Intravenous Iron Infusions
Intravenous (IV) iron infusions are a quick and effective way to restore iron levels in your body, especially if you are iron deficient or preparing for surgery.
A single infusion can significantly improve iron stores within two weeks, and most patients feel better within a few days.
Iron Deficiency and Anaemia
Iron is required for the bone marrow to make red blood cells. When severe, iron deficiency can cause anaemia and tiredness even without anaemia.
Causes of iron deficiency
- a lack of iron in diet (meat is the best source of iron)
- poor absorption of iron from the gut
- bleeding
It is VERY important that the cause of the iron deficiency is investigated. In particular, bleeding needs to be excluded.
Frequently Asked Questions
Iron and surgery:
Adequate iron before surgery helps your body replace lost blood and can reduce the need for transfusions. IV iron is preferred if surgery is within four weeks, as tablets may not work fast enough.
Ways to replace iron:
- Diet: Meat, seafood, eggs, beans, lentils, vegetables, nuts, and fruit. Vitamin C improves absorption, while tea can reduce it.
- Oral tablets: Effective for many but may cause stomach upset or be poorly absorbed. Over-the-counter supplements often contain too little iron.
- IV iron: Quickly replenishes iron and works when tablets are insufficient or too slow.
The IV iron procedure:
- Iron (e.g., Iron Carboxymaltose/Ferinject) is given through a vein over 15 minutes.
- Nurses monitor your blood pressure, pulse, and temperature during the infusion.
- A repeat infusion may be given a week later if needed.
Possible side effects:
Most patients tolerate IV iron well, but some may experience:
- Headache, muscle aches, or fatigue.
- Flushing or vomiting.
- Rare skin staining if iron leaks outside the vein (prevented with a saline flush).
- Very rare serious reactions like breathing difficulties or low blood pressure.
Important notes:
- Minor aches and tiredness may occur for 24 hours after treatment.
- IV iron infusions are not covered by Medicare.
