Bayer: the "Janin" contraceptive raises venous thromboembolism risk by 1.6 times — peak risk during the first year of use.
Bayer, the manufacturer of the combined hormonal contraceptive, has stated that "Janin" increases the risk of venous thromboembolism. A change to the drug’s instructions is expected. According to the published information, products containing the combination of dienogest and ethinylestradiol (as in "Janin") increase the risk of developing venous thromboembolism by 1.6 times compared with products containing other substances — levonorgestrel, norgestimate, or norethisterone.
Bayer’s report states: "The choice in favor of combined hormonal contraceptives with a higher risk of developing venous thromboembolism may be made only after consultation with the woman, ensuring that she fully understands the thromboembolism risk associated with taking the medicinal product ‘Janin’, the medication’s effect on her existing risk factors, and the fact that the risk of developing thromboembolism is highest during the first year of taking such medications."
Studies of 288,122 women showed that among women taking a drug with the above-mentioned composition, 8–11 cases of thromboembolism per 10,000 women are recorded. Among women taking other agents, the figure is 5–7 cases, and among those who do not take contraceptives — 2 cases. In principle, taking contraceptives always carries an increased risk. The most dangerous time is the first year of using any hormonal contraceptive and when resuming use after a break of four or more weeks.
