| Popis: | Introduction. The frequency of side effects when taking combined oral contraceptives (COCs) is still high, which is the reason for refusal to take COCs by women worldwide with a frequency of 30 to 81 %. Management of side effects will help increase the user's adherence to the chosen method of contraception.Aim: to identify approaches to prevent users from refusing to take COCs due to side effects and increase adherence to their use.Materials and Мethods. The search for foreign literary sources in English was carried out in the international bases PubMed/MEDLINE, Google Scholar, Cochrane Library, in Russian in еLibrary database, by keywords: «hormonal contraception», «combined oral contraceptives», «side effects», «adherence». Search depth was 30 years (1992–2022). 437 and 74 articles were identified, respectively, of which the review included 44 manuscripts that satisfied the criteria for inclusion on the topic studied: full-text manuscripts with the results of original studies, systematic reviews and meta-analyses.Results. In the literature, there is a lower incidence of side effects of COCs containing 30–35 µg of ethinylestradiol (tri- and monophasic) compared with 20 micrograms of ethinylestradiol. It was found that the risk of intermenstrual bleeding is 30 % lower when using COCs containing thirdgeneration progestogens compared with second-generation progestogens (relative risk (RR) = 0.71; 95 % confidence interval (CI) = 0.55–0.91) using monophasic combinations as an example. The use of a three-phase COC containing desogestrel (DSG) was characterized by a low incidence of irregular bleeding (3.3 % in the first cycle and a decrease to 2.3 % by the 12th cycle), no effect on physiological parameters, a decrease in blood androgens content and a positive effect on seborrhea and acne, excellent tolerance (2.6% failures due to adverse events). Three-phase COCs are characterized by a lower frequency of intermenstrual bleeding (by 2 times) and amenorrhea (by 3 times) compared with other COCs. A positive effect on reducing the frequency of irregular spotting and breakthrough bleeding was shown when switching from a COC of another composition to a three-phase one containing DSG, and continuing to use it.Conclusion. A three-phase COC containing DSG continues to be a topical hormonal contraceptive for women both for the first time and when switching from another COC due to side effects, including those associated with menstrual irregularities. |
