The AP looked at federal drug safety reports of Ortho Evra. The AP says women on the patch are three times as likely to get a fatal blood clot compared to women on the birth control pill.
The makers of Ortho Evra say the AP's findings are misleading and the validity of the information is uncertain. They also say safety is their first priority and they investigate every report of an adverse effect.
Dr. Joel Maurer of Michigan State University's Women's Healthcare says he was surprised to see the AP's findings, and although it is not a completely scientific study, he will warn patients of the data. He says more studies would help clarify the risks, but it does not look like the Food and Drug Administration will further investigate.
For now, it's recommended concerned patients discuss the issue with their doctor.
