Description: Iron dextran replaces the depleted iron stores in the bone marrow where it is used in the synthesis of haemoglobin for the treatment of iron-deficiency anaemia where oral therapy is ineffective or impracticable.

This medication is used to treat “iron-poor” blood (anemia) in people who cannot take iron by mouth or because their anemia has not been successfully treated by it. You may also need extra iron because of blood loss during kidney dialysis. Your body may need more iron if you use the drug erythropoietin to help make new red blood cells. Iron is an important part of your red blood cells and is needed to carry oxygen in the body.

How to use iron dextran injection

This medication is usually injected deep into the muscle of the buttock or slowly into a vein as directed by your doctor. When injecting into the buttock, the next injection is given on the opposite side from the last injection.

Before the first full dose, a smaller test dose is given slowly to check for possible allergic effects. If no reaction is seen after one hour, the full dose may be given. You will be checked carefully for reactions by a health care worker each time you are getting the iron.

Iron injections may be given once daily in small doses or as directed by your doctor. Large doses may be given in a solution and injected into a vein over several hours. Some side effects such as dizziness and flushing may be stopped by giving the drug more slowly. The dose and length of treatment is based on your age, weight, condition, and response to therapy. Your doctor will order blood tests to monitor your response.

If you are giving this medication to yourself at home, learn all preparation and usage instructions from your health care professional. Before using, check this product visually for particles or discoloration. If either is present, do not use the liquid. Learn how to store and discard medical supplies safely.
