Crestor (Rosuvastatin) Drug Information

  • Why is this medication prescribed?

    Crestor (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. Crestor (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?
