Atorvastatin is a prescription medication in the statin family. It is commonly used to lower cholesterol and reduce the risk of heart attacks, strokes, and other cardiovascular problems.
How atorvastatin works
Your liver produces cholesterol. Atorvastatin blocks an enzyme involved in that process, which helps:
- Lower LDL (“bad”) cholesterol
- Lower triglycerides
- Modestly raise HDL (“good”) cholesterol
- Reduce plaque buildup in arteries over time
Why doctors prescribe it
1. High cholesterol
Many people take atorvastatin to lower elevated LDL cholesterol levels.
2. Prevention of heart attacks and strokes
Doctors often prescribe it to people who have:
- Existing heart disease
- Diabetes
- Multiple cardiovascular risk factors
- A history of stroke or heart attack
3. Cardiovascular disease
It helps reduce the risk of complications from atherosclerosis (hardening and narrowing of the arteries).
Common side effects
Most people tolerate atorvastatin well, but possible side effects include:
- Muscle aches or soreness
- Joint pain
- Mild digestive upset
- Headache
Serious side effects are uncommon but can occur.
Important considerations
- Take it exactly as prescribed.
- Do not stop it without discussing it with your healthcare provider.
- Your doctor may periodically check cholesterol levels and, in some cases, liver function.
When to contact a doctor
Seek medical advice if you develop:
- Severe muscle pain or weakness
- Dark-colored urine
- Signs of liver problems (such as yellowing of the skin or eyes)
Bottom line
Atorvastatin is one of the most commonly prescribed cholesterol-lowering medications because it has been shown to reduce the risk of major cardiovascular events in many people. For those at elevated cardiovascular risk, its benefits often outweigh the potential side effects.
