Abstract:BACKGROUND: A sublingual misoprostol-alone regimen was used in 50 women requesting medical abortion at up to 12 weeks gestation. The efficacy and acceptability of this regimen were studied. METHODS: The women were given 600 μg misoprostol sublingually every 3 h for a maximum of 5 doses. RESULTS: The overall complete abortion rate was 86% (95% confidence interval: 74–93). The mean number of doses of misoprostol required was 4.1 ± 1.1. There was no significant change in haemoglobin concentration and the median duration of vaginal bleeding was 15 days (range: 7–56). Diarrhoea, fever and chills were the most common side-effects. The acceptability of this regimen of misoprostol was good: 97.7% of the women who had a complete abortion would choose this method again and 88.4% would recommend it to others. They preferred sublingual misoprostol as it is convenient to take, avoids the painful vaginal administration and gives more privacy during the abortion process. CONCLUSION: This regimen of sublingual misoprostol is an effective and acceptable method of medical abortion. Randomized controlled trials are required to compare the efficacy of various misoprostol-alone regimens of medical abortion. Pharmacokinetic studies and clinical trials are needed to find out the most appropriate dose, dosing interval and route of administration of misoprostol.
