What you need to know about the patch
The contraceptive patch is a 5cm by 5cm sticky beige patch. It looks a bit like a plaster you use to cover a cut on your skin. It contains synthetic versions of the body’s reproductive hormones, oestrogen and progesterone.
The patch releases these hormones at a controlled rate and they get absorbed into your bloodstream through your skin.

Likelihood of getting pregnant over 1 year
The patch is highly effective at preventing pregnancy if you remember to change it on time. Used perfectly, the patch is over 99% effective.
But none of us is perfect and it's more usual for people to be late with a patch or not follow the instructions exactly. So with more typical use, it's 91% effective. This means typically 9 in 100 people using the patch will get pregnant in one year.

You can choose when you bleed
You can use the patch in 3 different ways. You can choose to have no bleeding at all, a regular monthly bleed or a bleed every 3 months. When you do bleed, it will be lighter, shorter and less painful than your usual period.
Many women find they have fewer problems with acne when they use the contraceptive patch.
It can reduce the risk of some cancers but increase others
The contraceptive patch uses very similar hormones to the combined pill. This means that they have the same effects, including reducing the risks of cancers of the ovary, uterus and colon but slightly increasing the risk of breast cancer.
