Product Description of the Birth Control Patch:

Please read these two important health warnings regarding the patch: here and here.

The Ortho Evra contraceptive patch is a relatively newer form of reversible contraception. It is a 4 x 4 cm beige patch that sticks to a woman’s skin and continuously releases estrogen and a progestin (female hormones) into the bloodstream. The patch does not protect against any STDs, including HIV.

How to Use the Birth Control Patch:
Each patch is worn on the skin for seven days. A new patch is worn each week for 3 weeks. The fourth week is patch-free, and during this week your period will occur. The patch can be worn on the buttocks, stomach, back or upper arms. The patch works best when it is changed on the same day of the week for three weeks in a row. Pregnancy can happen if an error is made in using the patch — especially if the patch falls off for more than 24 hours or the same patch is left on for more than 7 days.
Failure Rates for the Birth Control Patch:
The patch is considered to be as effective as the birth control pill, with less than one woman out of every one hundred who use the patch getting pregnant with perfect use. It is thought that with improper use that figure rises to eight out of every one hundred women.
Cost of the Birth Control Patch:
Between $30-$40 a month.
Where to Get the Birth Control Patch:
The patch requires a prescription written by a doctor.
Side Effects of the Birth Control Patch May Include:
Recent studies suggest that women using the patch may be at significantly increased risk for blood clots and stroke. If you are currently using the patch, or are considering the patch please discuss this with your physician to determine if the patch is a safe method for you.

other side effects may include:

  • Breakthrough bleeding (between periods)
  • Breast tenderness
  • Headaches and/or nausea as your body gets used to the hormones
  • Skin irritation
Things to Watch Out for with the Birth Control Patch:

The patch is very “sticky”. While this is obviously important so it won’t fall off, some people are irritated by the adhesive.

Because it can be easy to forget, it can also be easy to forget if it has fallen off. Women using the patch need to be careful that it is secure each week for the three week period, and if it does fall off that they follow the instructions appropriately, and use a back up form of birth control until the patch is fully effective.

Who Should Not Use the Birth Control Patch:
  • The patch may not be as effective for women who weigh more than 198 pounds.
  • As with the birth control pill, some common medicines and herbal remedies may make the patch less effective, including yeast infection treatments and St. John’s Wort. For this reason it is important to talk to your doctor about any possible conflict with the patch that may be relevant to you.
  • Women who are 35 or older and smoke cigarettes
  • Women with a history of high blood pressure, some blood clotting disorders, heart attacks, or certain kinds of stroke you should not use the ring.

For other specific concerns talk to your health care practitioner.
