Some non-oral hormonal contraceptives, such as vaginal rings,implants and skin patches carry a higher risk of venousthromboembolism - blood clots - when compared to oral contraceptivepills, researchers from the University of Copenhagen revealed inthe BMJ (British Medical Journal) . The authors wrote that some patients should change over to oral,hormonal contraceptives to reduce their risk of developing clots. Venous thrombosis is a collective term for DVT ( deep vein thrombosis ) and pulmonary embolism . The researchers explained that most studies have focused on theclot risk for females on oral contraceptive pills. There are veryfew studies that focus on other contraceptives; referred to asnon-oral hormonal contraceptives. Non-oral hormonal contraceptives release hormones into the bodymore continuously. Professor jvind Lidegaard and colleagues set out to determinewhat health effects, specifically venous thrombosis, non-oralhormonal contraceptives have on Danish females aged between 15 and49 years, dating from 2001 to 2010. None of the women in the studywere pregnant or had any medical history of cancer or blood clots before the study started. They took into account a number of factors which could distort thefindings, including the women's education level and their age. Non-oral hormonal contraceptives, such as the vaginal ring, arelinked to a higher risk of developing blood clots, compared to oralcontraceptive pills Over a period of 9,429,128 observation years, a total of 3,434diagnoses of first-time venous thrombosis were made. The authorsreported the following findings for females aged from 15 to 49years: 2 venous thrombosis events per 10,000 exposure years for those notusing any type of hormonal contraception 6.2 venous thrombosis events per 10,000 exposure years for those ona levonorgestrel-containing combined oral contraceptive pill 9.7 venous thrombosis events per 10,000 exposure years for thoseusing a contraceptive skin (transdermal) patch 7.8 venous thrombosis events per 10,000 for those using a vaginalring Women using a progestogen-only subcutaneous implant were found tohave a slightly higher chance of blood clots Women using a progestogen-only intrauterine device either had nohigher risk at all, or possibly a lower risk Women who used a patch or vaginal ring for a long time did notexperience any reduced risk later on. The researchers worked out that of the women they studied, 2,000 ofthe vaginal ring users and 1,250 of the skin patch users shouldswitch over to a combined levonorgestrel-containing oral pill toreduce the risk of a venous thrombosis event in one year.
