Abstract

Research on medical abortion has been conducted in Hong Kong since the 1990s. It was not until 2011 that the first-trimester medical abortion service was launched. Mifepristone was registered in Hong Kong in April 2014 and all institutions that are listed in the Gazette as a provider for legal abortion can purchase mifepristone from the local provider. This article aimed to share our 3-year experience of this service with the local medical community. Our current protocol is safe and effective, and advocates 200-mg mifepristone and 400-µg sublingual misoprostol 24 to 48 hours later, followed by a second dose of 400-µg sublingual misoprostol 4 hours later if the patient does not respond. The complete abortion rate is 97.0% and ongoing pregnancy rate is 0.4%. Some minor side-effects have been reported and include diarrhoea, fever, abdominal pain, and allergy. There have been no serious adverse events such as heavy bleeding requiring transfusion, anaphylactic reaction, septicaemia, or death.
