Side Effects of Ortho Evra

Ortho Evra is easy to use--simply apply a new patch directly to your skin once a week for three weeks, and then remove the patch for the fourth week when you have your period. Ortho Evra contains estrogen and progestin, and clinical studies have shown it to be 99 percent effective in preventing pregnancy when used properly. Surveys by the manufacturer, Ortho-McNeill-Janssen, found that 95 percent of users were satisfied with the product. According to Planned Parenthood, a prescription to Ortho Evra costs about $15 to $50 per month.

The side effects of Ortho Evra are similar to those of the birth control pill. According to the American Pregnancy Association, users of the patch may experience headaches, weight gain, nausea, breast discomfort and yeast infections. Some users have also reported irritation of the skin where the patch is applied. According to a study conducted at Brown University, 18 percent of users reported some degree of nausea, and an additional 18 percent reported breast tenderness while using the patch, making these the two most common side effects.

Ortho Evra can cause serious side effects in some women, including heart attacks, strokes and blood clots. These dangerous side effects are very rare, and are seen most often in women over the age of 35. Also, if you are a smoker you are strongly advised to quit before you start using the patch, as smoking greatly increases your risk of developing one of these serious side effects.

Studies have shown that women using the Ortho Evra patch have a greater risk for common side effects of hormonal birth control than users of birth control pills. Since the patch delivers hormones directly through the skin, users typically receive greater doses of estrogen. According to the manufacturer, Ortho Evra users receive approximately 60 percent more estrogen than they would with the typical birth control pill. This increases the risk of side effects, especially blood clots. One study published in the "American Journal of Obstetrics and Gynecology" found that women using the patch had double the risk of developing blood clots compared to users of birth control pills.

The FDA has determined that Ortho Evra is a safe and effective way to prevent pregnancy, but always discuss your birth control options with a doctor. Your doctor can evaluate the risks and benefits of Ortho Evra for your individual needs and provide a prescription. If you use Ortho Evra and develop a severe headache, blurred vision, chest discomfort or severe pain in your legs, you should get medical attention immediately.
