Advice on emergency contraception

摘要

Emergency contraception is defined as the measures taken after an act of unprotected (or inadequately protected) sexual intercourse (UPSI) to avoid pregnancy. In the UK, two methods are licensed for use: emergency hormonal contraception (EHC) and the insertion of a copper-bearing intrauterine contraceptive device (IUCD).The latter is less well known and not so commonly requested or offered. However, it is more effective than EHC and has the advantage of providing ongoing contraception. It is also licensed for use beyond the 72-hour window that applies to EHC.
