What it is used for
- High cholesterol
- Lowering the risk of heart attack and stroke
- Heart and blood-vessel disease prevention in higher-risk people
How it works
Atorvastatin reduces how much cholesterol the liver makes by blocking a key enzyme. This lowers harmful LDL cholesterol in the blood and helps slow the build-up of fatty deposits in arteries, reducing the risk of heart attack and stroke.
How it is taken
Taken by mouth as a tablet, usually once a day, and it can be taken at any time of day with or without food. Take it exactly as your doctor or pharmacist directs and follow the label, and continue a heart-healthy diet. Do not stop on your own, as cholesterol and risk usually rise again.
No doses here on purpose. The right strength and schedule depend on you — only a doctor or pharmacist should set them. Always follow your prescription and the label.
