Ten women from various states across the country have filed an Ortho Evra lawsuit in New Jersey alleging serious injuries caused by the birth control patch. In the lawsuit, the women allege that using the Ortho Evra patch caused them to suffer strokes and blood clots, according to their attorney.

The Ortho Evra patch—which is applied to the skin and left on for one week—was designed to be a more convenient form of birth control than traditional birth control pills. However, despite indications that women who use the patch may face an increased risk of blood clots compared with the pill, there are currently no plans from the manufacturer of the patch to issue an Ortho Evra recall.

In their lawsuit, the women allege that the Ortho Evra patch is “defectively designed” and “unreasonably dangerous.” All 10 of the women have experienced long-term health problems after using the patch.

One woman, a 19-year-old from Colorado, developed a 10-inch blood clot in her brain, despite using the Ortho Evra patch for only three months. She has suffered two strokes and frequently gets migraine headaches.
