[Combined Hormonal Contraception - Which Pill for Which Patient?].

Combined Hormonal Contraception - Which Pill for Which Patient? Abstract. Combined hormonal contraceptives (CHC) are a valuable and highly effective option in contraceptive counseling. Methods and preparations available in Switzerland are combined oral contraceptives (COC), vaginal rings and transdermal patches. All preparations contain an estrogen and a progestin component. The estrogen component mainly consists of the synthetically produced ethinylestradiol (EE), although newer COC may contain natural estrogens such as estradiol (E2) and estetrol (E4). For the progestin component, a variety of luteal body hormones are available, which enable the health care professional to prescribe a "tailored" product for the patient due to their different partial effects. The individual thromboembolism (TE) risk should always be considered and taken into account when prescribing CHC.
