WHY is this medicine prescribed?
Simvastatin is used together with diet, weight-loss, and exercise to reduce the amount of fatty substances such as low-density lipoprotein (LDL) cholesterol ('bad cholesterol') and triglycerides in the blood and to increase the amount of high-density lipoprotein (HDL) cholesterol ('good cholesterol') in the blood. Simvastatin may also be used to decrease the amount of cholesterol and other fatty substances in the blood in children and teenagers 10 to 17 years of age who have familial heterozygous hypercholesterolemia (an inherited condition in which cholesterol cannot be removed from the body normally). Simvastatin is also used to decrease the risk of heart attacks, strokes, and death, and to decrease the need for surgery to improve blood flow in people who have medical conditions that put them at high risk of developing heart and blood vessel problems. Simvastatin is in a class of medications called HMG-CoA reductase inhibitors (statins). It works by slowing the production of cholesterol in the body to decrease the amount of cholesterol that may build up on the walls of the arteries and block blood flow to the heart, brain, and other parts of the body.
HOW should this medicine be used?
Simvastatin comes as a tablet to take by mouth. It usually is taken once a day in the evening. Take simvastatin at around the same time every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take simvastatin exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Your doctor may start you on a low dose of simvastatin and gradually increase your dose, not more than once every 4 weeks.
Continue to take simvastatin even if you feel well. Do not stop taking simvastatin without talking to your doctor.
Are there OTHER USES for this medicine?
This medication may be prescribed for other uses; ask your doctor or pharmacist for more information.

Avoid foods with excess fat in them such as meat (especially liver and fatty meat), egg yolks, whole milk, cream, butter, shortening, pastries, cakes, cookies, gravy, peanut butter, chocolate, potato chips, coconut, cheese (other than cottage cheese), coconut oil, palm oil, and fried foods. Talk with your doctor or dietitian if you have any questions or would like more information about low-fat, low-cholesterol diets.
