Sažetak
OBJECTIVE: To estimate whether continuous oral contraceptive pills (OCPs) will result in more pain relief in primary dysmenorrhea patients than cyclic OCPs, which induce withdrawal bleeding with associated pain and symptoms. METHODS: We conducted a double-blind, randomized, controlled trial comparing continuous to a cyclic 21-7 OCP regimen (gestodene 0.075 mg and ethinyl estradiol 20 microgram) for 6 months in 38 primary dysmenorrhea patients. The primary outcome was the difference in subjective perception of pain as measured by the visual analog scale over a period of 6 months. RESULTS: Twenty-nine patients completed the study. In both groups, pain reduction measured by visual analog scale declined over time and was significant at 6 months compared with baseline, with no difference between groups. Continuous regimen was superior to cyclic regimen after 1 month (mean difference -27.3, 95% confidence interval [CI] -40.5 to -14.2 ; P<.001) and 3 months (mean difference -17.8, 95% CI -33.4 to -2.1 ; P=.03) of treatment. Secondary outcomes noted no difference between groups in terms of menstrual distress as measured by the Moos Menstrual Distress Questionnaire. After 6 months, there was an increase in weight and a decrease in systolic blood pressure in the continuous group compared with the cyclic group. CONCLUSION: Both regimens of OCPs are effective in the treatment of primary dysmenorrhea. Continuous OCPs outperform cyclic OCPs in the short term, but this difference is lost after 6 months.
