Dr switched me back to 40mg simvastatin after taking 20mg lipitor (atorvastatin). Should I get off the Lipitor (atorvastatin) for a few days before starting simvastatin?

In brief: Not necessary

Simvastatin 40mg is similar in potency to 20mg of lipitor (atorvastatin).
There is no need to stop Lipitor (atorvastatin) for a few days before starting Simvastatin as they are similar drugs (both are statins). The Simvastatin can be started the day after stopping the Lipitor (atorvastatin) -- for most efficacy, take a statin at bedtime.

Ed -- go ahead and start the simvastatin the very next day -- it is like switching from Advil to Motrin -- no need to wait!

In brief: Yes

Very smart good question.
It depends how long you've been on lipitor (atorvastatin). 4-6 weeks should be ample time between them.
