No systematic interaction studies with<unk>  have been conducted. Food reduces its uptake from the gut, as do calcium and magnesium salts and tetracycline antibiotics. Conversely, iron inhibits the uptake of many drugs, such as bisphosphonates, tetracycline antibiotics, quinolone antibiotics, levothyroxin, and levodopa. Combining the drug with intravenous iron can result in fast release of iron into the blood, potentially leading to low blood pressure or even collapse. Dimercaprol in combination with iron is toxic for the kidneys. The antibiotic chloramphenicol interferes with incorporation of iron into red blood cells and with iron excretion. Furthermore, iron can reduce the blood pressure lowering effects of methyldopa.<unk>  is metabolized by the enzyme UGT1A6. It is not known whether inhibitors of this enzyme increase<unk>  concentrations in the body.
