Crestor is the brand name for rosuvastatin, a prescription drug used to treat high cholesterol levels.
Crestor is in a class of drugs known as statins, which slow the buildup of plaque in your arteries and reduce your levels of âbadâ cholesterol (LDL or low-density lipoprotein) and triglycerides in the blood.
At the same time, Crestor increases HDL or high-density lipoprotein levels, also known as âgoodâ cholesterol.
There is no generic form of Crestor currently available to consumers. The drug was approved by the Food and Drug Administration (FDA) in 2003 and is manufactured by AstraZeneca.
Your doctor may prescribe Crestor to lower your risk of stroke, heart attack, or other cardiac complications, which can occur in those who have diabetes, coronary heart disease, or other risk factors.
Using Crestor alone is not enough: You will also have to eat a healthy diet and make other lifestyle changes like exercising, quitting smoking, and maintaining a healthy weight.
Even if you make all of these lifestyle changes, it may still take up to four weeks before you get the full benefit of Crestor.

In some rare cases, people using Crestor have developed a disorder in which muscle tissue breaks down, resulting in kidney failure.
This is more likely to happen if you are older or if you have kidney disease or an underactive thyroid (hypothyroidism) that is poorly controlled.
