The contraceptive patch may be unsafe
Office of the Food and Drug Administration warned women using a popular contraceptive patch Evra, he may release more hormones, and therefore, to a greater extent to increase the risk of dangerous side effects than previously thought.
Previously, experts believed that the risk of side effects when using the contraceptive patch is approximately the same as in the reception of hormonal contraceptive tablets. However, recently published an official warning, which states that women who use the contraceptive patch, get about 60% more estrogen than women who take regular birth control pills.
Evra patch went on sale in 2002; This event was accompanied by an active advertising campaign, in particular, it was hard not to see at least one poster or video, where to try the new drug offers a beautiful, slender models. Evra rather quickly gained popularity; Today, many women find it most convenient means of contraception.
While most of hormonal contraceptive pills
Hormonal birth control pills - a modern method of preventing preg
contains about as much estrogen as in the patch Evra, hormones from the patch goes directly into the bloodstream, while pills first pass through the gastrointestinal tract and partially recycled. As a result, women using patches, estrogen levels in the body may be much higher than normal. For the same reason, experts say, these women are three times more common side effects of contraceptive patch - for example, the formation of blood clots, which sometimes leads to the death of patients.
It is estimated that in one year in the US alone more than a dozen patients aged little younger and a little over 20 years old, died from the effects of the formation of blood clots caused by the use of a contraceptive patch. Significantly more women thrombosis

also had very serious consequences, but they managed to survive.
Company Ortho McNeil, which manufactures the patch Evra, is working with the Office of the Food and Drug Administration; its representatives emphasize that doctors should give patients detailed information on the risks associated with the patch.
Since then, as a patch Evra went on sale, they are used by millions of women. There are currently already filed several lawsuits from relatives of patients in whom the use of evryi resulted in death. The situation is aggravated by the fact that, as it became known in 2003, Ortho McNeil management refused to pay for a study to compare Evra patch to the pill Ortho-Cyclen production of the same company. Evidence suggests that this decision was taken because of the high probability that the results of the study may not be in favor of evryi. However, the company said that the decision on studies made on the basis of their potential scientific value.
At the same time, recent studies have confirmed once again that the use of contraceptive patch is absorbed much more estrogen

. Furthermore, when a woman is protected against pregnancy by means of tablets, hormone levels reaching a maximum of one or two hours after ingestion of the tablet. For 12 hours later, estrogen levels are getting pretty low. When using the contraceptive patch, on the contrary, estrogen levels remain elevated 24 hours as hormones enter the body permanently.
Maybe Ortho McNeil employees will be engaged in (or have engaged in) the improvement Evra patch - it is clear that he should devote less hormones to be considered safe for women. At the same time, some experts recommend that women today refuse to use Evra contraceptive patch and switch to the more traditional and less harmful contraceptives. They emphasize that the preparation of such high doses of hormones totally unjustified - it does not increase the effectiveness of contraception, and can cause serious, in some cases - irreparable harm.
