This page explains what happens if Atorvastatin and Simvastatin are taken together, according to official sources.
Duplicate statin

Immediately discontinue duplicated statin therapy. Only a single appropriately dosed statin should be prescribed under physician supervision.
Talk to your doctor or pharmacist about these two medicines; don't stop a prescribed medicine on your own.
