Does Technetium Tc 99m Oxidronate Interact with Iron Supplements?

Technetium Tc 99m Oxidronate and Iron Supplements have a moderate drug interaction according to U.S. FDA drug labeling data. High levels of iron may alter biodistribution of technetium Tc 99m oxidronate, reducing skeletal uptake and increasing extraosseous uptake, potentially degrading imaging quality. The mechanism involves high levels of iron cations alter radionuclide biodistribution. Patients taking both medications should consult their healthcare provider before starting, stopping, or changing the dosage of either drug. This information is based on official FDA drug labeling sourced from OpenFDA and the NIH National Library of Medicine.

How This Interaction Works

The interaction between Technetium Tc 99m Oxidronate and Iron Supplements occurs because high levels of iron cations alter radionuclide biodistribution. Clinically, this means high levels of iron may alter biodistribution of technetium tc 99m oxidronate, reducing skeletal uptake and increasing extraosseous uptake, potentially degrading imaging quality. This is classified as a moderate interaction. While it may not require stopping either medication, your healthcare provider should be aware you are taking both so they can monitor for potential effects and adjust treatment if necessary.

What To Tell Your Doctor or Pharmacist

If you are taking Technetium Tc 99m Oxidronate and your doctor is considering prescribing Iron Supplements (or vice versa), make sure to:
