Abstract

Background

Misoprostol is widely used for induction of labor at term because it is inexpensive, stable at room temperature, and effective for cervical ripening.

Objectives

To assess dose patterns, induction-to-delivery interval, delivery outcomes, and maternal and neonatal complications among women induced with misoprostol at term.

Methods

This hospital-based observational study included 100 term pregnant women induced with misoprostol at a tertiary care teaching hospital from April 2025 to November 2025. Baseline characteristics, indication for induction, number of doses, total dose, time to delivery, mode of delivery, and complications were recorded and analyzed descriptively.

Results

Most women were 21-30 years old, and 56% were primigravida. Postdated pregnancy was the commonest indication. Two doses were most frequently required, and the mean total dose was 63.5 ± 22.4 µg. The mean induction-to-delivery interval was 11.6 ± 4.8 hours and was longer in primigravida than multigravida women. Normal vaginal delivery occurred in 72%, instrumental vaginal delivery in 8%, and cesarean delivery in 20%, yielding an overall vaginal delivery rate of 80%. Uterine tachysystole occurred in 7%, hyperstimulation in 3%, postpartum hemorrhage in 4%, and NICU admission in 8%.

Conclusion

Misoprostol induction at term showed good effectiveness with an acceptable safety profile in routine tertiary care practice. Most women achieved vaginal delivery within a clinically reasonable interval, and serious maternal or neonatal complications were uncommon.

Recommendations
Misoprostol may be considered a safe and effective agent for induction of labor at term when used with appropriate dosing and monitoring. Further multicentric studies with larger sample sizes are recommended to establish optimal protocols and strengthen evidence-based clinical guidelines.
