Daimler-35 is an oral contraceptive, and according to current clinical data, all hormonal oral contraceptives can increase the incidence of blood clots. Epidemiological studies have shown an increased risk of venous thrombosis and thromboembolic disorders such as deep heart attacks, venous thrombosis, pulmonary embolism and stroke, although these events are less likely to increase. According to currently available data, the risk of venous thromboembolism is highest during the first year of use of Daimler-35, and increases when the pill is started again, or when the same or different types of contraceptives are used again, with the increase in risk occurring mainly during the first three months according to currently available data. In conclusion, the risk of thrombosis with hormonal contraceptives is 2-3 times higher than in women who do not use hormonal contraceptives and are not pregnant, but because once deep vein thrombosis occurs, it often leads to malignant consequences such as pulmonary embolism. Therefore, in the event of leg edema, a prompt visit to the vascular surgery department and a venous ultrasound of the lower extremities should be performed.
