Some iron preparations can trigger anaphylaxis in patients with certain allergies. Serious hypersensitivity including anaphylactic reactions have been reported with the use of high molecular weight iron dextran for intravenous iron infusions. [12] The use of high molecular weight iron dextran has now been abandoned.
Iron preparation is the formulation for iron supplements indicated in prophylaxis and treatment of iron-deficiency anemia. Examples of iron preparation include ferrous sulfate, ferrous gluconate, and ferrous fumarate. It can be administered orally, and by intravenous injection, or intramuscular injection.

Side effects of therapy with oral iron are most often diarrhea or constipation and epigastric abdominal discomfort. Taken after a meal, side effects decrease, but there is an increased risk of interaction with other substances. Side effects are dose-dependent, and the dose may be adjusted. The patient may notice that their stools become black.
Dextran is used in the osmotic stress technique for applying osmotic pressure to biological molecules. It is also used in some size-exclusion chromatography matrices; an example is Sephadex. Dextran has also been used in bead form to aid in bioreactor applications. Dextran has been used as an immobilization agent in biosensors.
It replaced iron dextran, which had been in use in the US since the 1900s, as a treatment for iron deficiency. Iron dextran was only used for extremely high risk situations, because it released enough iron at once to be toxic to the body. Further development of iron dextran was able to lower these reactions, but also caused more severe ...
Cosmofer is a treatment for iron deficiency anemia. The generic name of Cosmofer is low molecular weight iron dextran. Cosmofer was approved in 2001, and is available in more than 45 countries worldwide. It has a lower incidence of dextran-induced analphylaxis than older dextran-based products, although still requires a test dose. [12]
Dextran 70 is a type of fluid given by injection into a vein to expand blood volume. [1] Specifically it is used for shock such as that caused by bleeding or burns when blood transfusions are not quickly available. [2] However, it does not carry oxygen. [2] Common side effects include vomiting, fever, and joint pains. [2]
Injection site reactions (ISRs) are reactions that occur at the site of injection of a drug. They may be mild or severe and may or may not require medical intervention. Some reactions may appear immediately after injection, and some may be delayed. [1] Such reactions can occur with subcutaneous, intramuscular, or intravenous administration.
