This undated file photo received 26 January 2004, shows the US contraceptive patch Ortho Evra, the first once-a-week birth control patch. The patch has been approved for use in Europe. In clinical trials the patch, manufactured by Janssen-Cilag, was found to be 99% effective — a similar rate to the Pill. The thin patch can be worn on one of four places on a woman’s skin and will stay on during swimming exercise or bathing. AFP PHOTO/HO ORG XMIT: DCA96
