Background: Contraceptive injection is the most common contraception used in Indonesia. Among the contraceptive injections, depomedroxy progesterone acetate (DMPA) is the most effective method with pregnancy rate of 0,3 pregnancy in 100 women annually. Abnormal uterine bleeding (AUB) is a common side effect occurred in DMPA users which leads to the discontinuation of contraception.Objective: To explore the effect of tranexamic acid on bleeding length for DMPA users with AUB who receive low dose Oral Contraceptive Pills (OCP).Methods: We performed double blind randomized control trial between  two groups to investigate the effect of tranexamic in managing AUB in DMPA users who receive low dose OCP. This study was performed in Dr. Kariadi Hospital Semarang, Indonesia. Forty-four subjects were divided into two groups, equally. Group 1 received 250 mg tranexamic acid four times a day for 5 days and OCP once a day for 28 days, while Group 2 received placebo four times a day for 5 days and OCP once a day for 28 days. Both groups were evaluated for bleeding length during treatment and were analyzed using Mann Whitney for post treatment with tranexamic acid.Results: The mean bleeding length was 5.2±3.62 days and 9.2±6.16 days in group 1 and 2 respectively. These bleeding lengths were significantly different between both groups (p=0.018). The precentage of subjects in whom bleeding was stopped during the first week after initial treatment was significantly higher in  group  1 than group 2 (77,3 % vs 45,5 %, p<0,030).Conclusion: Tranexamic acid significantly reduced the bleeding length in DMPA users who use OCP.

Untuk mengeksplorasi Efektivitas Pil Oral Kombinasi (POK) dalam Pengobatan Perdarahan Uterus Abnormal pada akseptor DMPA. Metode: Kami melakukan percobaan untuk menyelidiki efek pil oral kombinasi dosis rendah dalam pengelolaan PUA pada akseptor DMPA. Penelitian ini dilakukan di Rumah Sakit Dr. Kariadi Semarang, Indonesia. Desain penelitian yang digunakan adalah pra eksperimental. Dua puluh dua akseptor DMPA diberikan terapi POK dosis rendah sekali sehari selama 28 hari (satu siklus), kemudian subjek dievaluasi untuk durasi perdarahan selama perawatan. Variabel bebas dalam penelitian ini adalah pemberian POK dosis rendah dan variabel dependen adalah jumlah hari perdarahan. Hasil: Terdapat penurunan bermakna rata-rata hari perdarahan pada akseptor DMPA dengan PUA antara sebelum dan sesudah terapi POK dosis rendah dari 22,2(4,48) menjadi 9,2 (6,16) hari (p=0,0001). Persentase dari subjek penelitian yang pendarahannya berhenti dalam minggu pertama setelah pengobatan adalah sebesar 45,5 %. Hanya terdapat satu orang yang mengeluhkan efek samping berupa pusing dan mual selama pengobatan Kesimpulan: Pil Oral Kombinasi Dosis rendah dapat mengurangi hari perdarahan pada akseptor DMPA
