Atorvastatin is a prescription medicine in a group called statins. It is mainly used to lower LDL (“bad”) cholesterol and reduce the risk of cardiovascular problems such as heart attacks and strokes. MedlinePlus+1
How does it work?
Atorvastatin reduces the amount of cholesterol your liver produces and helps the liver remove more LDL cholesterol from the bloodstream. It can also lower triglycerides and modestly raise HDL (“good”) cholesterol. MedlinePlus
Why is it commonly prescribed?
Doctors commonly use it because it can:
-
Treat high LDL cholesterol
-
Reduce the buildup of cholesterol-containing plaque in arteries
-
Lower the risk of heart attack and stroke
-
Help protect people who already have cardiovascular disease or who have a sufficiently high risk of developing it MedlinePlus+1
It’s often prescribed alongside a heart-healthy diet, exercise, and other lifestyle measures.
Are there side effects?
Many people tolerate atorvastatin well. Possible effects include muscle aches, digestive symptoms, or headache. Rarely, statins can cause significant muscle injury or liver problems. They can also slightly increase the risk of type 2 diabetes, particularly in people who already have risk factors for diabetes. MedlinePlus+1
Important: Don’t stop atorvastatin on your own just because your cholesterol improves—the medication generally controls the risk rather than permanently curing the underlying tendency toward high cholesterol. MedlinePlus
If you’d like, I can also explain what atorvastatin 10 mg, 20 mg, or 40 mg means and when each dose is typically used.
