When to contact a doctor promptly
Seek medical advice if you develop:

These can indicate uncommon but potentially serious complications.
Important perspective
For people at increased cardiovascular risk, the benefits of atorvastatin in reducing heart attacks and strokes often outweigh the risks of side effects. Many symptoms attributed to statins may also be caused by aging, other medications, or unrelated medical conditions.
Don’t stop atorvastatin without medical advice
Stopping a statin suddenly can increase cardiovascular risk in some people. If you think you’re experiencing side effects, it’s generally better to discuss them with your healthcare professional, who may:
- Adjust the dose
- Switch to another statin
- Investigate other possible causes
If you’re taking atorvastatin and have specific symptoms, tell me:
- Your age
- Your dose (e.g., 10 mg, 20 mg, 40 mg, 80 mg)
- The symptoms you’re experiencing
and I can help you understand whether they’re commonly associated with the medication.
