Drug-interaction studies and post hoc analyses of Phase III studies showed no clinically relevant interaction of<unk>  with the systemic exposures to losartan, furosemide, omeprazole, digoxin, and warfarin, the lipid-lowering effects of statins, and oral vitamin D receptor agonists. According to the European label (Summary of Product Characteristics), medicinal products that are known to interact with iron (e.g. doxycycline) or have the potential to interact with Velphoro should be administered at least one hour before or two hours after Velphoro. This allows<unk>  to bind phosphate as intended and be excreted without coming into contact with medications in the gut that it might interact with. According to the US prescribing information, Velphoro should not be prescribed with oral levothyroxine. The combination of<unk>  and levothyroxine is contraindicated because<unk>  contains iron, which may cause levothyroxine to become insoluble in the gut, thereby preventing the intestinal absorption of levothyroxine.
