The effectiveness of intravenous ferric carboxymaltose (FCM) in quickly increasing normal hemoglobin concentration and replenishing body iron reserves up to 6-12 wk is known; however, its long-term effectiveness is unknown. In this study conducted in northern India during August 2018 to February 2019, 100 postpartum women within 48 h of delivery with a hemoglobin concentration between 5.0 and 9.9 g/dL were included. A single dose of intravenous FCM was administered. The hemoglobin and serum ferritin concentrations were measured at baseline and at 6 mo. Out of 100 women recruited, 57 (57%) returned for the follow-up visit at 6 mo. The mean (± SD) hemoglobin and serum ferritin concentrations at baseline were 8.6 ± 1.1 g/dL and 15.8 ± 17.2 ng/mL, respectively, and at 6 months were 12.5 ± 1.2 g/dL and 72.0 ± 52.0 ng/mL, respectively. The mean increase in hemoglobin concentration was 3.9 (95% CI: 3.5, 4.3) g/dL (P < 0.001) and for serum ferritin was 53.8 (95% CI: 41.8, 65.8) ng/mL (P < 0.001). The study was registered prospectively in the Clinical Trials Registry-India (CTRI) as CTRI/2018/06/014332.
