Long-Acting Reversible Contraception (LARCs) has the potential to decrease unintended pregnancies but only if women can easily access a requested method. Retrospective electronic chart review identified women desiring LARC placement over a one-year period ending 31 December 2016. Most of the 311 insertions were for family planning, with 220 new insertions and 60 replacements. Delays occurred in 38% ( n = 118) of patients, averaged 5 ± 5 weeks, and 47% received interval contraception. Reasons included absence of qualified provider ( n = 44, 37%), pending cultures ( n = 31, 26%), and Mirena availability...

OBJECTIVE: To assess referral center outcomes with removal of difficult or nonpalpable contraceptive implants using high-frequency point-of-care ultrasonography. STUDY DESIGN: We present a case series examining patients referred to our specialty center from January 2019 through September 2020 for difficult or nonpalpable implant removal. RESULTS: Of the 54 referrals, six had palpable implants and 48 required ultrasonography. We localized 46 (96%) implants in-office, including 13 located subfascially; two Implanon® implants could not be localized...

PURPOSE: In adolescents, concrete thinking may present as avoidance of an immediate, painful or uncomfortable experience despite long-term benefits, which may affect contraceptive choice. In this pilot study, we sought to better understand the pain that adolescents and young adults experience during contraceptive implant insertion. MATERIALS AND METHODS: In this cohort study, we surveyed 30 adolescents and young adults at their implant insertion visit about pre-procedure anxiety and pain experienced during lidocaine injection and Nexplanon™ placement...

PURPOSE: To describe a case of a young woman who presented for fertility preservation and underwent ovarian stimulation with an etonogestrel implant in place. METHODS: A 24-year old, gravida 0, with an etonogestrel implant and newly diagnosed lower extremity sarcoma and DVT desiring oocyte cryopreservation prior to adjuvant chemotherapy and radiation. To avoid delay in her oncologic care and allow for continued use of contraception post-retrieval, the patient underwent controlled ovarian hyperstimulation (COH) without removal of the etonogestrel implant...

Although Nexplanon is one of the most effective and most utilized long-acting reversible contraceptives in Ghana. We report a rare event of Nexplanon failure in a woman with human immunodeficiency virus (HIV) infection in rural Ghana.

BACKGROUND: This study compared a needle-free anesthesia method with traditional local anesthesia for insertion and removal of Nexplanon® long-acting removable contraceptive device. In our clinic, patients often avoid this highly effective form of contraception due to fear of needles. We sought to determine if patients perceived a difference in pain with the injection, anxiety level or pain with the procedure when local anesthesia was given with a needle v/s a needle-free jet injector device...

INTRODUCTION: Nexplanon is a 4 cm rod-shaped barium sulphate coated contraceptive implant with a usual subdermal insertion in the inner non-dominant upper arm. Complications proper to subdermal contraceptive implants are unusual and principally localized and minor, comprising infection at the site of implantation, hematoma, abnormal scar development, or local nerve and blood vessel injuries. Infrequently, contraceptive implant migration can happen, though habitually not far from the site of insertion...

OBJECTIVES: (1) To identify pregnancies associated with the use of the contraceptive implants Implanon and Nexplanon in the UK during two 5-year reporting periods. (2) To classify the possible reasons for device failure in cases reported for each implant. (3) To examine any differences between reasons for pregnancies associated with these products. STUDY DESIGN: Extraction of data from the UK spontaneous reporting system for adverse drug reactions in relation to etonogestrel implants...

OBJECTIVES: We conducted this study to characterize the frequency of insertion-, localization- and removal-related events and their clinically significant consequences among Nexplanon® (etonogestrel radiopaque contraceptive implant) users in the United States during standard clinical practice. STUDY DESIGN: The Nexplanon Observational Risk Assessment (NORA) study was a large, prospective cohort study conducted in the United States. A total of 428 Health Care Professionals (HCPs) who had completed the Nexplanon clinical training program recruited women who were newly prescribed Nexplanon...

Implantable forms of birth control have been used as a means for convenient and effective medication delivery. Nexplanon® (Merck Sharp & Dohme B.V., Haarlem, the Netherlands) is an implantable birth control device placed in the subcutaneous tissue of the upper medial arm during an in-office procedure. The location of the device is usually confirmed by palpation during a physical exam. In cases where the device is non-palpable, imaging may aid in localization. Implantable birth control devices have a characteristic radiologic appearance, and the location of the device can be confirmed by utilizing ultrasound and/or radiography...

Damage to progestin containing contraceptive implants has been reported for Implanon® rods but there appear to be few reports of damage to Nexplanon® rods. This report describes 2 cases of Nexplanon® rod breakage in an 18-year-old female and a 25-year-old female. The literature regarding damaged progestin implants is reviewed. These reports often involve an alteration in menstrual bleeding pattern and patients frequently request removal of bent or broken implants. The overall incidence of rod breakage and impact of damaged implants on contraceptive efficacy is not clear...

The Nexplanon® implant is a commonly used radiopaque contraceptive device that contains progestogen associated with an ethylene vinyl-acetate copolymer resulting in a slow release of the active hormonal ingredient. It is inserted into the subdermal connective tissue and provides contraceptive efficacy for up to 3 years. Device removal for clinical, personal or device "end-of-life span" reasons is straightforward. In rare cases, implant migration can occur locally within centimeters of the insertion site. Distant device embolization is extremely rare and can result in complications including chest pain, dyspnoea, pneumothorax and thrombosis or prevent conception until the active ingredient is depleted...

There has been much discussion about the relationship between hormonal contraceptives and the development of pseudotumor cerebri (PTC). Some have claimed that progestin-containing contraceptives, such as levonorgestrel intrauterine devices, are linked to PTC. However, the relationship and mechanism of PTC following the use of progestin-containing contraceptives remain controversial. We present a case of PTC following implantation of Nexplanon® (etonogestrel) (Merck Sharp & Dohme BV, Haarlem, The Netherlands), a progestin contraceptive...

As the reversible contraceptive arm implants grow more popular, there is an increasing need to recognize the complications resulting from implant migration and removal. This review summarizes the findings of imaging and removal methods. When an implant is lost, the axillary region should be investigated first. If the implant still cannot be found, visualization though different methods have been employed for non-radiopaque implants. Real-time fluoroscopic-guided localization and removal can be accomplished for radiopaque Nexplanon...

OBJECTIVES: Nexplanon® 's new applicator system was designed to limit deep implant placements, known to lead to difficult removals. However, removal difficulties still exist and induce specific and potentially severe complications. Our objective was to identify risk factors associated with difficult removals. STUDY DESIGN: A retrospective single-center study was performed from January 2015 to December 2016. Participants were divided into two groups depending on whether implant was removed during a standard ("standard removal" group) or difficult consultation ("difficult removal" group) after an initial failed removal attempt...

Nexplanon is a long-acting 4cm radio-opaque rod shaped contraceptive device implanted in the subdermal layer of the inner, upper arm. Complications from implantation are uncommon and mostly local and minor, including infection at the implantation site with resulting cellulitis or abscess, hematoma, abnormal scar formation, or local damage to nerves and blood vessels. Intravascular insertion is estimated to be at 1.3 per million Nexplanon implants, and migration and embolization is a rare complication of this device...

Long-acting reversible contraception, which include etonogestrel subdermal hormonal implants, has high efficiency rates in preventing teen pregnancy. Although these numbers are increasing, teens have the lowest long-acting reversible contraception usage rate of any group, which the American Congress of Obstetricians and Gynecologists addressed with recommendations for Nexplanon placement for teens. The American Congress of Obstetricians and Gynecologists has recommended support for increased use and training of practitioners and pediatricians to gain momentum...

STUDY OBJECTIVE: The fracture of hormonal implants, including Implanon, Nexplanon (both from Merck & Co, Inc), and histrelin acetate is rare. Our aim was to describe patient demographic characteristics, mechanisms, and consequences of fractured implants by surveying physicians' experience via listservs and social media. DESIGN, SETTING, PARTICIPANTS, INTERVENTIONS, AND MAIN OUTCOME MEASURES: We developed a Research Electronic Data Capture survey for physicians regarding their experience with implant fracture, including patient characteristics, mechanism of fracture, changes in menstrual bleeding patterns, time from insertion to fracture, and time from fracture to seeking care...
