What to expect from your Monoferric infusion
You have been referred for an intravenous (IV) iron infusion called Monoferric (ferric derisomaltose). The infusion itself is performed by a specialty infusion center, not at our clinic. This page walks you through the coordination process, what happens at the visit, and what to watch for afterward.
Why you are getting this infusion
Your blood tests show a low ferritin, which means your body’s iron stores are low. Iron is the building block your body uses to make hemoglobin, the part of red blood cells that carries oxygen. When iron runs low, you can develop iron deficiency, and if it drops further, iron deficiency anemia.
IV iron is usually recommended when:
- Iron tablets have not worked well enough, or
- Iron tablets cause side effects you cannot tolerate (such as stomach upset or constipation), or
- Your iron stores need to be refilled more quickly than tablets allow.
Monoferric delivers a large amount of iron in a single infusion, refilling your iron stores in one visit rather than over months of pills.
How this gets scheduled
Your infusion is performed by Reliant Specialty Infusion, which has Louisiana locations in Alexandria, Baton Rouge, Lafayette, Lake Charles, and Metairie. We coordinate with them on your behalf. Here is how the process works.
At the infusion center
Once Reliant has scheduled you, here is what to expect at the visit itself.
Reliant’s care team stays nearby throughout the infusion and checks on you.
What it helps — and when you may feel better
Restoring your iron can improve symptoms that come from low iron and anemia:
- Fatigue and low energy
- Shortness of breath with activity
- Reduced exercise ability
- Brain fog and poor concentration
- Headaches, dizziness, or lightheadedness
Everyone is different. If your iron loss is ongoing (for example, from heavy periods or bleeding), we may need to recheck your levels and repeat treatment in the future.
Possible side effects
Most people tolerate the infusion well. Possible effects are grouped by how often they occur.
- Nausea
- Rash or itching
- Headache or dizziness
- Flushing
- Muscle or joint aches, back pain
- Tiredness or feeling unwell for a day or so
- A reaction during or shortly after the infusion — flushing, chest or back tightness, warmth — that usually settles when the infusion is slowed or paused
- Signs of a more serious allergic reaction: rash or hives, itching, swelling of the face, lips, or tongue, trouble breathing, wheezing, chest tightness, feeling faint, or a fast heartbeat
Serious allergic reactions are rare but can be life-threatening. This is why you are monitored during and after the infusion.
In clinical trials, serious or severe allergic reactions occurred in about 0.3% of people (roughly 3 in every 1,000). Large real-world studies have reported similar rates of about 0.4%, with anaphylaxis (the most severe type) in fewer than 1 in 1,000.
IV iron can sometimes lower phosphate levels in the blood. This is less common with Monoferric than with some other IV irons, but we may check it if you have symptoms or need repeated infusions.
Who should not receive it
- Anyone who has had a serious allergic reaction to Monoferric before
- People who already have too much iron stored in their body (iron overload)
Tell your care team if you have ever had a reaction to any IV iron product, or if you have any allergies.
After your infusion — when to seek help
Call your doctor or seek urgent care if, in the hours or days after your infusion, you develop:
- Trouble breathing, wheezing, or chest tightness
- Swelling of the face, lips, or tongue
- A widespread rash, hives, or severe itching
- Feeling faint, or a racing heartbeat
For mild aches, low-grade symptoms, or a spot of skin staining at the IV site, let us know at your next contact.
Questions to ask your care team
- Do I need a follow-up blood test, and when?
- Might I need another infusion in the future?
- Is the cause of my low iron being looked into (for example, bleeding or diet)?
What to remember
- The infusion is performed by Reliant Specialty Infusion, not at our clinic. Your first step is uploading your insurance and demographics so we can send the order.
- Monoferric refills your iron stores in one visit, instead of months of pills.
- Plan on being at Reliant for about an hour — 20+ minutes of infusion, 30+ minutes of monitoring afterward.
- Fatigue often improves within the first 1–2 weeks. Your blood count catches up over 4–8 weeks.
- Serious reactions are rare — more than 99% of people don’t have one — but you are monitored so staff can respond if one occurs.
