Evra contains two hormones that are similar to the hormones oestrogen and progesterone that are produced by the body. Evra is used to prevent women from becoming pregnant. It works by preventing the release of eggs from the ovary. Evra also changes the lining of the uterus which makes it difficult for an egg to develop and it increases the thickness of vaginal fluid which can stop sperm from reaching an egg.
Evra may increase the chances of developing blood clots or cancers such as cervical or breast cancer. However, it may provide some protection against ovarian and endometrial cancer. You and your prescriber will need to weigh up the benefits and risks of using Evra before you start to use it.
Hormonal contraceptives will only prevent a pregnancy if they are used regularly. Evra needs to be applied once a week. If you want immediate contraceptive cover then start to use Evra on the first day of your menstrual period. If you do not start using Evra on the first day of your menstrual period you will need to take extra contraceptive precautions for at least seven days until Evra starts to work. For more information about starting Evra and if you need to take extra contraceptive precautions ask your prescriber, family planning nurse or read the patient information leaflet that comes with your medicine.
Once you have started using Evra, you should apply a new patch every seven days for three weeks. After this you should not use a patch for the fourth week. Start using a new patch of Evra immediately after the seven-day patch-free break. This break must not be longer than seven days. During this break you will usually have a withdrawal bleed. If you do not have a withdrawal bleed during the patch-free break and you have used all your patches properly, you are very unlikely to be pregnant. However, if you miss a withdrawal bleed and you have not used your patches correctly or if you miss two withdrawal bleeds in a row you should immediately contact your prescriber or family planning nurse. This is because there is a possibility that you could be pregnant and you must not use Evra during pregnancy.
In certain situations the effectiveness of Evra may be reduced and you will need to take extra contraceptive precautions. These situations include: not applying a new patch on the correct day; the patch either partly or completely falling off; or if you are taking other medicines that interact with Evra. If any of these situations occur you may need to change your routine. For more information on when to take additional contraceptive precautions ask your prescriber, family planning nurse or read the patient information leaflet that comes with your medicine.
Evra does not protect against HIV infections or other sexually transmitted diseases.
