Thromboembolic Disorders and Other Vascular Problems
- Several studies have investigated the relative risks of thromboembolism in women using Yasmin compared to those in women using COCs containing other progestins. Two prospective cohort studies, both evaluating the risk of venous and arterial thromboembolism and death, were initiated at the time of Yasmin approval. The first (EURAS) showed the risk of thromboembolism (particularly venous thromboembolism) and death in Yasmin users to be comparable to that of other oral contraceptive preparations, including those containing levonorgestrel (a so-called second generation COC). The second prospective cohort study (Ingenix) also showed a comparable risk of thromboembolism in Yasmin users compared to users of other COCs, including those containing levonorgestrel. In the second study, COC comparator groups were selected based on their having similar characteristics to those being prescribed Yasmin.
- Two additional epidemiological studies, one case-control study (van Hylckama Vlieg et al. 3) and one retrospective cohort study (Lidegaard et al. 4) suggested that the risk of venous thromboembolism occurring in Yasmin users was higher than that for users of levonorgestrelcontaining COCs and lower than that for users of desogestrel/gestodene-containing COCs (socalled third generation COCs). In the case-control study, however, the number of Yasmin cases was very small (1.2% of all cases) making the risk estimates unreliable. The relative risk for Yasmin users in the retrospective cohort study was greater than that for users of other COC products when considering women who used the products for less than one year. However, these one-year estimates may not be reliable because the analysis may include women of varying risk levels. Among women who used the product for 1 to 4 years, the relative risk was similar for users of Yasmin to that for users of other COC products.
