Abstract

Background: A randomized controlled trial comparing sublingual with vaginal administration of misoprostol for medical management of silent miscarriages.

Methods: Eighty women who had silent miscarriages (<13 weeks) were randomized to receive 600 micro g of misoprostol every 3 h for a maximum of three doses either sublingually or vaginally.

Results: The success rates of medical management were the same in both groups (87.5%; 95% CI: 74-95%). There were no serious complications. The incidence of diarrhoea was higher in the sublingual (70%) than the vaginal route (27.5%) (P < 0.005). Other side effects were similar in each group, although fatigue was experienced by more women in the sublingual group than in the vaginal group (65 versus 40%: P = 0.043). The overall acceptability of medical management was good. Most women would choose the medical method if they were allowed to choose again and would recommend the method to others.

Conclusion: The current regimen of misoprostol is useful for the management of silent miscarriage in terms of complete miscarriage rate and patient acceptability. Sublingual misoprostol may offer an alternative for women who do not like repeated vaginal administration of the drug.
