Contraceptive patch

How effective is it.

The Contraceptive Patch is over 99% effective if used according to instructions. Less than one woman in 100 will get pregnant in a year.

How does it work.

A small patch is stuck on the skin and releases two hormones, estrogen and
progestogen. This stops ovulation, thickens cervical mucus to prevent sperm
reaching an egg, and thins the lining of the uterus (womb) to prevent a fertilised egg
implanting.

What are the advantages.

You don’t have to think about it every day.
It is not affected if you vomit or have diarrhoea.
The Contraceptive Patch can make periods regular, lighter and less painful.
It may protect against cancer of the ovary, colon and uterus. When you stop using the patch your fertility will return to normal.

What are the disadvantages.

The Contraceptive Patch is not suitable for very overweight women or smokers over 35 years.
There is very low risk of serious side-effects such as blood clots, breast and cervical cancer.
There can be temporary side-effects such as headaches, nausea, mood changes and breast tenderness.
Possible skin reactios may be seen.

Anything else I should know.

A new Contraceptive Patch has to be used each week for three weeks out of four.
Some medicines can make it less effective.
Breakthrough bleeding and spotting is common in the first few months.
