Atorvastatin is a prescription medication that belongs to a class of drugs called statins. It is commonly prescribed to lower cholesterol and reduce the risk of heart attacks and strokes.
What does atorvastatin do?
Atorvastatin works by blocking an enzyme in the liver that’s needed to make cholesterol. This helps:
- Lower LDL (“bad”) cholesterol
- Lower triglycerides
- Slightly raise HDL (“good”) cholesterol
Why is it prescribed?
Healthcare providers commonly prescribe atorvastatin to:
- Treat high LDL cholesterol (hypercholesterolemia)
- Help prevent heart attacks and strokes
- Reduce the risk of cardiovascular events in people with heart disease, diabetes, or other risk factors such as high blood pressure or smoking
- Help slow the progression of plaque buildup in the arteries (atherosclerosis)
How is it taken?
- Usually once daily, with or without food.
- It’s important to take it as prescribed and continue healthy habits such as eating a balanced diet, exercising, and avoiding smoking.
Common side effects
Many people take atorvastatin without significant problems. Possible side effects include:
- Muscle aches or soreness
- Joint pain
- Headache
- Mild digestive symptoms, such as nausea or diarrhea
Serious side effects (less common)
Seek medical attention promptly if you develop:
- Severe muscle pain or weakness, especially with fever or dark-colored urine
- Yellowing of the skin or eyes (jaundice)
- Severe allergic reactions, such as swelling of the face or difficulty breathing
Interactions
Atorvastatin can interact with certain medications and with large amounts of grapefruit or grapefruit juice, which may increase the risk of side effects. Always tell your healthcare provider about all medicines and supplements you take.
Regular blood tests may be recommended to monitor your cholesterol levels and, in some situations, your liver function. If you have questions about why atorvastatin was prescribed for you or concerns about side effects, discuss them with your healthcare provider before stopping the medication.
