Evra is a convenient transdermal contraceptive patch used as a birth control method to prevent pregnancy and was introduced in the UK in 2002. Evra patch contains both artificial oestrogen and progestogen (norelgestromin and ethinylestradiol) and works in a very similar way to combined oral contraceptives (the pill) except that only one patch is required per week.
Also known as Ortho Evra, the patch releases a steady dose of hormones into your bloodstream through your skin, for the entire duration of your cycle. Similar to the vaginal contraceptive ring, it is easy to use and low maintenance contraception, providing an alternative for those who may be unable to take the traditional pill.
Ortho Evra's contraceptive hormones are released into the bloodstream through your skin and once they are in your system, they work in the same way as regular combination contraceptives. It prevents ovulation from occurring stopping the egg from being released when it is supposed to. This happens because the hormones in Evra patches, norelgestromin and ethinylestradiol, make the body think that ovulation has already happened.
As an additional measure, the transdermal birth control patch prevents sperm from entering the womb by changing the consistency of the cervical mucus and preventing the womb lining from thickening enough for an egg to attach and grow there.
The three-part process can be summarised as follows:
As with any birth control method, if you do not use the contraceptive patch in time or keep it on for too long, its effectiveness will be compromised. More information regarding this, and what you should do, is detailed below. The patch is also effective if you happen to vomit or have diarrhea as, unlike the contraceptive pill, it is absorbed straight into the skin. Please ensure you speak to your health care provider regarding the best method suited to you before using this hormonal contraceptive.
The Evra contraceptive patch provides women with a convenient alternative to the pill. All you have to do is use a patch every seven days to enjoy complete protection. Similarly to the pill, the Evra patch can provide the following benefits:
The patch is thin and beige in appearance at roughly 5cm x 5cm in size, working in the same way as a nicotine patch by releasing hormones into your bloodstream through the skin, rather than through ingestion.
Evra transdermal patches are used for three weeks (21 days) of your cycle, followed by a seven-day break period, during which you will still be completely protected. You should change your patch every seven days and apply a new patch on day eight. There are three patches in every 1-month supply box.
If you start using the patches within the first 24 hours of your period, you should be fully protected, but if you take use the patch later than that you should wait seven days before having sex or use an additional contraceptive method (such as the barrier method) .
As mentioned, the patch will be of immediate maximum effectiveness if applied within the first to fifth day of your period. Otherwise, use barrier protection or avoid sex for the next week.
There is not any research specific to the contraceptive patch concerning whether patients have forgotten to take off either patch one, two or three, or to apply a new patch after the 7-day break. However, the effects of the combined pill and the contraceptive ring can indicate the consequences as they work in a very similar way.
If you did not use further protection but had unprotected sex, you should consider getting the morning after pill. For further help on obtaining one of two emergency pills, head to our Morning After Pill page.
The contraceptive patch is a sticky blighter that should stay in place securely throughout its seven days of use, even if exposed to humidity or situations which require extreme movement. This includes washing, swimming, exercising and other activities which may cause normal plasters to come off. However, should you experience any problems this is what you can do if it comes off:
Less than 48 hours - Stick your patch back on as soon as possible if it is still sticky. If it has lost its stickiness, throw away and apply a new patch. Do not try to salvage the damaged patch with plasters or tape, as this may decrease its effectiveness. Change to another new patch as initially scheduled.
More than 48 hours - You may not be protected against pregnancy during this period so you will need to use additional barrier protection (such as condoms) for seven days. However, you should still apply a new patch as soon as possible. This will alter your usual change dates.
There is just one dosage for Evra and this has been clinically tested so you're effectively protected against pregnancy whilst posing minimal risk on your health. Ortho Evra contains the active ingredients ethinylestradiol and norelgestromin, synthetic oestrogen and progestogen respectively. The dosage levels are 203mcg for ethinylestradiol and 34mcg for norelgestromin. You can request a prescription for both 3-month and 6-month supplies at HealthExpress.
Some women experience side effects whilst applying the contraceptive patch. Like all contraception, side effects are rare and tend to be temporary, especially when starting a new medication. Common side effects that may be experienced when first using the treatment include:
Rare sides effects of the contraceptive patch include:
Contrary to popular belief, the patch will not make you gain weight, but you should be aware that the change in hormones may affect your eating habits negatively. If you do experience any adverse symptoms, you should always seek further medical advice from your GP.
It is also essential that you inform your doctor or health care provider before using the Evra patch, as research has shown it to slightly increase the risk of blood clots in women compared to the combined pill. For this reason, the FDA have provided a warning on the label to ensure those using it understand the risks and take the correct precautions.
For most women the Evra patch is a safe contraceptive, however, there are some scenarios that make it unsuitable. The Evra patch is contraindicated for women who are:
In other cases women may need to exercise caution when applying the contraceptive patch. You should consult your doctor before starting treatment if you are at risk for or have experienced:
Although the Evra patch is generally well tolerated, caution is usually advised when taking it alongside certain other medications. Most antibiotics do not have an adverse reaction when used at the same time as the Evra patch, but some treatments may make Evra less effective. This includes:
It is always advised to visit your GP before starting a new form of contraception so that they can assess whether this contraceptive option is the best for you, or if an alternative may be more suitable.
If you think you could be pregnant, it is advised to stop using the contraceptive patch immediately. The patch is also not recommended if breastfeeding as it can reduce the amount of breast milk. Because of this, doctors seldom offer the contraceptive patch to new mothers before the 6-month mark.
It is usually advised to wait until the cycle of the patch is complete, then you can stop using it at this point. You should be aware that your normal periods may not resume immediately and/or may take some months to regulate.
If you decide to remove the patch before the end of the cycle for reasons other than becoming pregnant, you increase the risk of an unwanted pregnancy, therefore it is essential that you tell your doctor before you do so. It is recommended that you use an alternative contraceptive method if you have decided against using the transdermal contraceptive patch.
If you are planning to have a baby, it is advised for you to wait for at least one standard period after stopping the use of the Evra patch before trying. This is to ensure that your body has reset to a normal cycle and that you can take the right steps towards pre- and mid-pregnancy care.
If you accidentally have unprotected sex before using or after coming off Evra transdermal patch, you have the option of taking emergency contraception to prevent a pregnancy. This should be done as soon as possible after unprotected sex. The main options available are usually ellaOne (works within five days of intercourse) and Levonelle (works within three days of intercourse).
Please note: if you have already conceived/ are already pregnant, emergency contraception will not terminate this pregnancy but may cause harm to your child. Please seek advice with your doctor to determine your options in case of pregnancy.
The only contraception that will protect you against STIs are barrier methods such as condoms, which are 98% effective when used correctly. Th contraceptive patch will protect against pregnancy, but not STIs (sexually transmitted infections).
