Anemia, characterized by a deficiency in red blood cells or hemoglobin, affects millions worldwide, leading to fatigue, weakness, and a diminished quality of life. Iron infusions offer a direct and rapid method to replenish iron levels, particularly for those who cannot tolerate or absorb oral iron supplements effectively. This article delves into the benefits, procedure, side effects, and other essential aspects of iron infusions.
What is an Iron Infusion?
An iron infusion is a medical procedure in which iron is delivered directly into your bloodstream through a vein, also known as intravenous (IV) infusion. A healthcare professional uses a needle to insert a small tube, called a catheter, into a vein, usually in your arm or hand. The catheter is connected to a long tube which is connected to an IV bag of iron diluted with a saline solution. This solution is then slowly dripped into your vein. This method bypasses the digestive system, making it ideal for people who cannot absorb iron efficiently from food or oral supplements.
Why are Iron Infusions Necessary?
Doctors usually treat iron deficiency anemia with dietary changes and iron supplement pills. However, in some cases, doctors may recommend iron infusions instead. This is often considered when:
- You can’t take iron by mouth.
- You can’t absorb iron adequately through the gut due to conditions like inflammatory bowel disease or celiac disease.
- You can’t absorb enough iron due to blood loss, such as from ulcers or heavy menstrual periods.
- You need to increase iron levels fast to avoid medical complications or a blood transfusion, such as before surgery or during pregnancy.
Iron infusions help increase the body’s iron levels more quickly than supplements or dietary changes. This can be helpful in situations where anemia is severe.
Preparing for an Iron Infusion
A doctor will give you specific instructions for preparing for your first iron infusion treatment. Some things you can do to prepare on the day of your infusion include:

- Eating breakfast and lunch, as there is no need to fast for an iron infusion.
- Taking regular medications.
- Being prepared to have a small IV drip put in your arm or hand.
Discussing the procedure with a doctor can help reduce anxieties. They can recommend ways to help you stay comfortable and relaxed during the procedure.
The Iron Infusion Procedure
An iron infusion usually takes place at a hospital or hemodialysis center. The procedure involves the following steps:
- Insertion of Catheter: A doctor or nurse inserts a small tube (catheter) into a vein, typically in your arm or hand.
- Administration of Iron Solution: The catheter is attached to an IV bag containing iron that has been diluted with a saline solution.
- Slow Infusion: The iron solution is either pumped into your vein or uses gravity to slowly drip down the tube and into your vein.
- Monitoring: The doctor performing the procedure will give you a test dose first to ensure you don’t have any adverse reactions from the iron. If you do, they will stop the procedure. During the procedure, your vital signs and IV line will be checked by a nurse and for 30 minutes after it has finished.
The infusion can take up to 3 or 4 hours. It often takes several iron infusions to bring the body’s iron levels to the appropriate levels. You may receive infusions over one or a few weeks for your treatments.
Benefits of Iron Infusions
Iron infusions offer several benefits, especially when oral iron supplements are not effective or well-tolerated.
Rapid Replenishment of Iron Levels
Iron infusions provide a direct and rapid increase in iron levels in the body. By delivering iron directly into the bloodstream, the body can quickly access and utilize the iron for red blood cell production and hemoglobin synthesis. This immediate availability is particularly crucial for individuals with severe iron deficiency anemia who need a quick boost in their iron levels.

Effective Treatment for Severe Iron Deficiency
Iron infusions are particularly effective in cases of severe iron deficiency anemia, where dietary iron supplementation alone may not be sufficient. The infusions bypass the digestive system, ensuring that the iron is fully absorbed and utilized by the body.
Improved Tolerance and Compliance
Many individuals experience adverse effects from oral iron supplements, such as nausea, constipation, or an upset stomach. Iron infusions bypass the digestive system, mitigating these side effects and improving tolerance. This can lead to better compliance with the treatment plan and more effective results.
Enhanced Absorption in Cases of Malabsorption
Certain medical conditions or gastrointestinal disorders can impair the body’s ability to absorb iron from the digestive system. Iron infusions can overcome these absorption challenges by directly delivering iron into the bloodstream.
Symptom Relief and Improved Quality of Life
Anemia can cause a range of debilitating symptoms, including fatigue, weakness, shortness of breath, and impaired exercise tolerance. By rapidly replenishing iron levels, iron infusions can alleviate these symptoms and significantly improve an individual’s quality of life. Many patients notice improvements in energy levels and symptoms within a few days to a week.
Iron Infusion vs. Iron Injection
Iron infusions involve delivering a dose of iron through the vein with an IV drip, while with an iron injection, a medical professional injects iron into a muscle with a needle. The injection is usually done into the buttocks. Iron infusions may take up to several hours, whereas iron injections deliver a whole dose immediately. Iron infusions tend to be less painful than iron injections. Injections can also cause intramuscular bleeding and orange discoloration. Because of these possible complications, doctors often favor iron infusions over iron injections to treat iron deficiency anemia.

Iron Infusions During Pregnancy
If you’re pregnant, your need for iron increases as the fetus develops. As the fetus absorbs iron from your body, iron levels may drop, resulting in anemia. For that reason, doctors sometimes order iron infusions for pregnant people. Infusions are often preferred over oral iron supplements because taking them by mouth can cause gastrointestinal side effects. However, iron infusions are usually reserved for the second or third trimester of pregnancy. It’s not yet known whether administering iron infusions during the first trimester is safe.
Potential Side Effects
While iron infusions are generally safe, it’s essential to be aware of potential side effects. Most side effects from iron infusions are mild. These include:
- Temporary changes in the way you taste food and drinks
- Headaches
- Nausea and vomiting
- Muscle and joint pain
- Shortness of breath
- Itchiness and rash
- Increased or decreased blood pressure or heart rate
- Burning sensation or swelling at the site of the injection
Serious Side Effects
A rare but serious complication from iron infusions is iron toxicity. The symptoms of iron toxicity may come on quickly, which can cause anaphylactic shock. Or they may come on slowly over time. Healthcare professionals use a test dose and slow infusion rate to prevent this complication.
A doctor will use the test dose to monitor you for any reactions. These reactions can include:
- Anaphylaxis
- Shock
- Severe hypotension (low blood pressure)
- Collapse
- Loss of consciousness
Recovery After an Iron Infusion
You typically do not need to recover from an iron infusion. You can return to your daily activities when the infusion is complete. However, it is generally recommended to avoid intense physical activity for at least 24-48 hours after an iron infusion. Some patients may experience fatigue or dizziness, so light activities such as walking are usually fine.
Long-Term Effects and Maintenance
The physical benefits of an iron infusion include increased energy and easier breathing. You should start feeling these benefits a few weeks after your final infusion treatment. How long these benefits last depends on the cause of your iron deficiency anemia and whether or not you’re using any other therapies to increase your iron levels.
For example, regular blood loss, such as through menstruation, may lead to a chronic drop in iron levels. Depending on your situation, the benefits of an iron infusion may last anywhere from several months to a few years. A doctor may recommend additional iron-increasing therapies, such as supplementation and dietary changes, which can increase the iron your body absorbs from foods and prolong the benefits. Some patients may require periodic infusions to maintain healthy iron levels.
Cost of Iron Infusions
The cost of an iron infusion depends on what type you get, where you have the treatment, and how much your insurance covers. Each infusion can range in price from $400 to more than $4,300.
Addressing Reluctance Towards Iron Infusions
Some doctors are reluctant to give iron infusions because they worry about the risk of anaphylaxis and other serious side effects. In the past, some forms of IV iron were linked to serious reactions and even death. But newer iron formulations are much safer, and serious risks are rare. The person who gives you your iron infusion will monitor you and will treat it in the rare case that it does happen.
