Etonogestrel (etonogestrel) — Uses, Dosage, Side Effects & Safety

Drug class: Progestin contraceptive

Overview

Etonogestrel is a type of long-acting reversible contraceptive used to prevent pregnancy. It is most commonly available as a small, flexible rod (implant) placed under the skin of the upper arm, or as part of a vaginal ring. Etonogestrel works by releasing a steady, low dose of hormone that prevents ovulation (the release of an egg from the ovary), thickens cervical mucus to block sperm, and alters the uterine lining to prevent implantation. This medication is highly effective, lasting up to 3 years for the implant and 3 weeks per cycle for the vaginal ring. It is a convenient option for those who want reliable birth control without daily pills. Etonogestrel does not protect against sexually transmitted infections (STIs). Key points: The implant must be inserted and removed by a trained healthcare professional. Most users experience changes in menstrual bleeding patterns. Discuss your medical history and all medications with your provider before starting etonogestrel.
