Atorvastatin is a statin medication used to lower cholesterol and reduce the risk of heart attack and stroke. Most people take it without significant problems, but some side effects can be subtle and may not be immediately linked to the medication.
15 subtle side effects that can occur with atorvastatin

- Mild muscle pain or stiffness is one of the more common side effects.

Don’t stop atorvastatin on your own
If you think atorvastatin is causing side effects, do not stop taking it without speaking to the healthcare professional who prescribed it. For many people, the medication’s benefits in reducing the risk of heart attack and stroke outweigh the risk of side effects. If side effects occur, your clinician may recommend changing the dose, switching to a different statin, or trying another cholesterol-lowering medication.
If you’re taking atorvastatin and are concerned about a particular symptom, tell me:
- Your dose (for example, 10 mg, 20 mg, 40 mg, or 80 mg)
- How long you’ve been taking it
- What symptoms you’ve noticed and when they began
I can help you consider whether they could be related and what questions to discuss with your healthcare professional.
