Metformin, MRI with contrast dye.

Okay, so I have an MRI with a contrast dye next week. Both my GP and Diabetes nurse advised to stop the Metformin at least 24 hrs before, and use Sitagliptin as a substitute if my sugars were a bit high.

However, checked with the radiologist today who said (paraphrased), "it's okay to continue with Metformin with the MRI contrast, but not with a CT, so you'll be fine."

Clearly I will take the ultimate advice from the consultant who referred me, but just though I'd ask if anyone has had an MRI with contrast recently?

Cheers,

Paul
 
I have had both in the past year with the CT contrast it can have an effect on kidney function which is why you stop metformin and do not restart until your kidney function is tested. When I had the MRI I didn't have to stop metformin as it is a different contrast used.
