What med should not be given prior to a CT scan with contrast and for 48 hours after?

This question was on my complex care final, and I honestly for the life of me had no idea what the answer could have been. Maybe this is like a duh question and I just wasn't thinking.. but does anyone have any idea?
Look up your diabetes meds....

I believe Metformin

Quote from blondy2061hI believe Metformin

FYI, you'd better look at creatinine, too. We've had radiology refuse to do contrast based on the patient's labs...so, look up it's effect on kidney function (med listed above, and creatinine). If you understand the "why," you'll never forget the "what."

The answer is glucophage

Quote from core0Meformin should be stopped before contrast is given as in a CT scan due to the increased incidence of lactic acidosis. The answer the OP is looking for is Acetylcystine. The dose comes from this study among others:Prophylaxis of contrast-induced nephropathy in pat... [Catheter Cardiovasc Interv. 2003] - PubMed result

Hm, at my hospital we don't give Metformin for 48 hours after CT with contrast.

Holy hell, I would so fail the NCLEX if I had to take it again.

Quote from blondy2061hThe question was what would NOT be given, not what should be given.

We just had this one on our final too. Maybe you go to the same school The answer is in the textbook under the diabetes chapter
