The combined contraceptive patch is a small soft plaster patch that you stick on your skin. It contains two hormones, progestogen and oestrogen, similar to the hormones in your body.
The two hormones primarily prevent an egg from being released each month. They also make it difficult for sperm to get to an egg and thin the uterus (womb) lining which makes it difficult for a fertilised egg to implant there.
The patch is left on the skin continuously night and day for one week and then a new patch is applied to a different area.
How good is the patch at preventing a pregnancy?
- The patch works well at preventing pregnancy. However, its ability to stop a pregnancy largely depends on a person using it properly.
- With typical use up to 7 out of 100 users will become pregnant
- If you think you will not be able to remember to replace the patch once a week, it may not be the right method for you.
What are the advantages of the patch?
- It can make your periods regular, lighter, and less painful
- It gives you the choice not to have a monthly bleed or control when you have a bleed

This means using a male or female condom in addition to the contraceptive method of your choice to prevent pregnancy.
