The contraceptive patch (transdermal patch) is a type of contraception that delivers hormones into your body through your skin which stop you getting pregnant.
Unlike barrier methods of contraception, such as condoms, the contraceptive patch does not protect against sexually transmitted infections (STIs).
The patch needs to replaced each week, with a patch-free week every fourth week. This is when you have a withdrawal bleed, like a period.

How the patch works
The contraceptive patch is a small, thin, beige patch about 5cm by 5cm in size (much like a nicotine patch). It works by releasing daily doses of the female sex hormones oestrogen and progestogen into your bloodstream through your skin.
The patch works in the same way as the combined oral contraceptive pill by:
- stopping your ovaries releasing an egg each month (ovulation)
- thickening the mucus in your cervix (entrance to the womb) making it difficult for sperm reach your womb
- thinning the lining of your womb so it is harder for an egg to attach to the womb
Where can I get it?
Most types of contraception are available free in the UK. Places where you can get contraception include:
- most GP surgeries - talk to your GP or practice nurse
- community contraceptive clinics
- some genitourinary medicine (GUM) clinics
- sexual health clinics – they also offer contraceptive and STI testing services
- some young people’s services (call 0800 567123 for more information)
Contraception services are free and confidential, including for people under the age of 16.
Find your nearest sexual health clinic by searching by postcode or town.
Not everyone can use the patch, so it is important to see a doctor or nurse to check that it is suitable for you.

How effective is the contraceptive patch?
If used properly, the contraceptive patch is over 99% effective in preventing pregnancy.
However, research has shown that the patch may be less effective for women who weigh 90kg (14 stone) or over.
The contraceptive patch is very easy to use and does not interrupt sex. Unlike the pill, you do not have to think about it every day. You only have to remember to change the patch once a week. Read more about the advantages of the contraceptive patch.
There are also disadvantages of the contraceptive patch to consider. The contraceptive patch may:
- be visible
- cause skin irritation, itching and soreness
- cause mild, temporary side effects such as headaches, nausea (sickness), breast tenderness and mood changes
- cause bleeding between periods and spotting (very light, irregular bleeding) - this is common in the first few cycles of using the patch
- be less effective when using some medicines
Are there any risks?
There is a very small risk of developing a blood clot when using a hormonal contraceptive. If you have had a blood clot before, do not use the patch.
Research also suggests that hormonal contraception slightly increases the risk of developing breast cancer and cervical cancer. Further research is needed to provide more definite evidence.
However, for most women the benefits of the patch far outweigh the risks.
