Evra patches are contraceptive patches you apply to your skin once a week. They keep you up to 99% protected from pregnancy and you don’t need to worry about taking a pill every day.

Evra patches contain two hormones, progesterone and oestrogen, just like the contraceptive pill. They work by preventing an egg from being released from the ovaries (ovulation), thickening the cervical mucus, making it difficult for the sperm to get to an egg and thinning the lining of the womb, making it harder for a fertilised egg to implant itself. All you have to do to get started is apply your first patch on the first day of your period, and then remember to change it once a week.
