DES also used as an emergency contraceptive in The United Kingdom, 1973
Oestrogens as postcoital contraception have been prescribed for 282 women at the Brook Advisory Centre (Avon) since January 1973.
A daily dose of 50 mg diethylstilboestrol for 5 days started within 72 hr of unprotected intercourse was used from January 1973. This was changed to 5 mg ethinyl oestradiol in May 1974.
There were no pregnancies nor any serious side effects. Follow-up showed that most women had their next period at the expected time.
