What is rosuvastatin?
Rosuvastatin is in a group of drugs called HMG CoA reductase inhibitors, or "statins." Rosuvastatin reduces levels of "bad" cholesterol (low-density lipoprotein, or LDL) and triglycerides in the blood, while increasing levels of "good" cholesterol (high-density lipoprotein, or HDL).
Rosuvastatin is used to lower cholesterol and triglycerides (types of fat) in the blood and to slow the build-up of plaque (fatty deposits) in your blood vessels.
Rosuvastatin is also used to lower the risk of stroke, heart attack, and other heart complications in certain people with diabetes, coronary heart disease, or other risk factors.
Rosuvastatin is used in adults and children who are at least 8 years old.
Rosuvastatin may also be used for purposes not listed in this medication guide.

Rosuvastatin is usually taken once a day, with or without food. Take the medicine at the same time each day.
While using rosuvastatin, you may need frequent blood tests.
Keep using this medicine as directed, even if you feel well. High cholesterol usually has no symptoms. You may need to take rosuvastatin on a long-term basis.
You may need to stop using rosuvastatin for a short time if you have:

What should I avoid while taking rosuvastatin?
Avoid drinking alcohol. It can raise triglyceride levels and may increase your risk of liver damage.
Avoid using antacids without your doctor's advice. Use only the type of antacid your doctor recommends, and do not take it within 2 hours after taking rosuvastatin. Some antacids can make it harder for your body to absorb rosuvastatin.
Avoid eating foods that are high in fat or cholesterol. Rosuvastatin will not be as effective in lowering your cholesterol if you do not follow a cholesterol-lowering diet plan.
