What is the contraceptive patch - Evra?

Evra is the first contraceptive patch. It contains 150microg norgestromin + 20 microg. Ethinyl Oestradiol. This patch is applied once-weekly for three weeks with one week with no patch applied.

Evra is just as effective as the combined oral contraceptive pills.

As 80% of the hormone is still present after 7days it is advised that the patch should not be flushed as there is a risk of water contamination.

Symptoms associated with the combined pill such as mastalgia dysmenorrhoea and breakthrough bleeding may be more common in early cycles than with COP.

This patch should be applied to the back of the shoulder, low down on the abdomen, upper arm or buttock. Once applied pressure should be applied for ten seconds. There is no need to remove it when bathing. At each change of patch a different site should be used.

When first used an Evra patch should be applied on the first day of your period and it will provide immediate protection. If you forget to change the patch after seven days in the middle of a course but you remember within 48 hours then you may change the patch and no further action is required. If there is more than a 48 hour delay then you should apply a new patch and use a barrier method for the next seven days.

The arrival of a new mode of administration in contraception should be welcomed although it will take a while before we learn how well it will be received. It provides an option for those who have had problems with a variety of oral preparations. Its success will be measured by the number of women who wish to try it on recommendation of their friends and relatives.
