Iron is essential for energy, immune function, concentration, and producing the haemoglobin that carries oxygen through your blood. When iron levels fall low enough — through blood loss, poor absorption, high demand, or diet — the effects can be profound: exhaustion that sleep doesn't fix, brain fog, breathlessness, heart palpitations, hair loss, and more. Oral iron tablets can help, but they work slowly, are often poorly absorbed, and cause digestive side effects that make them hard to take consistently. When levels are very low, when oral iron isn't being absorbed well, or when symptoms are significantly affecting your life, an intravenous iron infusion can restore levels far more quickly and effectively. **Your doctor will have confirmed on blood tests that an infusion is appropriate for you. Common reasons include:** - Iron deficiency confirmed on blood tests, with oral iron not tolerated or not absorbed adequately - Heavy or prolonged uterine bleeding - Iron deficiency anaemia — where haemoglobin is also low - Perimenopause or postpartum iron depletion - Malabsorption conditions (e.g. coeliac disease, inflammatory bowel disease) - Significant fatigue or symptoms affecting daily function [ Book ](#book-11) #### **Before you come:** Collect Ferinject from your pharmacy and bring it to your appointment. Eat a high phosphate diet for 1–2 weeks beforehand. Allow 60 minutes for the appointment. ![Paint swirl – Pregnancy](https://outsidetheboxcare.com.au/files/images/Treated-Images/_3720x1650_crop_center-center_70_none_ffffff/13392/paint-swirl-1.webp) ### We use **Ferinject** **(ferric carboxymaltose)** The most widely used intravenous iron preparation in Australian general practice, PBS-subsidised, with a favourable safety profile and rapid effect. Most people notice improved energy within days to weeks of their infusion. ## The phosphate diet This part is more important than it sounds. Ferinject is highly effective — but it can temporarily lower your phosphate levels, a mineral your body needs for energy production, bone health, and muscle function. This is the most common side effect of this type of iron infusion, and it's worth understanding before your appointment. **Good sources of phosphate to include in your diet:** #### **Phosphate diet:** Dairy, meat, fish, eggs, nuts, seeds, legumes, and wholegrains. Start 1–2 weeks before and continue 1–2 weeks after. ![Icon Milk](https://outsidetheboxcare.com.au/files/images/Icons/Icons-Red/Icon-Milk.svg) #### **Dairy** Milk, yoghurt,cheese — particularly hard cheeses. Aim for 2–3 serves daily. ![Icon Fish](https://outsidetheboxcare.com.au/files/images/Icons/Icons-Red/Icon-Fish.svg) #### **Meat & Fish** Chicken, beef, pork, salmon, tuna, sardines. Good at most meals. ![Icon Nuts](https://outsidetheboxcare.com.au/files/images/Icons/Icons-Red/Icon-Nuts.svg) #### **Nuts & seeds** Pumpkin seeds, sunflower seeds, almonds, cashews. Great as snacks. --- ![Icon Legumes](https://outsidetheboxcare.com.au/files/images/Icons/Icons-Red/Icon-Legumes.svg) #### **Legumes** Lentils, chickpeas, kidney beans, edamame. Add to meals freely. ![Icon Bread](https://outsidetheboxcare.com.au/files/images/Icons/Icons-Red/Icon-Bread.svg) #### **Wholegrains** Wholegrain bread, oats, brown rice, bran cereals. Choose these over refined grains. ![Icon Eggs](https://outsidetheboxcare.com.au/files/images/Icons/Icons-Red/Icon-Eggs.svg) #### **Eggs** A reliable everyday source — yolk in particular is high in phosphate. ###### **What you need to know** ### Eat a high phosphate diet for 1–2 weeks before and after We recommend eating a diet rich in phosphate for **1–2 weeks before your infusion and 1–2 weeks afterwards**. This helps buffer the temporary drop that can occur after Ferinject and reduces the risk of symptoms like fatigue, weakness, and bone aches. Most people won't notice any problem — but for those who do, the symptoms can be surprisingly significant. A little dietary preparation goes a long way. ## Before your infusion What to do before you arrive. 1. **Collect your iron from the pharmacy.** Your doctor will have given you a script for Ferinject. Collect it from your pharmacy and bring it to your appointment – it should be stored at room temperature (not in the fridge). Do not open it. 2. **Start your high phosphate diet.** Begin eating phosphate-rich foods 1–2 weeks before your infusion appointment. See the food list above. 3. **Eat and drink normally beforehand.** Have a meal before you come — there is no need to fast. Stay well hydrated. 4. **Wear loose, comfortable clothing** with easy access to your arm – the cannula will be placed in a vein in your forearm or hand. 5. **Allow at least 60 minutes** for your appointment – the infusion runs for approximately 20–30 minutes, followed by a mandatory 30-minute observation period before you can leave. 6. **You may drive yourself home** unless you feel unwell. If you are concerned, bring someone with you. 7. Let us know if you have any **allergies**, particularly any previous reactions to iron infusions. 8. Please give at least **24 hours' notice** if you need to change or cancel – late cancellations will incur a fee. ![Fitness girls treated](https://outsidetheboxcare.com.au/files/images/Treated-Images/_2880x2880_crop_center-center_70_none_ffffff/10588/fitness-girls_treated.webp) ## On the day What happens step by step. Your infusion appointment is straightforward. Here is what to expect from the moment you arrive: 1. You arrive and hand over your Ferinject — your clinician will check the vial and confirm the dose calculated for your weight and blood results. 2. Your clinician will review your consent form, confirm your allergies, and answer any questions before the procedure begins. 3. **A small cannula is placed in a vein in your arm** — usually the forearm or hand. The site is flushed with saline before the iron is started. 4. Your blood pressure, pulse, and temperature are checked. **The iron infusion begins** and runs over approximately 15–20 minutes in 250ml of normal saline. A nurse will check on you throughout. 5. Once the infusion is complete, the line is flushed again with saline. **You then rest for 30 minutes** in the clinic while we monitor you for any delayed reaction — this observation period is mandatory and cannot be skipped. 6. Observations are rechecked. Your clinician confirms you are well, the cannula is removed, and **you are free to go home**. ![Eating Healthy – Iron Infusion](https://outsidetheboxcare.com.au/files/images/Treated-Images/_2880x2880_crop_center-center_70_none_ffffff/15283/Eating-Healthy.webp) #### **Please tell us immediately if:** at any point during or after the infusion you feel chest tightness, difficulty breathing, itching, flushing, nausea, dizziness, or any pain or swelling at the cannula site. These are rare — but we need to know right away. ## Side effects you need to know about What to look out for in the days after. Most people tolerate iron infusions very well. These are the side effects worth knowing about: ![Icon Sitting For Long periods](https://outsidetheboxcare.com.au/files/images/Icons/Icons-Red/Icon-Sitting-For-Long-periods.svg) #### **Bone and muscle aches (2–3 days after)** Some people experience deep bone aches or general muscle soreness 2–3 days after their infusion. This is temporary and settles on its own. Paracetamol and ibuprofen help. It is not a sign that anything has gone wrong. ![Icon Sleeping](https://outsidetheboxcare.com.au/files/images/Icons/Icons-Red/Icon-Sleeping.svg) #### **Low phosphate and fatigue (days to weeks after)** Ferinject can temporarily lower phosphate levels, which may cause fatigue or weakness. This is why the high phosphate diet before and after is so important. Your doctor may check your phosphate levels at your follow-up blood test. ![Icon Dizziness](https://outsidetheboxcare.com.au/files/images/Icons/Icons-Red/Icon-Dizziness.svg) #### **Headache or lightheadedness** Usually mild and settles within a day or two. Stay hydrated and rest if needed. --- ![Icon Anemia](https://outsidetheboxcare.com.au/files/images/Icons/Icons-Red/Icon-Anemia.svg) #### **Iron staining at the infusion site** If iron leaks from the vein at the cannula site, it can cause a permanent brownish skin stain. This is rare but worth knowing — we take care to avoid it, but please tell us immediately if you feel any burning or pain at the site during the infusion. ![Icon Vomitting](https://outsidetheboxcare.com.au/files/images/Icons/Icons-Red/Icon-Vomitting.svg) #### **Allergic or hypersensitivity reaction** Serious allergic reactions are rare (less than 2%). We monitor you closely for the first five minutes of the infusion and for 30 minutes afterwards for this reason. Our clinic is equipped and trained to manage any reaction. **Go to emergency immediately** if after leaving the clinic you experience difficulty breathing, swelling of the face, lips or throat, severe rash, chest pain, or feel you are having a serious allergic reaction. **Call 000.** ## After your infusion Recovery and follow-up. Most people feel well after their infusion and can return to normal activities. Some people feel noticeably better within days — more energy, clearer thinking, and less breathlessness. For others, the improvement builds gradually over 4–8 weeks as your body uses the iron to replenish stores and restore haemoglobin levels. 1. **Continue your high phosphate diet** for 1–2 weeks after the infusion 2. You do not need to take oral iron after your infusion — it is not necessary and may reduce the effectiveness of the intravenous iron 3. **Follow-up blood tests** — your doctor will arrange repeat blood tests (haemoglobin, iron studies, and possibly phosphate) approximately 4–6 weeks after your infusion to check your response 4. Call us if you develop bone aches, persistent fatigue, or any ongoing concerns 5. Some people require a second infusion or ongoing infusions — your doctor will discuss this based on your follow-up results and the underlying cause of your iron deficiency ![Hands on torso treated 1](https://outsidetheboxcare.com.au/files/images/Treated-Images/_2880x2880_crop_center-center_70_none_ffffff/11086/hands-on-torso_treated-1.webp) ### Make an enquiry Fill in the form below and our care team will be in touch to confirm your iron infusion appointment.
