Why is this medication prescribed?

Rosuvastatin is used together with lifestyle changes (diet, weight-loss, exercise) to reduce the amount of cholesterol (a fat-like substance) and other fatty substances in your blood. Rosuvastatin is in a class of medications called HMG-CoA reductase inhibitors (statins). It works by slowing the production of cholesterol in the body.

Buildup of cholesterol and other fats along the walls of the blood vessels (a process known as atherosclerosis) decreases blood flow and, therefore, the oxygen supply to the heart, brain, and other parts of the body. Lowering blood levels of cholesterol and fats may help to decrease your chances of getting heart disease, angina (chest pain), strokes, and heart attacks. In addition to taking a cholesterol-lowering medication, making certain changes in your daily habits can also lower your cholesterol blood levels. You should eat a diet that is low in saturated fat and cholesterol (see SPECIAL DIETARY), exercise 30 minutes on most, if not all, days and lose weight if you are overweight.

How should this medicine be used?

Rosuvastatin comes as a tablet to take by mouth. It is usually taken once a day with or without food. Take rosuvastatin 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 rosuvastatin exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.

Your doctor will probably start you on a low dose of rosuvastatin and gradually increase your dose, not more than once every 2-4 weeks.

Continue to take rosuvastatin even if you feel well. Do not stop taking rosuvastatin without talking to your doctor.
