Objective:
To evaluate and compare the effectiveness and side effects of two regimens of oral misoprostol, single dose (600 microg) and repeated dose (1200 microg), in the treatment of incomplete abortion.
Methods:
A prospective randomized controlled trial was conducted. One-hundred women who had incomplete abortion (gestational age < 20 weeks) and consented to randomization by computer-generated randomization model prior to treatment. A single oral 600-microg dose or repeated oral dose after 4 h (total 1200 microg) was given to the randomized women.
Results:
The overall incidence of complete abortion was 86.9%. This incidence was not statistically different between the single-dose and repeated-dose groups (81.6% vs. 92%, p > 0.05). However, there was a significantly decreased incidence of diarrhea (18.4% vs. 40%, p < 0.05) with the use of single-dose treatment. Overall rate of acceptability and tolerable side effects were 88.9% and 97.9%, respectively. These rates were similar in both groups (87.8% vs. 90% and 98% vs. 98%, p > 0.05).
Conclusions:
Oral misoprostol may be a practical alternative in the management of incomplete abortion. Oral misoprostol is acceptable and tolerable to women. Single-dose regimen is as effective as repeated-dose regimen, with a reduction in the incidence of diarrhea.
