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
