Abstract

Intramuscular methotrexate followed by vaginal misoprostol has been shown to be effective for abortion at ≤49 days gestation. Oral dosing of the methotrexate may offer advantages over parenteral dosing. This pilot study was performed to evaluate if oral methotrexate would be effective when combined with vaginal misoprostol to effect abortion at ≤49 days gestation. Twenty pregnant women were randomized to receive methotrexate 25 mg or 50 mg followed 7 days later by misoprostol 800 μg vaginally. The misoprostol dose was repeated the next day if the abortion did not occur. Complete abortion occurred in all subjects in both groups within 20 days after the methotrexate. However, women in the 50 mg group passed the pregnancy within 24 hours of the first or second dose of methotrexate more often than women in the 25 mg group (80% vs. 50%, p = 0.35). Vaginal bleeding lasted 12.1 ± 3.1 days and 9.4 ± 4.5 days in immediate success and delayed success patients, respectively. Oral methotrexate may be an effective alternative to surgical abortion.
