What Is Atorvastatin and Why Is It Commonly Prescribed?
Atorvastatin is a prescription medicine belonging to a group called statins. It lowers “bad” LDL cholesterol and helps reduce the amount of cholesterol that can build up inside artery walls. It is commonly sold under the brand name Lipitor, as well as in generic form. (MedlinePlus)
Why do doctors prescribe it?
Atorvastatin may be prescribed to:
- Lower LDL (“bad”) cholesterol
- Lower triglycerides and, in some people, modestly increase HDL (“good”) cholesterol
- Reduce the risk of heart attacks and strokes
- Help protect people who already have cardiovascular disease or have a high risk of developing it. (MedlinePlus)
It works primarily by reducing cholesterol production in the liver and increasing the liver’s ability to remove LDL cholesterol from the blood. (MedlinePlus)
Is it only for people with high cholesterol?
No. A person may be prescribed atorvastatin even when their cholesterol isn’t extremely high if their overall cardiovascular risk makes treatment beneficial—for example, someone with established heart disease or certain other risk factors. (FDA Access Data)
What are the side effects?
Many people tolerate atorvastatin well. Possible side effects include digestive symptoms and joint pain. Muscle aches or weakness can occur, while serious muscle injury is rare. Liver problems are also uncommon but can be serious. (MedlinePlus)
Seek medical advice promptly if you develop unexplained severe muscle pain or weakness, dark urine, yellowing of the skin/eyes, or unusual extreme tiredness. (MedlinePlus)
What about grapefruit?
Grapefruit and grapefruit juice can interact with some statins, including atorvastatin. Ask your doctor or pharmacist how much is safe for you, particularly if you consume grapefruit regularly. (MedlinePlus)
One important point
Don’t stop atorvastatin simply because you feel well. High cholesterol usually causes no symptoms, and the purpose of treatment is often to reduce cardiovascular events over the long term. If you’re having side effects or want to stop, discuss alternatives or dose adjustments with your doctor rather than stopping it on your own. (MedlinePlus)
Bottom line: Atorvastatin is commonly prescribed because lowering LDL cholesterol can substantially reduce the risk of heart attack and stroke in people who are likely to benefit from statin therapy.
