Contrast scan on Ozempic: what to tell scheduling, radiology and anesthesia

About this scan

Who to tell what

• Scheduler: I inject Ozempic once a week
• Radiology: my most recent eGFR, with its date, and any kidney disease
• Radiology: whether I take metformin
• Anesthesia (only if sedated): the date of my last Ozempic dose
• Anesthesia: any nausea, vomiting, bloating or early fullness this week
• My prescriber: whether any diabetes medicine changes around the procedure

From the ACR manual and the Ozempic label

• ACR: fasting is not required before routine intravascular contrast; with sedation, anesthesia guidelines apply.[1]
• ACR: IV saline prophylaxis is indicated with acute kidney injury or an eGFR below 30 (not on dialysis), may be considered at 30 to 44 in high-risk cases, and is not indicated for most others.[1]
• ACR: with an eGFR of 30 or above and no kidney injury, metformin does not need to stop for IV iodinated contrast, and metformin itself does not raise the risk of contrast kidney injury.[1]
• Ozempic label: rare aspiration under deep sedation or general anesthesia involved stomach contents despite fasting; data are insufficient to say whether pausing Ozempic lowers the risk.[2]
• Ozempic label: most reported acute kidney injury followed nausea, vomiting or diarrhea that caused dehydration.[2]
