Summary

The lay summary the sponsor registered on ClinicalTrials.gov.

Irregular or prolonged menstrual bleeding and/or spotting are common side effects in patients using progestin-only hormonal contraception such as levonorgestrel implants (Norplant). Doxycycline, a drug approved by the Food and Drug Administration (FDA) to treat gum disease, may reduce the occurrence of uterine bleeding and spotting in women who use Norplant. This study will evaluate the effects of doxycycline on uterine bleeding/spotting in women using Norplant.
