VTE risk with contraceptive vaginal rings

Women using contraceptive vaginal rings have a six times increased risk of developing venous thromboembolism (VTE), a study has confirmed for the first time, but an Australian expert says there is "no cause for alarm".

One of the largest studies into the subject to date found women using vaginal rings had a 6.5-fold higher risk of thrombosis compared to women not using hormonal contraception.

This translates to 7.8 confirmed venous thromboses for every 10,000
