Does Iopromide Interact with Metformin?
CDI records a major classification for Iopromide and Metformin. The stored summary is: Iodinated contrast agents increase risk of metformin-induced lactic acidosis, possibly by worsening renal function. Stop metformin at or prior to IOPROMIDE administration in patients with eGFR 30-60 mL/min/1.73 m2, hepatic impairment, alcoholism, heart failure, or intra-arterial contrast use. The mechanism involves worsening renal function. Patients taking both medications should consult their healthcare provider before starting, stopping, or changing the dosage of either drug. This record was extracted from drug labeling through openFDA. NIH/NLM RxNorm is used for drug identities. The summary and severity classification are CDI's processed information, not a verbatim source quotation. Product, route, and patient circumstances matter.

What To Tell Your Doctor or Pharmacist
If you are taking Iopromide and your doctor is considering prescribing Metformin (or vice versa), make sure to:
- Inform your doctor and pharmacist of all current medications, including over-the-counter drugs and supplements
- Ask whether the benefits of combining these medications outweigh the risks for your specific situation
- Ask what symptoms to watch for that would indicate the interaction is causing problems
- Ask how frequently you should be monitored while these are co-prescribed
- Ask whether any dosage adjustments are needed
- Never stop or change either medication without first consulting your healthcare provider
