Use of Continuous Oral Drospirenone for Menstrual Suppression in Adolescents.

Purpose: To describe experiences of adolescents taking continuous drospirenone (DRSP-C) oral contraceptives, without placebo, for menstrual suppression, including breakthrough bleeding and other side-effects.

Methods: This was a retrospective chart review of adolescents prescribed DRSP-C for menstrual suppression. Demographics and indications for DRSP-C were collected on the visit where DRSP-C was prescribed. Data through the final follow-up visit during the study period included documented effects and side-effects of DRSP-C and continuation of therapy. Statistical analyses were primarily descriptive.

Results: Patients prescribed DRSP-C were included (n = 136). Dysmenorrhea was the most common indication for DRSP-C (58.8%, n = 80/136) followed by endometriosis (44.8%, n = 61/136). The median time on DRSP-C for the 116 patients who were able to initiate treatment was 12.3 months (interquartile range [IQR] 6.8, 17.4). Patients trialed, on average, 2 other forms of menstrual management before starting DRSP-C (IQR 1, 3). Pelvic pain or dysmenorrhea resolution or improvement was reported in 84.6% (44/52) of dysmenorrhea patients, and 77.8% (28/36) of pelvic pain patients. Almost half of patients reported breakthrough bleeding on DRSP-C (41.3%, n = 48/116); however, only 11 patients (42%, 11/26) discontinued DRSP-C because of it. Within the study period, 22.4% (n = 26/116) of patients discontinued DRSP-C, with a median treatment duration of 101 days (IQR 71, 157). Among patients who discontinued DRSP-C, the most common reason was breakthrough bleeding (42%, n = 11/26).

Discussion: DRSP-C for menstrual suppression was well tolerated in adolescents, with most patients reporting resolution or improvement of their indication for taking DRSP-C. Findings demonstrate DRSP-C is a viable option for menstrual suppression in adolescents.
