Summary

The lay summary the sponsor registered on ClinicalTrials.gov.

The purpose of this study is to compare the effects (good and bad) of subantimicrobial dose doxycycline on the irregular bleeding women experience when taking continuous oral contraceptive pills. This research is being done because currently, there is no effective treatment for this condition. Findings from this study could help to decrease the side effects of birth control pills and decrease unplanned pregnancies.
