Atorvastatin is a prescription medicine that belongs to a group of drugs called statins (or HMG-CoA reductase inhibitors). It is one of the most commonly prescribed cholesterol-lowering medicines worldwide.
Why is atorvastatin prescribed?
Doctors commonly prescribe it to:
- Lower LDL (“bad”) cholesterol
- Atorvastatin reduces the liver’s production of cholesterol and helps the body remove LDL cholesterol from the blood.
- Lowering LDL can slow the buildup of fatty plaques in arteries (atherosclerosis).
- Reduce the risk of heart attack and stroke
- It is often prescribed for people who have:
- Previous heart attack or stroke
- Coronary artery disease
- Diabetes with increased cardiovascular risk
- High cholesterol or other risk factors that raise the chance of cardiovascular disease
- It is often prescribed for people who have:
- Help stabilise artery plaques
- Statins may make fatty deposits in artery walls less likely to rupture, which can trigger blood clots and heart attacks.
How is it usually taken?
- Often taken once daily.
- It can usually be taken with or without food.
- The dose depends on cholesterol levels, overall heart risk, and treatment goals.
Possible side effects
Many people tolerate atorvastatin well, but possible side effects include:
- Muscle aches or weakness
- Headache
- Digestive symptoms (such as nausea or diarrhoea)
- Mild increases in liver enzymes on blood tests
Rare but important:
- Severe muscle pain, weakness, or dark urine can indicate a serious muscle reaction and should be checked promptly.
Common concerns
“Does atorvastatin damage the liver?”
Serious liver injury is rare. Doctors may check liver function before or during treatment if needed.
“Can I stop taking it if my cholesterol improves?”
Cholesterol often improves because the medicine is working. Stopping it without medical advice can allow cholesterol levels and cardiovascular risk to rise again.
