The hormones are not metabolized through the intestine and liver like the oral pills. Rather, they are transmitted transdermally, through the skin. This results in women receiving much larger doses of estrogen then they would ingest with the pill. The Ortho Evra patch also results in constant exposure to estrogen. With the pill, women have an initial spike which then immediately comes down.
Since the FDA has restricted birth control pills to doses under 50 micrograms of estrogen. This limitation was enforced because of the danger posed to women with that level of estrogen. However, the Ortho Evra patch delivery results in approximately 56 micrograms of estrogen.
Another problem with the birth control patch is associated with the other hormone, progestin. Ortho Evra uses a 3rd generation progestin, known as Norelgestromin.
This third generation progestin is more dangerous than second generation progestin and increases the risk of thrombolic events. Since Ortho Evra was introduced, it remains the only transdermal contraceptive patch. Studies have shown that the risk of developing potentially fatal blood clots and suffering other adverse events is significantly increased with use of Ortho Evra compared with traditional birth control pills. However, the pill had under 1, reported adverse events over a six year period, compared with over 9, adverse events reported for Ortho Evra during just 18 months.
These hormones are chemicals that control different parts of the body, helping to prevent women from becoming pregnant. The patch can be applied on the skin of your outer arm, stomach, back or buttocks. It must be applied once a week, for three weeks straight. Then you have one week with no patch on at all.
During the patch-less week, you will most likely have your period. If you are still bleeding when your new patch day comes around, this is considered normal, just apply a new patch consistent with your weekly schedule. The Birth Control Patch is easy and safe to use. It does not have to be adjusted or taken daily like birth control pills.
Some women may experience some undesirable side effects from using the patch. However, most women adjust to the patch within a few months of using it. This is similar with other forms of birth control too. In addition, the skin may become irritated or have a reaction to where the patch is placed on the body.
Once a woman stops using the patch it can take one or two months for the period cycle to get back to normal. More serious side effects have warning signs. If you experience any of the issues below, contact your health care provider immediately:.
This is because it allows the correct release of hormones into the body. The patch can be less effective for women who are overweight or for women taking other medicines and supplements. Talk to your doctor about which medications you are currently taking and if these will affect the patch. Most women can use the birth control patch safely, but there are some risks associated with it. More serious side effects of the patch are rare and are caused by other medical conditions or medications that the woman is taking.
Contact a doctor or nurse for more information about if the patch is right for you and your specific body. If you forget to take your patch off during week four, just remember to take it off and apply a new patch when the new week starts on patch day.
