Combined oral contraceptives remain in 2020 the most used contraceptive method in Switzerland and Europe, and are found in about half of venous thromboembolism (VTE) occurring in women aged up to 50 years. In this narrative review, we describe the determinants of the VTE risk, related to the types of oral contraceptives and to genetic or acquired risk factors of users, while summarizing several current recommendations of prescription for contraceptives. The complex management of contraception at the time of VTE should be discussed with patients, in order to minimize the risks of undesired pregnancy, abnormal uterine bleeding and recurrent VTE.
