Evra works in a similar way to the combined pill. It contains norelgestromin and ethinylestradiol which are synthetic versions of the hormones progesterone and estrogen. These hormones are released into the bloodstream to prevent ovulation from occurring each month, overriding your natural menstrual cycle. They also work by thinning the womb lining and thickening the cervical mucus to make it difficult for sperm to enter.
Evra is more than 99% effective when it's used correctly. Factors which can affect it include forgetting to change the patch on time or starting a new one too late after your 7 day break. It has the advantage over the pill of not being affected by vomiting and diarrhoea and you don't need to remember to take it everyday.
If you apply the patch within 24 hours of getting your period then it will start to work straight away. You can apply it after the first day of your period but you won't be fully protected against pregnancy for the first 7 days. In this case, you will need to use a condom or diaphragm during this time period.
While Evra is used primarily for preventing pregnancy, it also has the advantage of making your periods lighter, regular and less painful, alleviating the symptoms of PMS. This may also provide relief for women with endometriosis.
Each contraceptive patch lasts for one week. After each week, you remove the patch and apply a new one until you reach week 4. This is where you have a week off from the patch and have your period.
You can use Evra for period delay in the same way as the combined pill. Instead of having a patch free week at the end of the third week in your cycle, remove the third patch and apply a new one right away. This will then be day one of your patch cycle so you should continue to use the patch for a further 3 weeks. Ensure that you remove your third patch on time and replace it with a new one. Leaving it on too long will leave you at risk of pregnancy as each patch only lasts for one week.
The active ingredients contained in Evra are: norelgestromin and ethinylestradiol.
The other ingredients are: backing layer: low-density pigmented polyethylene outer layer, polyester inner layer; middle layer: polyisobutylene/polybutene adhesive, crospovidone, non-woven polyester fabric, lauryl lactate; third layer: polyethylene terephthalate (PET) film, polydimethylsiloxane coating.
The best time to start Evra is on the first day of your period as you will be protected from pregnancy right away. You can apply your first patch later in your cycle but if you do, you'll need to use an additional barrier method of contraception for the first 7 days of using Evra.
Each Evra patch is worn for 7 days. When you reach day 8, remove it and apply another one right away. You should do this for 3 weeks in a row before having a 7 day break. This is when you have your withdrawal bleed- similar to your period. After the 7 days, ensure you apply a new patch on time.
The patch can be applied to an area of skin which is clean, dry and relatively hair free. Avoid areas with sore, irritated or sensitive skin or where tight clothing would rub against it. Do not apply the patch to your breasts.
The patch is unlikely to peel off or get dislodged as it's very sticky. You can have a bath or shower as usual and this won't cause it to come off. It also shouldn't be affected by swimming or using a sauna or hot tub. If it does fall off, the action you should take will depend on how long the path has been off for.
If it has been less than 48 hours:
Reapply it if the stickiness is still intact
If the patch is no longer sticky then discard it and apply a new one
Continue using the patch as usual and change it on the same day as usual
If you were using the patch correctly for the previous 7 days your contraception will not be affected
If you are near the beginning of your cycle and you have only been using the patch for 6 days or less, your protection may be affected. In this case, use an additional barrier method of contraception for the next 7 days
If it has been more than 48 hours:
Apply a new patch right away and treat this as day one of your cycle- so you will use the patch for another 3 weeks before having the 7 day break
Use an additional barrier method of contraception for the next 7 days
If you have had sex in the past couple of days, see your GP or pharmacist right away as there is a risk of pregnancy. They can issue you with emergency contraception if necessary.
Each patch lasts for 7 days. Leaving it on too long will have the same effect as it falling off or forgetting to replace it on time. If you have forgotten to remove the patch, the action you should take next depends on where you are in your cycle and how long the patch has been left for.
Week one or two- 48 hours or less:
If the patch has been on for no longer than 8 or 9 days, remove it and apply a new one
Remove the new one on the usual day- as if you had replaced it on time
Your contraception will not be affected
Week one or two- more than 48 hours:
Remove the expired patch and apply a new one as soon as you can
Restart your patch cycle and treat this as day one- leaving the new patch on for 7 days before changing it
Use additional contraception, such as condoms or a diaphragm, for the next 7 days
If you have had sex in the past couple of days, see a GP or pharmacist as you will be at risk of pregnancy
If you forget to remove your patch on time in the third week of your cycle, take it off as soon as possible
Start your patch free week and apply your next patch on your usual scheduled day; as if you had removed your patch on time
You won't have a full patch free week and your contraception will not be affected
You might still get your withdrawal bleed but you may not. This is normal in this instance and does not mean you are pregnant
After you remove the patch at the end of the third week, you will apply a new one 7 days later. If you forget, what you should do next will depend on how many days late you are in applying the patch.
If it has been less than 48 hours since you were due to apply the patch, put on a new one right away. Take note of the day of the week as this will be your new patch start and change day. Your contraception will not be affected
If it has been more than 48 hours, follow the same procedure and use an additional barrier method of contraception for 7 days, such as condoms or a diaphragm. If you have had sex during your patch free week, you may need emergency contraception and should see your GP or pharmacist right away

Evra works in a similar way to the pill to prevent unwanted pregnancies and produces the same side effects and risks. The Evra patch is not affected by vomiting and diarrhoea like the pill and you do not have to worry about remembering to take it every day.
While Evra is a brand of the contraceptive patch, NuvaRing is a form of contraception called the vaginal ring. It is a soft, plastic ring which is inserted into the vagina. Both contraceptives release estrogen and progesterone into the body in order to prevent pregnancy. NuvaRing lasts for 21 days once it's been inserted, so you do not need to think about it for 3 weeks until it's time to remove it. It does have a risk of falling out and may not be comfortable for women who don't want to touch their vagina. However, the patch can cause skin irritation and can also fall off occasionally. Which method is best for you will depend on what you are comfortable with.
Other forms of combined hormonal contraceptives include the pill and vaginal ring. These type of contraceptives are not suitable for all women however, as they increase the risk of experiencing blood clots. While this is rare, if you have certain medical conditions or medical history, combined hormonal contraceptives will not be safe for you to use. The mini pill is a progesterone only alternative which is safe for most women to use. Barrier methods of contraception include condoms, diaphragm or caps and the contraceptive sponge. These are non- hormonal and produce no side effects. Long-term reversible methods of contraception are the IUD (copper coil), IUS (hormonal coil), implant and injection. The injection lasts for 13 weeks, the implant for 3 years and the coil for 5-10 years depending on the type.
Each Evra patch is 20cm and is square shaped. It appears similar to an adhesive plaster.
The patch looks similar to an adhesive plaster and is beige in colour. You can apply it to any area of your body which is dry and hair free but you should not apply it to your breasts. The drawback to using Evra is that the patch is visible on your skin and will not blend in with darker skin tones.
The patch can cause skin irritation but this can be minimised by applying it to a different area of the body each time. For example, if you placed it on your lower back one week, you may want to apply it to the stomach or bum the next week. Ensure you don't apply it to areas which tight clothing rub against, like the waistband of your jeans. This can increase the risk of skin irritation and may cause the patch to fall off.
The patch is just as effective as the combined pill, being over 99% effective when it is used correctly. This involves applying and changing it on time and replacing it if it does fall off. The patch is also affected by the same medications as the pill but because the hormones are not passing through your digestive system, vomiting will not cause Evra to be less effective.
Evra stops ovulation from occurring so you won't have a natural period while you are using Evra. During your patch free week, you will have a withdrawal bleed similar to your period. Some women using the patch won't always bleed every month. If this happens more than 2 months in a row then you may want to visit your GP to ensure you are not pregnant.
