Rosuvastatin 20 mg: Uses, Dosage, Side Effects, Safety, and Frequently Asked Questions

What Is Rosuvastatin 20 mg?

Rosuvastatin 20 mg is a prescription statin medication used to lower high cholesterol and reduce the risk of heart attack, stroke, and other cardiovascular events. It belongs to a class of medicines known as HMG-CoA reductase inhibitors, commonly called statins.

Rosuvastatin works by reducing the amount of cholesterol produced by the liver while increasing the liver’s ability to remove low-density lipoprotein (LDL) cholesterol, often referred to as “bad” cholesterol, from the bloodstream.

It is available in several strengths, including:

• 5 mg tablets
• 10 mg tablets
• 20 mg tablets
• 40 mg tablets

Rosuvastatin is also available under the brand name Crestor in many countries.
