Patch-Transdermal Contraception

How the Patch Works


The birth control patch is a thin, stick-on, square, 1.75 inch patch that allows hormones to enter the blood stream through the skin. Like birth control pills, a combination of hormones in the patch stops your body from releasing an egg, so no eff can be fertilized. The hormones also cause the liquid at the opening of the uterus to thicken which can stop sperm from getting into the uterus.

How to Use the Patch
The patch is a once-a-week method of birth control on a 4 week cycle. A new patch must be used each week for 3 weeks. Bleeding is expected during the 4th week when no patch is used. The patch is placed on healthy skin on the abdomen, buttock, lower back, upper outer arm or upper torso where it will not be rubbed by tight clothing. It is replaced on the Same day of the week for 3 weeks. The 4th week is patch-free. There should never be more than a 7-day patch-free time between patches. Follow the written instructions that come with the patch.

Effectiveness
Because this method of birth control is relatively new, the research for effectiveness rates is not as extensive as for other hormonla methods. Currently, the perfect use effectiveness rate is 99%; fewer than 1 woman out of 100 will get pregnant when using the patch the correct way. There may be an increased risk of pregnancy for women who weight over 200 pounds.

Benefits of the Patch
The patch is small, thin and smooth and can be worn under your clothes. You only have to change it once a week and you can wear it in a different place each week. It stay s on while you shower, bathe, swim or exercise. Warm, humid conditions do not decrease its sticking power.

Potential Side Effects & Disadvantages
The side effects may include breast tenderness, nausea, headache, menstrual cramps and abdominal pain. They can also include skin reactions where the patch is placed. Using the patch will not give you protection against HIV (AIDS) or sexually transmitted infections (STIs) such as chlamydia, herpes, genital warts, gonorrhea, hepatitis B and syphilis.

Potential Risks

Some women should not use the patch because of specific health conditions. If a woman has a history of cardiovascular disease, it is recommended that she not use the patch. Ask your health provider. Cigarette smoking increases the risk of serious cardiovascular (blood clot, heart attack, stroke) side effects, especially for women over 35. Women who use combination hormonal contraceptives are strongly advised not to smoke.
