An effective, safe, inexpensive and convenient method of contraception is the birth control patch. The patch is a piece of material about 1.75 square inches that sticks firmly to the skin. Once applied to the skin, it releases a combination of the estrogen and progestin hormone which is absorbed through the skin.

The patch is usually worn for a seven-day period, and then a new one is applied. During the course of four weeks a woman applies one patch each week for three weeks. On the fourth week a patch is not worn and a menstrual cycle takes place.

The patch can be worn during any normal daily activity and may be placed on the lower abdomen, buttocks or upper arm. It should never be worn on the breast, however, as the release of the hormones can have an adverse affect on the breast tissue.

A redness or rash may sometimes be experienced at the patch placement site. This is usually mild and is not harmful; however, if it worsens or causes unusually discomfort, it may be necessary to change the placement site. If problems with patch placement continue, however, a health care professional may need to be consulted.

The patch works by releasing the hormones, which results in changing of the uterine lining, thickening of the cervical mucus, and prevention of ovulation. Any or all of these conditions prevents pregnancy from occurring.

There are some risk factors associated with use of the patch. Smoking, being over the age of 35, having a history of heart attacks, strokes, or certain cancers, and having a history of blood clots are some of them.

About 1 in 100 unplanned pregnancies occur each year with the use of the patch, making it one of the most effective birth control methods. However, the patch provides no protection from sexually transmitted diseases. Also, if a patch is removed or falls off during regular use, another form of contraception should be used to prevent pregnancy.

The ability to become pregnant soon after discontinuing use of the patch, not having to take a pill every day, and the possibility of lighter, more regular and shorter periods are some the advantages of the patch. Additionally, the cost of the patch is between $15 and $40 each month, making it an inexpensive method of birth control.
