Contraceptive patch

The contraceptive patch is a small sticky patch that releases hormones into your body through your skin to prevent pregnancy. In the UK, the patch's brand name is Evra. When used correctly, the patch is more than 99% effective at preventing pregnancy.

Each patch lasts for a week. You change the patch every week for three weeks, then have a week off without a patch.

The patch releases a daily dose of hormones through the skin into the bloodstream to prevent pregnancy.

It contains the same hormones as the combined pill – oestrogen and progestogen – and works in the same way by preventing the release of an egg each month (ovulation).

If you have no symptoms and want a straightforward test you can:

  • either order a smart kit online for home delivery
  • or attend one of our clinics where you can collect a smart kit without needing to wait and see a clinician.

This is a quick, easy and confidential way to screen for chlamydia, gonorrhoea, HIV and syphilis.
