Use of hormonal contraceptives in perimenopause: A systematic review.

Hormonal contraceptives have been used in perimenopausal women to manage a variety of symptoms and prevent unintended pregnancy. However, it is unclear what contraceptive regimen is best for these women. To evaluate hormonal contraceptive methods in women experiencing perimenopause using two prespecified outcomes: perimenopausal symptom management and long-term effects. A literature search of PubMed and EMBASE databases was performed (January 1990 to October 2021) using search terms "perimenopause" and "contraception." Relevant full-text articles in English were included. Fifteen clinical articles were reviewed: Fourteen were internationally based, and one study was conducted in the United States. Nine articles evaluated symptom resolution, and six of these nine reported statistically significant changes in favor of treating perimenopausal women with hormonal contraceptives compared with no treatment. Seven studies evaluated long-term outcomes including bone loss and metabolic parameters, and six of these seven showed statistically significant improvements with hormonal contraceptives. Based on limited data and a lack of comparative studies, the use of a levonorgestrel intrauterine device with supplemental low-dose menopausal estrogen has positive results for the management of disruptive perimenopausal symptoms and long-term outcomes. Hormonal contraception in perimenopausal women improves symptom management and long-term outcomes if patients do not have contraindications. When selecting a contraceptive for women in perimenopause, clinicians and pharmacists need to address specific patient risk factors, symptom profiles, long-term risks and benefits, and patient preferences.
