Atorvastatin is a prescription medication in a group of drugs called statins. It is commonly prescribed to help lower LDL (“bad”) cholesterol and reduce the risk of cardiovascular events such as heart attacks and strokes in people who may benefit from cholesterol-lowering treatment.
How does atorvastatin work?
Atorvastatin works by blocking an enzyme in the liver called HMG-CoA reductase, which plays a role in making cholesterol. By reducing cholesterol production, the liver removes more LDL cholesterol from the blood.
Why is it commonly prescribed?
Doctors may prescribe atorvastatin to help:
- Lower high LDL cholesterol
- Reduce the risk of heart attack and stroke in people with certain risk factors
- Slow the buildup of plaque in arteries (atherosclerosis) as part of a heart-health plan
- Manage cholesterol levels in people with conditions such as familial hypercholesterolemia (an inherited tendency toward very high cholesterol)
Common side effects
Many people take atorvastatin without major problems, but possible side effects can include:
- Muscle aches or soreness
- Headache
- Digestive symptoms such as nausea or diarrhea
- Mild increases in liver enzymes on blood tests
Rarely, statins can cause serious muscle injury or other complications, which should be discussed with a healthcare professional if symptoms occur.
Important things to know
- Take atorvastatin exactly as prescribed.
- Tell your healthcare provider about all medications, supplements, and herbal products you use because some can interact with it.
- Avoid or limit grapefruit products if your healthcare provider advises it, as grapefruit can affect how some medications are processed.
- Do not stop taking it suddenly without discussing it with your prescriber.
Bottom line
Atorvastatin is one of the most widely used cholesterol-lowering medications because it has strong evidence for reducing cardiovascular risk in appropriate patients. Whether someone should take it depends on their cholesterol levels, overall health, and individual risk factors.
