Iron Infusions

What is an iron infusion and how will this help me?

The most common way to treat iron deficiency is to take iron by mouth as a tablet or liquid. This works for most people and is usually tried first. However, you might need an iron infusion if you:

• are not able to take iron tablets/liquids
• are not responding to iron tablets/liquids
• need to increase your iron levels quickly (e.g. before major surgery, late in pregnancy or to avoid a blood transfusion)
• have chronic kidney disease, chronic heart failure, or inflammatory bowel disease.

An intravenous (IV) iron infusion delivers iron directly into your bloodstream through a small cannula inserted into a vein, usually in your forearm. The iron is mixed with a saline solution and infused safely over 20–30 minutes. Iron infusions replenish iron levels faster than tablets or liquid supplements, and some people may require more than one infusion to restore their iron levels.

What are the common side effects? 

The following side effects can sometimes occur 1 to 2 days after the infusion:

• pain, redness and/or swelling at the site of administration
• muscle aches and/or bone pain
• headaches
• dizziness
• nausea and/or vomiting
• change in blood pressure

Most people experience no real side effects and if they do occur they are usually transient. But if they persist or are concerning you must return to your GP for review.

Physical benefits and improvement are usually felt within 1 – 2 weeks after having an iron infusion
