A 36-year-old woman in Texas has filed an Ortho Evra lawsuit against the manufacturers of the birth control patch after suffering serious side effects from using the product. Karenetha Easterwood’s lawsuit alleges that she suffered a pulmonary embolism—or blood clots in the lungs—after using Ortho Evra.

Since the Ortho Evra patch was released in 2002, Ortho-McNeil Pharmaceuticals has been forced to issue several warnings about the patch due to the risk of side effects experienced by some patients. Because the patch releases 60% more estrogen into the body than birth control pills, women who use Ortho Evra are at double the risk of blood clots. This increased risk also places women in danger of other Ortho Evra side effects, including heart attack, stroke and deep vein thrombosis.

In the lawsuit filed by her Ortho Evra attorney, Easterwood alleges that the manufacturers of the birth control patch misled consumers about its safety, and failed to properly warn patients about its dangers until January 2008. In that month, conflicting information about the dangers of Ortho Evra compared with the pill was removed from the patch’s warning label. The manufacturers also added information about the increased risk of deadly blood clots faced by women who use Ortho Evra.
