Objective To compare the efficacy and adverse effects of sublingual misoprostol, intravenous oxytocin, and intravenous methylergometrine in active management of the third stage of labor (AMTSL). Methods A double‐blind randomized trial of 300 women with a healthy singleton pregnancy allocated into 4 groups to receive either: 400 µg or 600 µg of sublingual misoprostol, 5 IU of intravenous oxytocin, or 200 µg of intravenous methylergometrine. The primary outcome measure was blood loss in the third and fourth stage of labor; secondary measures were duration of the third stage of labor, changes in hemoglobin levels, and adverse effects. Results Patients who received 600 µg of misoprostol had the lowest blood loss (96.05 ± 21.1 mL), followed by 400 µg of misoprostol (126.24 ± 49.3 mL), oxytocin (154.7 ± 45.7 mL), and methylergometrine (223.4 ± 73.7 mL) ( P < 0.01). Shortest mean duration of the third stage of labor (5.74 minutes) was with 600 µg of misoprostol, while methylergometrine had the longest (6.83 minutes) ( P < 0.05). Pyrexia was observed in the misoprostol groups, and raised blood pressure in the methylergometrine group ( P < 0.001). The 24‐hour postpartum hemoglobin level was similar among the groups ( P > 0.05). Conclusion Administration of 600 µg of sublingual misoprostol was more effective than 400 µg of misoprostol, intravenous oxytocin, and intravenous methylergometrine for AMTSL.
