Contraceptive Patch

The contraceptive patch is a small, thin, adhesive patch that releases hormones (oestrogen and progestogen) into your bloodstream to prevent pregnancy. It is a convenient alternative to the pill for people who prefer weekly contraception instead of daily pills.

How does the patch work?

The patch prevents pregnancy by:

  • Stopping ovulation (preventing an egg from being released)
  • Thickening cervical mucus to block sperm
  • Thinning the lining of the womb to reduce the chance of implantation

How effective is it?

  • Over 99% effective with perfect use
  • Around 91% effective with typical use (if patches are missed or replaced late)

How do I use the patch?

  • Apply one patch to clean, dry skin on your:
    *Upper arm
    *Buttock
    *Stomach (avoiding the breasts)
  • Wear the patch for 7 days, then replace it with a new one on the same day each week
  • Three patches are used in a row, followed by a patch-free week, during which you will usually have your period.

Your GP or nurse will explain the correct placement and schedule.

When does it start working?

  • If you apply the patch on day 1 of your period → protected immediately
  • If applied at any other time → use additional contraception (e.g., condoms) for 7 days
