Atorvastatin Side Effects: 15 Possible Risks to Know About
Atorvastatin is a statin medication used to lower LDL cholesterol and reduce the risk of cardiovascular events such as heart attack and stroke in people who are likely to benefit from treatment. Like all medicines, it can cause side effects, although many people take it without serious problems.
The phrase “hidden dangers your doctor might not tell you about” can be misleading—healthcare professionals generally weigh both the benefits and risks of statins. However, it is useful to know what symptoms to watch for.
