Benefits of Iron Infusions: What to Expect From Your Treatment
If you’ve been feeling constantly tired, light-headed, or just ‘off’, you’re not imagining it. Low iron can insidiously affect every aspect of your life, from energy and mobility to focus and motivation. Many patients arrive at Narangba Station Medical Centre after months or even years of suffering through these symptoms, trying supplements and dietary changes with little to no relief.
If this sounds like you, you’re not alone. Iron deficiency is more common than you might think, and can take a major toll on your energy, mood and overall well-being.
If you think you may benefit from an iron infusion (or aren’t sure whether your symptoms may be related to low iron), book an appointment with our experienced GPs to assess your needs and recommend the most suitable treatment.
Let’s walk you through the benefits of iron infusions, what to expect from the treatment process, who might need an iron infusion and how long it typically takes to start feeling the effects, so you can make informed decisions about your health.

An iron infusion treatment is where iron is given directly into your bloodstream using an IV drip. Rather than relying on your stomach to absorb iron from food or tablets, the infusion allows your body to get a concentrated dose which it can use immediately. This can be useful when your iron levels are very low, when tablets haven’t worked for you, or when you need your levels corrected more quickly.
IV iron replenishes the iron that your body uses to make haemoglobin, the protein in red blood cells which carries oxygen. As your stores are replenished, your body is able to slowly rebuild healthy red blood cells, which is why you start to feel better in terms of symptoms like fatigue, breathlessness and brain fog.
Iron infusions are not just for the chronically tired, they are reserved for when you’re low enough to be impacting your health, or when other methods have failed. We’ve listed some common scenarios to help you see when your GP will judge an iron infusion to be the safest and most effective way forward.
Iron Deficiency That Isn’t Improving With Diet or Tablets
You may do everything by the book (eating iron-rich foods, taking iron supplements), yet your ferritin levels don’t budge or they rise very slowly. This can happen if your body needs a bigger boost of iron than your diet can provide, or if your stores are so low that even tablets can’t give you enough iron fast enough. An infusion is a faster and more reliable method for replenishing your body’s iron reserves and relieving the symptoms of fatigue, shortness of breath, brain fog and more.
Anaemia That Requires Rapid Correction
When your iron deficiency is severe enough to be diagnosed as moderate or severe anaemia, your body is struggling to get by on a low haemoglobin count. Anaemia symptoms like dizziness, shortness of breath, rapid heartbeats and pale skin can be especially disruptive to your day-to-day life and health. An infusion is the fastest way to get haemoglobin back to a healthy level so you can start to feel like yourself again.
When Oral Iron Causes Side Effects or Isn’t Absorbed Well
Iron tablets are the first treatment of choice, but they’re not suitable for everyone. For some people, they cause stomach upset, nausea, constipation or they’re just not tolerable as a daily treatment. Others have absorption problems due to gut inflammation, coeliac disease, gastric surgery or medications that affect absorption.
Infusions are a great option for these people since the treatment bypasses the gut entirely and delivers iron directly into the bloodstream for your body to use.
Chronic Conditions That Affect Iron Levels
Certain chronic health conditions cause ongoing or recurrent low iron levels in the body. Heavy periods, inflammatory bowel disease, kidney disease and heart failure are all examples of this. In these situations an infusion may be necessary to replenish stores and support the body, either because it’s losing iron faster than it can be replaced, or because inflammation and gut damage is interfering with how well your body can absorb iron from tablets. Iron infusions offer a reliable way to keep on top of iron levels and prevent anaemia symptoms from returning.
Iron Deficiency During Pregnancy
Your iron requirements increase dramatically during pregnancy, and tablets may not kick in quickly enough to support your changing body, especially during the second or third trimester.
Low iron during pregnancy can leave you feeling exhausted, and can potentially impact your baby’s growth if it becomes severe. For some women, an infusion is the safest and most effective method for correcting a deficiency without the stomach upsets that tablets are likely to cause.
The predictability of iron infusions and the speed with which iron stores can be replenished can make a significant and tangible difference to day-to-day life. Many patients describe a gradual improvement in energy levels, mental acuity and ability to “keep pace” with day-to-day activities, without the persistent tiredness and exhaustion that characterises iron deficiency.
The fact that iron is administered directly into the bloodstream means that the treatment is predictable. Clinicians can deliver a carefully-calculated dose that rapidly top-ups stores, replenishing the iron that your body needs to rebuild haemoglobin and transport oxygen efficiently, without the unpleasant side-effects that sometimes accompany oral iron.
Intravenous iron is also effective because it can often be administered in a single dose. Treatment only takes one appointment, so there is no need to commit to ongoing supplementation, making it easy to adhere to the treatment plan and see the benefits.
Iron infusions may also promote long-term health and well-being when used as part of a follow-up care plan. Your GP can check your iron levels and schedule a top-up dose if necessary, and advise on any underlying causes of deficiency so that treatment has a long-lasting, rather than a temporary, impact.
If you are about to have your first iron infusion, it’s natural to feel a little apprehensive and uncertain about what’s in store. Most people worry that it will be a far more involved process than it really is. In fact, the whole experience is very low-key, simple and you are in a safe environment with caring and competent staff every step of the way. It helps to know what to expect so the whole experience doesn’t seem so daunting on the day.
Below is a guide of what to expect from your first appointment for an iron infusion at our clinic.
Step 1: Pre-Treatment Consultation
Your GP or nurse will review your recent blood results (e.g. ferritin, haemoglobin and transferrin saturation) and confirm the need for iron infusion. They will also discuss your medical history and ask about any prior reactions to iron, current medications, and whether you are pregnant or breastfeeding.
All of this information is used to determine the appropriate type and dose of iron to be used, to ensure the treatment is safe and as effective as possible. The expected benefits of iron infusion are discussed, and you are given the opportunity to ask any questions and have any concerns addressed.
Step 2: Getting Ready for the Infusion
On the day of your infusion, you will be shown to the treatment area and made comfortable in a recliner chair. Your nurse will confirm your blood pressure, pulse, that you have had something to eat and that you are well enough for the infusion to go ahead. You will be walked through the process so you are not left wondering what will happen next. Behind the scenes, your iron dose will be double-checked; it’s a simple but vital safety measure.
Step 3: IV Cannula Placement
The next step is insertion of the cannula (the small tube that stays in your vein to deliver the iron). The cannula will be placed in your forearm or the back of your hand. This is often described as a quick, sharp pinch but it subsides almost immediately. The cannula is then taped in place so you don’t need to think about it again.
Step 4: The Infusion
At this point, the iron solution will be connected to the cannula and the infusion will be started. Depending on the iron formulation used, the infusion may take approximately 15 minutes to nearly an hour. You may experience a few minor sensations which are harmless and subside within a few minutes, such as a warming sensation, a feeling of heaviness around the arm where the infusion is, and/or a fleeting metallic taste in your mouth.
Nurses will check your blood pressure during the infusion and ensure you are feeling comfortable. Most people spend this time on their phone or tablet, reading, or just relaxing.
Step 5: Observation and Aftercare
After the infusion is complete, you will be asked to sit for a short observation period of around 20 to 30 minutes, just to ensure you are feeling ok. Most people feel fine and are able to drive themselves home. You will be advised of mild side effects to look out for in the next day or so, such as temporary fatigue and slight tenderness around the cannula site.
Step 6: Follow-Up and Results
Iron infusion works over time, and you won’t feel any better immediately. It takes time for your body to use the iron to make more haemoglobin, restore your levels and for you to begin to feel the benefit of this. Some people feel more energetic within a week, for others it’s more gradual over a few weeks.
The follow-up of an iron infusion will typically include further blood tests organised by your GP, to check that:
- Iron stores have increased.
- Haemoglobin is responding.
- You may need another infusion.
Your GP will also investigate the underlying cause of your low iron to try to avoid repeated cycles of fatigue in the future.
While your body slowly replaces iron stores and haemoglobin, most people start to experience some of the changes in their day-to-day lives before their follow-up blood tests. They might realise it's not as hard to climb the stairs, they're able to focus better at work or their regular mid-afternoon dip isn't as severe.
Mood and motivation can also start to change subtly. Activities that previously felt like a huge effort suddenly feel easier, brain fog may lift just enough for you to feel more able to think and be in the moment. It's these small changes that will often occur before the big surge in energy levels which will continue to build over the coming weeks.
It's different for everyone, and factors like the severity of the deficiency, sleep quality, diet and overall health will all play a role. Keeping a record of how you're feeling as these changes occur will help your GP see how well the infusion has worked and whether or not any changes are needed in future treatment.
Iron Infusions vs Oral Iron
When deciding how to treat iron deficiency, it can help to understand the practical differences between oral iron tablets and intravenous iron infusions. Both have a role, but the best choice depends on your iron levels, how quickly you need results, and how well your body tolerates oral supplements.
The table below gives a clear comparison to help you see how each option works in everyday life.

Choosing the right clinic for you means finding a place where qualified GPs and nurses understand the nuances of iron deficiency, can monitor your treatment safely, and tailor the infusion to your individual needs. A clinic that prioritises patient comfort, thorough pre-treatment assessments, and careful follow-up will help you feel confident throughout the process.
- Depending on your specific treatment, an iron infusion may last between 15 minutes and 1 hour. Add a little extra time for a short period of observation after your infusion and ensure you have enough time in your schedule to avoid feeling rushed.
- Have a small snack and some water before your appointment to help prevent feeling light-headed or dizzy during your infusion. Avoid heavy or fatty foods immediately before your appointment.
- Bring any relevant patient information, like recent blood test results, along with a list of current medications and any previous reactions to iron or other infusions to help your GP or nurse tailor your treatment plan to your needs.
- Sleeves that can be easily rolled up will make it easier for the nurse to access your vein and keep you more comfortable during your infusion.
- Many patients can resume normal daily activities after their infusion, but some may prefer to rest at home for a short time. If you are new to iron infusions, you may wish to schedule lighter activities for after your treatment and avoid heavy exercise.
- If you have concerns or uncertainties about the process, make a note of them. Your care team at Narangba Station Medical Centre is happy to explain your treatment plan so you can feel relaxed and ready for your infusion.
