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

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

Why Is Atorvastatin Prescribed?

Atorvastatin works by reducing the liver’s production of LDL cholesterol (“bad” cholesterol). Lowering LDL can help slow the buildup of fatty deposits (plaque) in blood vessels.

Doctors may prescribe it for people with:

• 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

It is often used along with healthy lifestyle habits, including a balanced diet, regular activity, and not smoking.
