The contraceptive patch, also called Evra, is a small beige patch applied to the skin like a sticky plaster, which protects against pregnancy.
The patch releases two hormones, oestrogen and progestogen into the bloodstream through the skin.
It stops the ovaries from releasing an egg for fertilisation every month. It also thickens the mucus around the cervix, which makes it difficult for sperm to get into the womb.
The patch is 99% effective when used correctly.
