Iron Infusion 


What is an IV iron infusion?
Intravenous or IV means giving something directly into the blood stream
of the body through your vein.

Why is iron important?
Iron is essential for the body to make haemoglobin (Hb) - red blood cells,
which is important for carrying oxygen from your lungs to the rest of your
body. Low haemoglobin levels (also known as anaemia) make you
feel tired. Very low levels may require you to have a blood transfusion.

Why are you being given an iron infusion?
The most common way to treat iron deficiency anaemia is to take iron by mouth as a tablet or liquid. Intravenous
iron infusion is an alternative way of giving iron. IV iron infusion is given if you are:

  • Unable to tolerate iron taken by mouth
  • Unable to absorb iron through the gut.
  • In need of a rapid increase in iron levels to avoid complications or a blood transfusion.


Your colon must be completely empty of faecal material for the procedure to be thorough and safe. If it is not entirely clean certain areas may be obscured and the test may have to be repeated. Following the preparation, the return from your bowel should resemble urine (pale yellow). This will involve modifications to your diet. You will be given more specific instructions about this including a liquid diet for one to two days and the bowel preparation (laxative). Prior to your procedure it is important for your doctor to know your medical history and in particular any previous endoscopies. Bring a list of your current medication with you, together with any relevant x-rays or barium studies. Fully disclose any health problems you may have had as these may interfere with your colonoscopy, sedation or recovery. 

You should mention: 

  • An allergy or bad reaction to medicines or anaesthetics
  •  Taking medication to thin your blood including Warfarin, Dabigatran, Rivaroxaban, Aspirin or antiplatelet medication: e.g. Clopidogrel or Ticagrelor. Your doctor may ask you to stop taking these medications prior to your procedure or you may be given an alternative dose. 
  • Artificial hip or knee joints. 
  • Prolonged bleeding/clotting disorders or excessive bruising
  •  Diabetes – You must discuss this with your doctor or nurse before undertaking any period of fasting.
  •  Heart and lung problems including artificial heart valves and pacemakers.
  • Cardiac stents in the last 6 months. 
  • If you are pregnant or breast-feeding.
