What Is Atorvastatin and Why Is It Commonly Prescribed?
Atorvastatin is a statin—a medicine used to lower cholesterol and reduce the risk of heart attacks, strokes, and other cardiovascular diseases.
It works by blocking an enzyme in the liver that’s needed to make cholesterol. This lowers the amount of LDL (“bad”) cholesterol in the blood and helps reduce the buildup of fatty plaques in the arteries.
Why Is Atorvastatin Prescribed?
Your healthcare professional may prescribe atorvastatin to:
- Lower high LDL cholesterol
- Reduce the risk of heart attack and stroke
- Help prevent cardiovascular disease in people at high risk
- Treat people with existing heart disease
- Help manage inherited conditions that cause very high cholesterol
It is often recommended alongside lifestyle changes such as a heart-healthy diet, regular exercise, and not smoking.
How Is It Taken?
Atorvastatin is usually taken:
- Once a day
- With or without food
- At the same time each day, if possible
Unlike some older statins, atorvastatin does not have to be taken at night.
Common Side Effects
Many people have no side effects. When they do occur, they are often mild and may include:
- Muscle aches or soreness
- Headache
- Joint pain
- Mild digestive symptoms, such as nausea, diarrhoea, or constipation
Rare but Serious Side Effects
Contact your healthcare provider promptly if you develop:
- Severe or unexplained muscle pain, tenderness, or weakness, especially if accompanied by fever or dark-coloured urine
- Yellowing of the skin or eyes (jaundice)
- Severe abdominal pain
- Signs of an allergic reaction, such as swelling of the face, lips, tongue, or throat or difficulty breathing (seek emergency care)
Drug and Food Interactions
Some medicines can interact with atorvastatin, increasing the risk of side effects. Always tell your healthcare provider or pharmacist about all prescription medicines, over-the-counter medicines, and supplements you take.
Large amounts of grapefruit or grapefruit juice can increase atorvastatin levels in the body, so it’s generally recommended to avoid or limit grapefruit while taking this medication.
Can You Stop Taking It?
Do not stop atorvastatin without discussing it with your healthcare provider. Stopping treatment can allow cholesterol levels to rise again, increasing the risk of heart attack or stroke in people who benefit from the medication.
Who Benefits Most?
Atorvastatin is commonly prescribed for people who have:
- High LDL cholesterol
- Diabetes with an increased risk of cardiovascular disease
- A history of heart attack, stroke, or angina
- Peripheral artery disease
- A high calculated risk of developing cardiovascular disease over the next 10 years
