Background: In most countries in which abortion is legal, medical abortions are induced with mifepristone and misoprostol. Since mifepristone is expensive and unavailable in many countries, it is important to find other regimens. Methotrexate, which is used with misoprostol in Canada, is also difficult to obtain in many countries. Misoprostol is inexpensive and available in almost all countries. A report from Nigeria found that 98% of 100 women aborted within 24 hours of using misoprostol given both sublingually and vaginally.
