Relationship Between Etonogestrel Concentrations and Bleeding Patterns in Contraceptive Implant Users.

ABSTRACT:

Objective

To estimate whether serum etonogestrel concentrations influence bleeding patterns and related side effects in contraceptive implant users.

Methods

We conducted a prospective cross-sectional study with healthy, reproductive-aged women using etonogestrel implants for 12-36 months. Participants completed a brief questionnaire to assess their current bleeding pattern and any experience of abnormal bleeding with the implant. We then measured serum etonogestrel concentrations. We also reviewed the charts of participants to determine whether a prescription for oral contraceptive pills was ever given for treatment of implant-related bothersome bleeding. We performed multivariable logistic regression to test for associations between serum etonogestrel concentrations and bot
