Aims and Objectives To compare the efficacy, safety, and rate of response of intravenous iron sucrose and intramuscular iron sorbitol therapy for anemia during pregnancy. Material and Methods 100 antenatal cases of gestational age 14-32 weeks were included in this prospective study. Cases were randomly divided into two groups. Group A, having 50 cases received intravenous iron sucrose, and 50 cases in Group B received intramuscular iron sorbitol. Response to therapy in both groups was studied and compared. Results The mean pretherapy hemoglobin in group A was 6.49 gm/dl and in group B was 6.48 gm/dl. The rise in hemoglobin after 4 weeks of starting therapy was 3.52 gm/dl in group A and 2.33 gm/dl in group B. The difference was statistically significant (P \ 0.01). The mean time taken to achieve target hemoglobin (C11 gm/dl) was 6.37 weeks in group A and 9.04 weeks in group B. In group A, 8 % (four) cases had grade I adverse effects. In group B, 24 % (12) cases had grade I adverse effects. The difference was statistically significant (P = 0.027). In both the groups, no case discontinued the therapy. Conclusion Intravenous iron sucrose is safe, convenient, more effective, and faster acting therapy than intramuscular iron sorbitol therapy for treating moderate to severe anemia during pregnancy.
