Atorvastatin: What’s the Real Deal With Side Effects? 15 Things You Should Know
Atorvastatin is a commonly prescribed statin used to lower LDL (“bad”) cholesterol and reduce the risk of heart attack and stroke. Like all medicines, it can cause side effects, but many people take it without serious problems.
A key point: do not stop atorvastatin on your own if you notice a possible side effect. Your healthcare provider can help determine whether symptoms are related to the medication and whether a change is needed.
