MYTH: Iron infusions are only for people who are seriously ill.
REALITY: An infusion is often the most appropriate first-line treatment, not a last resort.
Here’s when an infusion makes more sense than oral supplements:
→ Ferritin is very low and needs to be corrected quickly
→ Oral iron is causing significant GI side effects (constipation, nausea, cramping)
→ The patient has a GI condition affecting absorption - Crohn’s, coeliac, IBS
→ Pregnancy or postpartum demands require rapid iron correction
→ The patient has tried oral supplements without adequate response
→ An athlete needs stores corrected within a specific training window
Oral iron is appropriate for many patients. But it absorbs slowly, is often poorly tolerated, and can take months to restore depleted stores.
An intravenous infusion delivers iron directly into the bloodstream - bypassing the gut entirely. Most patients see meaningful improvement within 2-4 weeks.
It’s not dramatic. It’s just the right tool for the right patient.
