Crestor (Rosuvastatin) Side Effects, Important Information, How to Take & More

Crestor is used to bring back the levels of cholesterol in the blood to normal levels.

How does Crestor work?

This drug works by lowering levels of bad cholesterol on the body. Bad cholesterol is low-density lipoprotein (LDL) that causes atherosclerosis which is a condition where thick layers of plaque build up on the inside walls of the arteries. As a result, arteries get narrower, and that increases the strain on the heart to pump blood throughout the body. Crestor also helps to increase the good cholesterol in the blood. Good cholesterol is high-density lipoprotein (HDL) that further helps to flush out other forms of cholesterol from the bloodstream that in turn, lowers the risk of associated heart diseases.
