A new study suggest that using a vaginal ring may increase the chance of a blood clot.
May 13, 2012- A recent Danish study released on Friday reviewed information on the risks of contraceptive rings and patches for blood clots among all non-pregnant Danish women between the ages of 15 and 49 for the ten year period from 2001 to 2010.
Researchers found over 3,430 confirmed diagnoses of the condition venous thrombosis, which is a clot that blocks an artery or vein. The risks of contracting blood clots when using pills that contain drospirenone first became known in 2010 however, risks involving vaginal rings and skin patches had not been studied.
When a blood clot forms and flow of the blood is blocked it can result in the person having a heart attack if the clot is in an artery supplying the heart. If the same thing happens in an artery that supplies blood to the brain, the person could suffer a stroke.
Researchers came to the conclusion that the 2,000 women that used vaginal rings and 1,250 that used the skin patch should change to oral contraceptives that contain levonorgestrel. They said the increased risk was modest, for the contraceptive implants.
