnancy while you are using this medicine. Stop taking simvastatin and tell your doctor right away if you become pregnant.
