Crestor 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).
Crestor is used to lower cholesterol and triglycerides (types of fat) in the blood.

Crestor is used in adults and children who are at least 10 years old.
