Atorvastatin Side Effects: 15 Things to Know About This Medication 💊
Atorvastatin is a statin medication used to lower LDL (“bad”) cholesterol and reduce the risk of heart attack and stroke in people who need cholesterol management. Many people take it safely, but like all medicines, it can have side effects.
The phrase “hidden dangers doctors don’t tell you about” is often used online, but the reality is that potential risks are known and monitored by healthcare professionals.
