IV iron may beat pills for anemia in late pregnancy
NCT ID NCT04253626
First seen Jun 30, 2026 · Last updated Jul 01, 2026 · Updated 1 time
Summary
This study tests whether a single intravenous dose of ferumoxytol raises hemoglobin more effectively than daily oral ferrous sulfate in pregnant women with iron deficiency anemia. Participants are between 24 and 34 weeks pregnant with a single baby. The trial measures hemoglobin changes, side effects, and whether fewer women need blood transfusions after delivery.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
ferumoxytol (intravenous) and ferrous sulfate (oral)
What this could lead to
If IV iron works better, it could offer a faster, more effective treatment for anemia in late pregnancy, reducing the need for blood transfusions.
What could go wrong
This is a single-center trial with 83 participants, so results may not apply broadly. IV iron carries a small risk of allergic reactions.
