Low-dose oral contraceptive to re-induce menstrual bleeding in amenorrheic women on DMPA treatment: a randomized clinical trial.

Abstract

BACKGROUND Depot medroxy progesterone acetate (DMPA) is one of the most reliable contraceptive methods with a failure rate less than 0.3 percent. It is injected every three months and Although it has many advantages over many other hormonal contraceptives, But a major disadvantage of it is bleeding disorders which comprise most of the discontinuance reasons. Our Aim was to study bleeding complications of DMPA when used as a contraceptive in Ardabil district and clinical trial of LD and Ethynil oestradiol in controlling these complications. MATERIAL/METHODS All the 917 women who referred to ardabil's health centers for having a DMPA injection for the first time, were entered into a longitudinal study. Those complaining of menstrual cessation were entered into a double blinded randomized clinical trial. Data were collected by means of 9 questionnaires 7 of them used for descriptive and 2 for clinical trial study. Data was analyzed by SPSS statistical package. RESULTS Those DMPA users with a cesarean section history had a higher chance of bleeding complications. Four hundred forty-four of the 917 women receiving the injection discontinued using it before the end of the study period. The main reason for discontinuation (in 70%) was irregular menstrual bleedings and menstrual cessation. In the clinical trial of women with bleeding cessation, 70% of those receiving the LD-OC pill experienced menstrual bleedings again, compared with only 22.7% in the placebo group. The discontinuation rate in the drug group was lower than in the placebo group as well (p < 0.05). CONCLUSIONS Treating menstrual cessation caused by DMPA with LDs, improves the complication and decreases the discontinuance rate.
