Stronger Clot Warning for Patch

New labels will strengthen a blood clot warning for the birth control patch Ortho Evra. They will say that the patch leads to a higher risk of blood clots than birth control pills. The U.S. Food and Drug Administration ordered the change January 18. It was prompted by a study that showed a higher risk of clots in women ages 15 to 44 who used the patch. The Associated Press reported on the decision.
