Iron showdown: IV vs pills for anemia in pregnancy
NCT ID NCT04278651
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether giving iron through a vein (IV) early in the second trimester works better than iron pills for treating anemia in pregnancy. About 80 pregnant women with mild iron deficiency will be randomly assigned to one of the two treatments. The goal is to see which approach improves blood counts, reduces side effects, and boosts quality of life.
