What Is Atorvastatin and Why Is It Commonly Prescribed? 15 Possible Side Effects You Should Know About

What is atorvastatin?

Atorvastatin is a medication in the group called statins. It is commonly prescribed to help lower LDL (“bad”) cholesterol and reduce the risk of serious cardiovascular events such as heart attacks and strokes.

It works by reducing the liver’s production of cholesterol and helping the body remove more LDL cholesterol from the blood.

Why is atorvastatin prescribed?

Doctors may recommend atorvastatin for people who have:

• High LDL cholesterol
• A history of heart attack or stroke
• Coronary artery disease
• Diabetes with increased cardiovascular risk
• A higher-than-average risk of developing heart disease

Lowering cholesterol can help slow the buildup of fatty deposits (plaque) in arteries and reduce future cardiovascular risk.
