Although the Ortho Evra patch is about 99 percent effective at preventing pregnancy, according to the American Pregnancy Association, it does have its disadvantages. Women considering the use of Ortho Evra should discuss these issues with a doctor before deciding whether this birth control patch is right for them.
Skin Irritation
A woman wears the Ortho Evra patch on her skin for long periods of time, so irritation around the application site can occur, especially in women with sensitive skin. In fact, irritation around the application site was one of the side effects that caused women to discontinue using the product during clinical trials, according to the Ortho Evra product information sheet. Although most skin irritations will be mild, women with severe skin blistering or skin changes should call a doctor immediately.
Blood Clots
The Ortho Evra patch exposes women to about 60 percent more estrogen than an average birth control pill containing 35 mcg of estrogen, according to the Ortho Evra product information sheet; this raises the risk for blood clots. Although this risk applies to every woman who takes Ortho Evra, women who have a history of blood clots may be particularly susceptible and should not use Ortho Evra.
Side Effects
Side effects that commonly occur with other hormonal birth control medications also may occur with Ortho Evra use. Side effects include breakthrough bleeding, breast tenderness, headaches, nausea, abdominal pain, vomiting and changes in mood or emotional state.
Decreased Effectiveness
Ortho Evra may not be as effective in women who weigh more than 198 lbs., the American Pregnancy Association states. Women weighing more than this should talk to their doctors before using Ortho Evra. Certain antibiotics and other medications may also reduce Ortho Evra's effectiveness.
Weekly Application
Although some women see the weekly application of Ortho Evra as easier than having to remember to take a pill every day, others may struggle with remembering to change the patch each week. Not changing the patch on time compromises the product's effectiveness. A long-lasting or permanent method of birth control should be considered in these cases instead.
Serious Risks
Using Ortho Evra may cause rare, but serious, risks such as strokes, heart attacks, gallbladder disease, cancer and even death. Women who have a history of high blood pressure, obesity, diabetes and other serious medical conditions may be more likely to experience these risks. A person who smokes or is older than 35 using the product may also be at higher risk for these complications.
