The controversial "morning-after pill" was made available free to girls aged under 16 in a pilot programme introduced in south Wales today, a project adviser said.
The health authority in the town of Bridgend, which has one of Europe's highest teenage pregnancy rates, said 10 pharmacies would make the pill available confidentially and without prescription.
Dr Rosemary Fox, one of the project's medical advisers, said "similar schemes have been operating successfully in Manchester and the London boroughs of Lambeth, Lewisham and Southwark, where levels of teenage pregnancy are also worrying."
Britain has one of the highest abortion rates in Europe.
The morning-after pill induces miscarriage by blocking a hormone needed to maintain pregnancy, and is the only nonsurgical alternative for women who wish to terminate a pregnancy at up to seven weeks.
The pill went on sale over-the-counter in Britain this month to women older than 16 sparking protests by family groups, anti-abortion camapaigners and some religious leaders.
