Hopefully you aren't driving because I'd say at least an hour before. There are new mri machines out there that don't cause that anxiety because they are open and quiet. I refused to schedule one except in an open mri.
Not sure it matters as far as the MRI is concerned.
I would say between 30 minutes to an hour and be sure to have someone drive you after.
I have to agree with kaismama and pamee... I would say about a half hr before if you are taking it to calm you to do the mri... Trust me I hate closed in Mri's and as kaismama stated they have the open one's and even though I am on klonopin I still go to the open one's I went to a closed one and they had to pull me out cause I couldn't deal with being enclosed like that... something you might want to consider for future... the open one's r so so much better and It doesn't even bother me to were I need to take something I am on klonopin for panic/ agoraphobia... if you do take the xanax try and get someone to drive you home... hope this helps..GOD BLESS...
Unfortunately, my MRI's have been/will be on my head so I can't do the open one. :( I took Xanax for the first one and will ask my psychiatrist tomorrow to prescribe that or valium.
