What happens if you experience liver damage from Lipitor?

If you experience liver damage or have concerns about Lipitor's potential risks, your doctor may recommend alternative medications, such as:
1. Pravastatin (Pravachol)
2. Simvastatin (Zocor)

4. Non-statin medications (e.g., Ezetimibe, bile acid sequestrants)
