A randomized controlled trial examining the addition of folic acid to iron supplementation in the treatment of postpartum anemia

Abstract Objective To evaluate the efficacy of adding folic acid to oral iron supplementation in postpartum women with anemia. Methods A randomized controlled trial was conducted in the Netherlands between April 8, 2008, and August 31, 2010. A total of 112 postpartum women with anemia (hemoglobin Results No between-group differences were observed in hemoglobin and health status after treatment, and no differences were found in fatigue scores. Approximately 75% of all women reported having at least one symptom resulting from ferrous fumarate use. Constipation caused by ferrous fumarate was significantly associated with non-compliance ( P  = 0.014). Conclusion The addition of folic acid to iron supplementation is not beneficial in women with postpartum anemia, as it has no effect on hematologic or health status parameters.
