Atorvastatin is a prescription medication that belongs to a group of drugs called statins. It is commonly prescribed to lower cholesterol and reduce the risk of heart disease and stroke.
Doctors often prescribe atorvastatin because it helps:
- Lower LDL (“bad”) cholesterol, which can build up in artery walls.
- Lower triglycerides, another type of fat in the blood.
- Slightly increase HDL (“good”) cholesterol, which helps remove excess cholesterol from the bloodstream.
Why is it commonly prescribed?
Atorvastatin is frequently recommended for people who:
- Have high LDL cholesterol.
- Have already had a heart attack, stroke, or certain heart procedures.
- Have diabetes (especially if they’re at higher risk of cardiovascular disease).
- Have multiple risk factors for heart disease, such as high blood pressure, smoking, or a strong family history.
- Have inherited conditions that cause very high cholesterol levels.
How does it work?
Your liver makes most of the cholesterol in your body. Atorvastatin works by blocking an enzyme involved in cholesterol production. As a result, the liver produces less cholesterol and removes more LDL cholesterol from the blood.
How is it taken?
- Usually once a day, with or without food.
- It’s important to take it consistently, as prescribed.
- A healthy diet, regular exercise, and other lifestyle changes are still important while taking the medication.
Possible side effects
Most people tolerate atorvastatin well. Common side effects may include:
- Muscle aches or soreness
- Joint pain
- Mild digestive upset (such as nausea or diarrhea)
- Headache
Rare but more serious side effects include:
- Severe muscle pain or weakness (which should be reported promptly)
- Liver problems, which may require monitoring in some people
Things to keep in mind
- Avoid drinking large amounts of grapefruit juice, as it can increase atorvastatin levels in your body and raise the risk of side effects.
- Tell your healthcare provider about all medications and supplements you take, since some can interact with atorvastatin.
- Atorvastatin is generally not recommended during pregnancy.
If you’ve been prescribed atorvastatin, your healthcare provider may periodically check your cholesterol levels and, if needed, other blood tests to make sure the medication is working effectively and safely.
