Atorvastatin (atorvastatin calcium) — Uses, Dosage, Side Effects & Safety

Drug class: HMG-CoA reductase inhibitor (statin)

Overview

Atorvastatin is a prescription medication used to lower cholesterol and triglyceride levels in the blood. It is commonly prescribed to reduce the risk of heart attack, stroke, and other cardiovascular complications in people with high cholesterol, diabetes, or other risk factors. Atorvastatin works by blocking an enzyme (HMG-CoA reductase) in the liver that is responsible for making cholesterol. By lowering 'bad' LDL cholesterol and raising 'good' HDL cholesterol, it helps prevent the buildup of fatty deposits in blood vessels. Key points for patients: Take atorvastatin as directed, usually once daily. It is most effective when combined with a healthy diet, regular exercise, and lifestyle changes. Regular blood tests may be needed to monitor cholesterol levels and liver function.
