Iron is available over the counter as a single entity supplement in an iron salt form or in combination with vitamin supplements and is commonly used in the treatment of anemias. [ 1 ] [ 2 ] Overdoses on iron can be categorized as unintentional ingestion which is predominantly associated with children or intentional ingestion involving suicide ...
Intravenous iron infusions can cause skin rash, hives, itchiness and flush. Skin staining and discolouration can occur at the site of infusion if the iron and saline solution leaks outside the vein into the surrounding tissue. [14] Skin discolouration can be semi-permanent or permanent.
In vitro assays have been developed to understand the risk that pre-clinical drug candidates might cause CRS and guide dosing for Phase I trials, and regulatory agencies expect to see results of such tests in investigational new drug applications. [2] [21] A modified Chandler loop model can be used as a preclinical tool to assess infusion ...
Since iron stores in the body are generally depleted, and there is a limit to what the body can process (about 2–6 mg/kg of body mass per day; i.e. for a 100 kg/220 lb man this is equal to a maximum dose of 200–600 mg/per day) without iron poisoning, this is a chronic therapy which may take 3–6 months.

It does not seem to be able to entirely shut down the iron transport process. Also, in situations where excess iron damages the intestinal lining itself (for instance, when children eat a large quantity of iron tablets produced for adult consumption), even more iron can enter the bloodstream and cause a potentially deadly syndrome of iron overload.
Iron overload (also known as haemochromatosis or hemochromatosis) is the abnormal and increased accumulation of total iron in the body, leading to organ damage. [1] The primary mechanism of organ damage is oxidative stress, as elevated intracellular iron levels increase free radical formation via the Fenton reaction.
Therefore, with frequent blood transfusions, iron builds up in the body over time. [2] This can enter the liver , heart , pancreas , and endocrine organs . [ 2 ] Free iron increases the production of oxygen radicals (mostly hydroxyl radicals ) that cause damage to cells (particularly their DNA ).
Iron sucrose is a type II complex, with two oxygen atoms bonded to each iron atom. [3] When used for medicinal purposes, the iron complex is polymerized and the sucrose molecules combined to form a larger polysaccharide. The number of polymerizations does not have to be the same as the number of sucrose molecules in the polysaccharide.
