Evra patches are a combined hormonal contraceptive for use by women to prevent pregnancy
Evra patches are worn on the skin and need replacing once a week
When used correctly, Evra patches are one of the most reliable methods of contraception
Evra contains two types of sex hormones, a progestogen called norelgestromin and an oestrogen called ethinyl estradiol and is called a ‘combined hormonal contraceptive’ and is used to prevent pregnancy.
The patches work in the same way as the oral contraceptive pill. They stop the ovaries from releasing an egg, they change the lining of the womb and thicken vaginal fluids so that sperm cannot enter the womb.
Weeks 1, 2 & 3: Put on one patch and leave it on for exactly seven days
Week 4: Do not put on a patch this week
Choose a place on your body to put the patch:
Always put your patch on clean, dry, hairless skin
Put it on the buttock, abdomen, upper outer arm or upper back - places where it won’t be rubbed by tight clothing.
Never put the patch on your breasts
Consult your Patient Information Leaflet for detailed instructions on how to place the Evra patches.
Important information to follow when using the patch:
Change Evra on the same day of each week. This is because it is designed to work over 7 days
Never go without wearing a patch for more than 7 days in a row
Only wear one patch at a time
Do not cut or tamper with the patch
Do not put the patch on skin that is red, irritated or cut
To work properly the patch must stick firmly to your skin
Press the patch down firmly until the edges stick well
Do not use creams, oils, lotions, powder or makeup on the skin where you are placing a patch or near a patch you are wearing. This may make the patch come loose
Do not put a new patch on the same area of skin as the old patch. If you do you are more likely to cause irritation
Check each day to make sure the patch has not fallen off
Keep using the patches even if you do not have sex very often
