Summary

Iodinated contrast media can cause acute kidney injury, which can slow methotrexate elimination and cause toxicity. This matters most with high-dose methotrexate or in patients who already have impaired renal function.

What this interaction means in plain words

Ioversol and Methotrexate can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.

Evidence level: Low

Why it happens

Contrast-induced renal impairment reduces renal clearance of methotrexate.

What to do

Ensure adequate hydration and check renal function before and after contrast. With high-dose methotrexate, delay the contrast study or monitor methotrexate levels and blood counts.

What to ask your pharmacist

  • Should I take them at different times of day?
  • Does the dose of either medicine need to change?
  • Is there anything I should avoid, such as alcohol or certain foods, while on both?
