IV Iron Infusions: Understanding the Five Most Common Options
IV iron therapy · Safety · Home infusion
Intravenous (IV) iron is a proven way to treat iron deficiency when pills are not enough or not tolerated. In the United States, clinicians typically choose among five formulations, each with its own mix of dosing, safety, convenience, and cost. Because studies show similar efficacy when total doses match, there is no single "gold standard"—the goal is to pick the option that balances safety and practicality for the setting.
Below is a clean comparison of the five most common IV iron products, how they are used, their pros and cons, and typical cash-pay price ranges. We also explain why iron sucrose (Venofer) is usually the most appropriate choice for home infusions.

The Five Common IV Iron Formulations
All five options below can effectively replenish iron stores. The main differences are dose per visit, number of visits required, risk profile, and price.
Iron Sucrose (Venofer)
One of the most widely used options across outpatient infusion centers, dialysis, obstetrics, and general medical practices.
Pros
- Excellent safety record and low rate of severe reactions
- Well tolerated across diverse patient populations
- Predictable improvements in iron and hemoglobin levels
- Flexible dosing allows gradual repletion
Cons
- Requires multiple infusions (commonly 3-5) to deliver the full dose
- Not ideal for those seeking a single high-dose infusion
Sodium Ferric Gluconate (Ferrlecit)
A long-standing formulation commonly used in dialysis care and other chronic medical settings.
Pros
- Long-established safety record
- Well tolerated
- Effective for gradual iron repletion
Cons
- Smaller dose per infusion (125 mg), requiring multiple visits
- Less commonly used outside nephrology contexts
Low-Molecular-Weight Iron Dextran (INFeD)
Unique because it can be given as a total-dose infusion, replenishing the entire iron deficit in one visit.
Pros
- Can deliver up to 1,000 mg or more in one session
- Effective for rapid repletion
Cons
- Higher risk of severe hypersensitivity reactions compared with iron sucrose and ferric gluconate
- Historically required a test dose
- Not preferred in home infusion due to its risk profile
Ferumoxytol (Feraheme)
A newer formulation designed for convenience and rapid dosing, often administered as two 510 mg infusions.
Pros
- Very convenient dosing
- Rapid improvements in iron and hemoglobin levels
- Useful when rapid correction is clinically important
Cons
- Higher risk of hypersensitivity and anaphylaxis compared with iron sucrose and ferric gluconate
- FDA Black Box Warning
- Very high retail cost, making it impractical for cash-pay or home infusion
Ferric Carboxymaltose (Injectafer / Ferinject)
A high-dose option often given as two 750 mg infusions.
Pros
- Efficient repletion in 1-2 visits
- Well-studied internationally
- Rapid hemoglobin improvement
Cons
- Higher rates of hypophosphatemia than iron sucrose
- Very expensive for self-pay patients
- Not ideal for home infusion due to risk and cost
What the Research Shows: Similar Efficacy Across Formulations
- Modern IV iron formulations replenish iron stores effectively when equivalent doses are used.[1][2]
- Hemoglobin increases similarly across products in head-to-head trials.[1][3]
- Serious adverse events are rare overall, but risk levels vary by formulation.[4][5]
- Because efficacy is similar, clinicians focus on safety, cost, convenience, and infusion setting when selecting a product.[6]
This is why no single IV iron product is "the best" in every setting. The choice hinges on balancing safety and logistics with patient goals and the care environment.
Why Venofer Is the Most Practical Choice for Home Infusion
Home infusion prioritizes:
- Low and predictable risk
- Excellent tolerability
- Cost-effectiveness
- Clear dosing protocols
- Smooth scheduling for multi-session treatments
- Safety within a non-hospital environment
Iron sucrose (Venofer) stands out because:
- Safety first: One of the lowest rates of serious infusion reactions among IV iron products.[4]
- Cost matters: Retail pricing around $300-$600 per infusion makes it far more accessible than options that cost thousands per visit.
- Equivalent outcomes: Studies show Venofer replenishes iron and improves hemoglobin as effectively as newer, more expensive formulations.[1][2][3]
- Ideal for home infusion: Even with trained nurses, choosing a lower-risk formulation minimizes the likelihood of complications in a home setting.
- Aligned with best practices: Expert reviews emphasize selecting formulations based on safety profile and cost-effectiveness, not theoretical efficacy differences.[6]
Because of this combination of safety, effectiveness, and affordability, Venofer remains the most appropriate and responsible first-line choice for home-based iron infusion therapy.

We review your labs, timing needs, and risk factors to coordinate the safest path to replenishing iron.
Conclusion
All five IV iron formulations can work when dosed appropriately, but they differ meaningfully in risk, price, and logistics. For home infusion, iron sucrose (Venofer) offers the best balance of safety, predictability, and affordability while achieving the same clinical outcomes as higher-priced alternatives.
If your labs confirm iron deficiency or iron-deficiency anemia, partnering with a clinician who understands both the pharmacology and the practicalities of home infusion is the safest way to replenish your levels.
