Overview
Atorvastatin slows the liver's production of cholesterol. Lowering LDL cholesterol reduces the buildup of plaque in the arteries.
It works best alongside a heart-healthy diet, exercise, and not smoking.
What it's used for
- Lowering high LDL cholesterol and triglycerides
- Lowering the risk of heart attack and stroke in people with heart disease, diabetes, or other risk factors
How to take it
- Take it once a day, at any time of day, with or without food.
- Take it at the same time each day.
- Keep taking it even if you feel well. High cholesterol usually causes no symptoms.
Your dose depends on your health and other medicines. Always follow your prescription label, and ask your pharmacist if anything is unclear.
