title: Oral contraceptives in adolescent women.
abstract: Taking into account the biological and psychosocial changes during the transition from childhood to adulthood adolescents would need a contraceptive method which ideally would be very effective, independent of compliance, without major health risks during use and no negative impact on the future health of the adolescent, protective against STI, favorable for bone development, with no or only few side effects and having some preventive and therapeutic potential with respect to frequent health problems of adolescent girls. Combined oral contraceptives (COC) used regularly and consistently have a more than 99% efficacy to prevent a pregnancy. COCs have a very low health risk (almost exclusively thromboembolic disease) which seems to differ marginally with respect to dosage and type of the components. Progestogen only oral contraceptives do not have any major negative health impact. The leading side effect is irregular bleeding which in COC users is mainly during the first 3 months and in progestogen only users during the period of use. Other side effects are reported but their frequency is similar to placebo. COC protect against endometrial and ovarian cancer and they may have beneficial effects on a variety of menstrual complaints and acne, which are frequent problems during adolescence. To be effective COCs have to be taken regularly which is frequently not the case. This diminishes considerably their effectiveness depending on the individual compliance. They do not protect against STI and may even have an inhibitory effect on the use of condoms. For most adolescents the risk benefit profile of oral contraceptives is favorable and makes this method valuable. At the same time the prescription of oral contraceptives for adolescents need to be individualized by taking into account the individual risk/benefit profile. Specialized counseling with a high degree of confidentiality adapted to the knowledge and needs of the individual adolescent is desirable.
