implanon reasons for removal

BACKGROUND: The study was conducted to perform a direct comparison of the satisfaction of intrauterine device (IUD) users and Implanon users after 6 months. STUDY DESIGN: Women were recruited to this study in the contraception clinics of Southern Health and Family Planning Victoria. Each woman completed a questionnaire at the time of starting her contraception with either an IUD or Implanon. Women were sent a follow-up questionnaire after 6 months to assess their satisfaction with their chosen method of contraception...

PURPOSE: Implanon is a rod-shaped hormone implant which leads to reliable contraception. The rod is implanted in the subcutis of the upper arm and is usually removed easily after its effective period. In the scenario where the rod is not palpable, the removal of the rod can be difficult or impossible. The purpose of this study was to evaluate the reliability of US in locating non-palpable Implanon implants and to investigate the optimal technical parameters for determining the location...

BACKGROUND: The single-rod Implantable contraceptive method, called 'Implanon', has been introduced for use in Thailand since the 1990s. The outstanding attribute was that it requires only a few minutes for insertion and removal as it has only one capsule. The single-rod implant was used in women at Siriraj Hospital in 2006. The present study looked at characteristics of women, complications of insertion and removal, menstrual events that occurred to women during one year of use and reason for removal of the method...

OBJECTIVES: To evaluate the tolerability and clinical safety of the subdermal, long-acting hormonal contraceptive Implanon. METHODS: This integrated safety analysis included 11 international studies concerning Implanon (68 mg etonogestrel) of which 10 had a duration of at least two years. Assessments included reports of adverse events (AEs), reasons and rates of discontinuation, insertion/removal complications, and the condition of the implant site. Metabolic and coagulation parameters are briefly discussed to fully describe the clinical safety profile...

OBJECTIVES: We describe removal procedures for etonogestrel contraceptive implants in the operating theater. In addition, we discuss the management of removal of contraceptive implants that are difficult to palpate or are impalpable. DESIGN: We conducted a retrospective single-center case series analysis of Implanon removals conducted at a university hospital between January 2002 and April 2005. MATERIALS AND METHODS: We analyzed case notes for 28 patients who had their contraceptive implant removed in the operating theater...

OBJECTIVES: Implanon was introduced in the UK in September 1999. We present here the results of our first 106 Implanon insertions, performed over a period of 18 months. The aims of the study were to study the clinical and demographic profile of Implanon users, to assess the continuation rates of Implanon in the local population, and to identify the reasons for removal. METHODS: This was a case note-based study in which the data were transferred to a standardised pre-tested proforma...

AIM: To describe Australian women's experiences and acceptability of etonogestrel releasing subdermal contraceptive implant (Implanon). METHODS: Six hundred and fifty-one women were recruited at the time of implant insertion and asked to complete a self administered questionnaire immediately after insertion and at 3, 6 and 12 months after insertion. RESULTS: Four hundred and seventy-five women aged 15-50 years responded at least once. Forty-one women had the device removed before 3 months, 48 between 3-6 months, and 75 between 6-12 months...

DESIGN: A multicenter, retrospective study of the single-rod contraceptive implant, Implanon (NV Organon, Oss, The Netherlands), was carried out in Switzerland in 1183 women. METHODS: Assessments included duration of use, bleeding pattern, side-effects and subjective acceptability and satisfaction with the method. RESULTS: A total of 991 women (84%) had at least one follow-up visit and 306 (26%) had two visits with a mean duration between insertion and follow-up of 224 days (7...

BACKGROUND: Endometriosis is one of the commonest benign gynaecological disorders and has a peak incidence between 30 and 45 years of age. Treatment options are medical or surgical, depending on the location and extent of the disease and the woman's childbearing aspirations or need for contraception. Over the past five decades several formulations of progestogen have been used to treat endometriosis. METHODS: Our study was not planned research but a series of case studies of women with severe symptoms of endometriosis treated in an innovative way with a new long-acting progestogen contraceptive system (etonogestrel subdermal implant) which could reasonably have been expected to have a favourable effect on their disease and its symptoms...

OBJECTIVES: To estimate the exact satisfaction of women toward Implanon, the sole contraceptive implant available in France. To clarify the indications of this type of contraception. MATERIAL AND METHOD: Among a population of 182 women with Implanon" inserted in a same family planning service between May 22, 2001 and February 14, 2003, 108 women agreed to answer a questionnaire of satisfaction. Implants were inserted in one third of cases after childbirth, in another third after abortion...

OBJECTIVE: Implanon (NV Organon, Oss, The Netherlands) was released in the United Kingdom towards the end of 1999. This survey elicited the experiences of women who had the new implant inserted in three family planning services in North Trent, UK during the first year after its introduction. METHOD: A previously piloted questionnaire was sent to all Implanon users who had the devices fitted in the three services between December 1999 and December 2000. Returned questionnaires were analyzed...

AIMS: The aims of the study were three-fold, namely to assess continuation rates with Implanon fitted in clients from three contraception and sexual health services; to identify factors associated with early removal of Implanon; and to assess clinician compliance with recommended practice in counselling and insertion. METHODS: Retrospective review of client records, and comparison with audit criteria. Postal survey. MAIN FINDINGS: One hundred and ninety women had Implanon inserted in the study period...

Progestogen-only contraceptive implants are highly effective. In most studies, 5-year cumulative pregnancy rates are less than 1.5/100 women for Norplant and Norplant II. No study has yet reported any failures with Implanon. Weight over 70 kg and age at insertion under 25 years both increase the failure rate of Norplant and Norplant II; however, data are as yet lacking for Implanon. The effectiveness of other progestogen-only implants for which there are as yet few data are unlikely to be any different. Continuation rates are high compared with other hormonal methods and with the intrauterine device...

This 3-year study investigating the contraceptive efficacy and tolerability of Implanon in 635 volunteers demonstrates that it was well tolerated and had excellent, reversible, contraceptive efficacy. No pregnancies (Pearl index, 0; 95% CI 0.0-0.2) occurred during 1,200 woman-years of exposure. Irregular bleeding, mainly frequent and prolonged, was the primary reason for discontinuation (19.0%). Infrequent bleeding (29-51%) was the most common bleeding disturbance. Adverse events, other than bleeding irregularities, were generally mild to moderate in intensity and resulted in 9...

To compare the contraceptive efficacy, tolerability, and bleeding patterns, 200 healthy female volunteers received, in an open, comparative, randomized, multicenter study in China, either a single-rod (Implanon) or a six-capsule (Norplant) contraceptive implant for 2 years with an optional extension of up to 4 years. Women were exposed to Implanon for 341.6 woman-years and Norplant for 329.1 woman-years. There were no pregnancies during the study. Per 90-day reference period, the median number of bleeding/spotting days with Implanon decreased from 33...

An open, multicentre study was performed to assess efficacy, safety and acceptability of the single-rod contraceptive implant Implanon. The study involved 635 young healthy women, who were sexually active and of childbearing potential. The women were followed up every 3 months over the entire study period. Originally the study was designed for 2 years, but was extended to 3 years in a group of 147 women from two centres. Altogether, 21 centres in nine different countries participated. The average age of the women was 29 years (range 18-42 years), of whom 83...

Subdermal contraceptive implants involve the delivery of a steroid progestin from polymer capsules or rods placed under the skin. The hormone diffuses out slowly at a stable rate, providing contraceptive effectiveness for 1-5 years. The period of protection depends upon the specific progestin and the type of polymer. Advantages of progestin implants include long term contraceptive action without requiring the user's or provider's attention, low dose of highly effective contraception without the use of estrogen, and fertility is readily reversible after the removal of implants...
