Combined oral contraceptive treatment for bleeding complaints with the etonogestrel contraceptive implant: a randomised controlled trial

Effect of a single dose of a combination injectable contraceptive for treatment of bothersome uterine bleeding in contraceptive implant(s) users: A randomized double-blind placebo-controlled trial

OBJECTIVES

This study aimed to determine the proportion of participants whose uterine bleeding/spotting was interrupted for at least 7 days during the month after they received a combined hormonal injection. We also evaluated bleeding at 21 days and 12 weeks after the injection.

STUDY DESIGN

We conducted a randomized, double-blind, placebo-controlled trial in 46 contraceptive implant users who presented with bothersome uterine bleeding/spotting. A single dose of a combination injectable contraceptive or placebo was administered intramuscularly at enrollment.

RESULTS

The proportions of participants whose uterine bleeding/spotting was interrupted for at least 7 days the month after they received a combined hormonal injection were higher in the combination injectable contraception group than in the placebo group (87% vs 48%, p = 0.005). Participants who reported that they were bleeding free at 21 days after treatment were 52% and 35% in the combination injectable contraception group and placebo group, respectively (p = 0.24). At 12 weeks posttreatment, 17% of participants in the combination injectable contraception group and 4% in the placebo group reported cessation of bleeding with no recurrence (p = 0.34). The median days until the first bleeding interruption was shorter in the combination injectable contraception group compared with the placebo group (1 [interquartile range, 1-2] vs 8 [interquartile range, 1-28], p = 0.007).

CONCLUSIONS

The combination injectable contraception interrupted bothersome uterine bleeding/spotting in contraceptive implant(s) users compared with placebo. However, this effect was limited only within the month when the treatment was administered.

IMPLICATIONS

Bothersome uterine bleeding/spotting is a common side effect leading to contraceptive implant(s) discontinuation. In implant users experiencing these symptoms with no estrogen contraindications, a combined injectable contraception appears to rapidly improve bleeding for the duration of injectable exposure (1 month).

Contraceptive Implant-Associated Bleeding in Adolescent/Young Adult Clinical Practice: Associated Factors, Management, and Rates of Discontinuation

PURPOSE

To identify factors associated with bothersome implant-associated uterine bleeding, and to evaluate the impact of bleeding management on implant discontinuation.

METHODS

We analyzed a quality improvement database of implant insertions (n = 825) at three adolescent/young adult programs and described individuals with and without reported bothersome bleeding. We utilized logistic regression to assess for factors associated with bleeding.

RESULTS

Implant recipient mean age was 18.9 ± 2.6 years, and 27% reported having subsequent bothersome uterine bleeding. Recipients had increased odds of reporting such bleeding if they had previously irregular menses (odds ratio [OR] = 1.36; 95% confidence interval [CI]: 1.11-1.68 irregular and infrequent, OR = 1.41; 95% CI: 1.07-1.86 irregular and frequent) or sought the implant for menstrual management purposes exclusively (OR = 1.67; 95% CI 1.42-1.96) or in combination with contraceptive need (OR 1.65; 95%: CI 1.57-1.72). Prior use of the progestin injection or implant was associated with lower odds of subsequent bleeding report (OR = 0.63; 95% CI: 0.54-0.73; OR = 0.54; 95% CI: 0.39-0.75, respectively). Medication management of bleeding was associated with the likelihood of implant discontinuation at 1 year compared to those with untreated bleeding (hazard ratio 1.98 times, 95% CI: 1.39-2.81). The implant was continued for 3 years in over 50% of recipients with ever-managed bothersome bleeding.

DISCUSSION

Individuals with historically irregular menses and those seeking the implant for menstrual management more often reported bothersome bleeding. Treating such bleeding with medication was associated with higher 1-year discontinuation rates, although many continued implant use for 3 years. Such findings may influence implant preinsertion counseling and/or postinsertion bleeding management.

General Approaches to Medical Management of Menstrual Suppression: ACOG Clinical Consensus No. 3

SUMMARY

The purpose of this document is to review currently available management options, general principles, and counseling approaches for reproductive-aged patients requesting menstrual suppression. It includes considerations for unique populations, including adolescents, patients with physical or cognitive disabilities or both, and those with limited access to health care. Gynecologists should be familiar with the use of hormonal therapy for menstrual suppression (including combined oral contraceptive pills, combined hormonal patches, vaginal rings, progestin-only pills, depot medroxyprogesterone acetate, the levonorgestrel-releasing intrauterine device, and the etonogestrel implant). Approaches to counseling should be individualized based on patient preferences and goals, average treatment effectiveness, and contraindications or risk factors for adverse events. Counseling regarding the choice of hormonal medication for menstrual suppression should be approached with the utmost respect for patient autonomy and be free of coercion. Complete amenorrhea may be difficult to achieve; thus, obstetrician-gynecologists and other clinicians should counsel patients and caregivers, if applicable, about realistic expectations.

The Etonogestrel Implant in Adolescents: Factors Associated With Removal for Bothersome Bleeding in the First Year After Insertion

STUDY OBJECTIVE

Temporizing measures such as hormonal pills can temporarily improve the side effect of breakthrough bleeding in individuals using the etonogestrel implant. The aims of this study were to determine demographic factors that are associated with bothersome bleeding and to evaluate the impact of prescribing temporizing measures on implant continuation.

DESIGN

Retrospective chart review.

SETTING

The research was conducted in an adolescent medicine primary and specialty care clinic, an adolescent family planning clinic, and a clinic that cares for parenting adolescents.

PARTICIPANTS

A chart review was conducted on 1200 patients aged 12-24 years who received the implant in 2016.

INTERVENTIONS AND MAIN OUTCOME MEASURES

The primary outcome measure was removal of the implant within the first year of use. We followed each patient for 1 year to determine rates of removal, reasons for removal, and temporizing measures prescribed for bleeding.

RESULTS

Younger age and lower body mass index were associated with reporting bothersome vaginal bleeding. Patients who were nulliparous or had bothersome bleeding were more likely to have the implant removed in the first year. Patients who received a temporizing measure for bleeding were more likely to retain the implant for 1 year than were those who did not receive one (67.1% vs 40%, P < .001).

CONCLUSIONS

Some patients are more likely to report concerns with bleeding or to have the implant removed in the first year after insertion. Prescribing temporizing measures to control bothersome vaginal bleeding may decrease rates of removal in the first year.

Contraception in Adolescents

Adolescents are at risk for unwanted pregnancy when they become sexually active, and contraception is an important part of mitigating this risk. Use of contraceptive methods, and long-acting reversible contraceptive methods such as implants and intrauterine devices in particular, has increased among adolescents. Although sexual activity has declined and contraceptive use has increased among adolescents in the United States in recent years, the unintended pregnancy rate remains high. All of the currently available contraceptive methods are safe and effective for adolescents to use; however, adolescents may have specific concerns about side effect profiles and unscheduled bleeding that should be addressed during contraceptive counseling. Healthcare providers should prioritize adolescents' needs and preferences when approaching contraceptive counseling, and also consider the unique access and confidentiality issues that adolescents face when accessing contraception.

Safety and Benefits of Contraceptives Implants: A Systematic Review

Progestin-only contraceptive implants provide long-acting, highly effective reversible contraception. We searched the medical publications in PubMed, CENTRAL, and EMBASE for relevant articles on hormonal implants published in English between 1990 and 2021. Levonorgestrel (LNG) 6-capsule subdermal implants represented the first effective system approved for reversible contraception. The etonogestrel (ENG) single rod dispositive has been widely employed in clinical practice, since it is a highly effective and safe contraceptive method. Abnormal menstrual bleeding is a common ENG side effect, representing the main reason for its premature discontinuation. Emerging evidence demonstrated that it is possible to extend the use of the ENG implant beyond the three-year period for which it is approved. The ENG implant could be an effective and discrete alternative to the IUD in young girls, such as post-partum/post-abortion. Implants should be inserted by trained skilled clinicians who previously provide adequate counselling about their contraceptive effect, benefits, and any possible adverse events. More studies are needed to validate the extended use of the ENG implant for up to 5 years.

Twelve-month Continuation of the Etonogestrel Implant in Adolescents With Polycystic Ovary Syndrome

STUDY OBJECTIVE

To identify why adolescents with polycystic ovary syndrome (PCOS) chose the etonogestrel (ENG) contraceptive implant, to determine the 12-month continuation rate, and to characterize factors related to discontinuation.

DESIGN, SETTING, AND PARTICIPANTS

Retrospective chart review of adolescents seen at a tertiary care children's hospital between July 1, 2008, and August 30, 2019, with PCOS diagnosis confirmed per National Institutes of Health criteria and ≥12-month ENG follow-up.

INTERVENTIONS AND MAIN OUTCOME MEASURES

Demographic characteristics, reasons for ENG insertion and removal, and information on other hormonal/contraceptive therapies were collected. Patients were categorized as ENG continuers (use ≥12 months) or discontinuers (removal at <12 months), and groups were compared.

RESULTS

A total of 96 patients met inclusion criteria (age 17.7 ± 2.2 years, body mass index 34.8 ± 8 kg/m²). Reasons for ENG were documented in 74% (51% contraception, 32% ease of use, 15% other, 13% estrogen avoidance). In all, 27% had never been sexually active, and 67% had had prior sexual activity. Treatments prior to ENG placement included 74% combined hormonal contraception, 20% medroxyprogesterone acetate withdrawal, and 17% depot medroxyprogesterone. A total of 77% continued ENG at 12 months. The main reasons for discontinuation were bleeding (41%), concern about weight gain (23%), and mood changes (18%). No preimplantation characteristics were independently predictive of continuation, although 100% of patients with type 2 diabetes (n = 11) continued. Patients who sought additional care, including telephone calls (41% vs 12%, P = .006) and clinic visits (64% vs 20%, P < .001) were more likely to discontinue.

CONCLUSIONS

The ENG implant was well tolerated in adolescents with PCOS and similar to published 12-month continuation rates.

Treatment of Unfavorable Bleeding Patterns in Contraceptive Implant Users: A Randomized Controlled Trial

OBJECTIVE

To evaluate whether a short course of tamoxifen decreases bothersome bleeding in etonogestrel contraceptive implant users.

METHODS

In a 90-day, double-blind randomized control trial, we enrolled etonogestrel implant users with frequent or prolonged bleeding or spotting. A sample size of 40 per group (N=80) was planned to compare 10 mg tamoxifen or placebo twice daily for 7 days after 3 consecutive days of bleeding or spotting no more than once per 30 days (maximum three treatments). Participants then entered a 90-day open-label study where all received tamoxifen if needed every 30 days (maximum three treatments). Participants used text messages to record daily bleeding patterns. Our primary outcome was the total number of consecutive amenorrhea days after the first treatment. Secondary outcomes included time to bleeding or spotting cessation and restart after first treatment, overall bleeding patterns, and satisfaction.

RESULTS

From January 2017 to November 2018, 112 women enrolled in the study; 88 (79%) completed 90 days, and 79 (71%) completed 180 days. Participant characteristics did not differ between groups; mean age 24, majority identified as white not Hispanic with at least some college education. After the first treatment, the tamoxifen group reported an average of 9.8 (95% CI 4.6-15.0) more consecutive days of amenorrhea and more total days of no bleeding (amenorrhea or spotting) in the first 90 days (median 73.5 [range 24-89] vs 68 [range 11-81], P=.001). The placebo group showed a similar treatment benefit after first active use of tamoxifen in the open-label phase. At the end of the randomized study (first 90 days), women who received tamoxifen reported higher satisfaction (median 62 mm [range 16-100]) than those treated with placebo (46 mm [range 0-100]; P=.023).

CONCLUSION

A short course of tamoxifen reduces problematic bleeding and improves satisfaction in users of etonogestrel implants.

Long-acting reversible contraception side effect management

PURPOSE OF REVIEW

Long-acting reversible contraception (LARC) is increasingly used by adolescents and young adults (AYAs). Subsequent to LARC insertion, AYAs are presenting to their primary care providers with LARC concerns. This article seeks to equip primary care clinicians with the tools necessary to assess and manage common LARC-associated side effects.

RECENT FINDINGS

Side effects are common with progestin-only LARC, and can precipitate early discontinuation of an otherwise effective, low-maintenance form of contraception. Abnormal uterine bleeding, pelvic pain, acne, and weight change are often cited as progestin-only LARC side effects, yet the causes are poorly understood despite extensive research. While most side effects improve with time, therapeutic interventions are available for patients with undesirable side effects that prefer medical management. Research emphasizes the importance of proper patient counseling and clinical follow-up.

SUMMARY

Counseling remains essential in the management of LARC-associated side effects. However, options are available to temporarily mitigate such side effects and increase LARC satisfaction. While these therapeutic options are prescribed based on expert opinion, such regimens remain inadequately studied in AYA populations.

Management of bleeding irregularities among etonogestrel implant users: Is combined oral contraceptives pills or nonsteroidal anti-inflammatory drugs the better option?

AIM

This study is to evaluate whether unacceptable bleeding among the etonogestrel implant user could be better alleviated using combined oral contraceptive pills (COCP) or nonsteroidal anti-inflammation drugs (NSAID).

METHODS

This is a prospective randomized study for evaluation of 84 etonogestrel implant (Implanon) users with prolonged or frequent bleeding. They were assigned to either receiving a COCP containing 20 mcg ethinyl estradiol/150 mg desogestrel for two continuous cycle or NSAID; mefenamic acid 500 mg TDS for 5 days, 21 days apart for two cycles. Bleeding pattern during the treatment was recorded and analyzed.

RESULTS

A total of 32 women (76.2%) in COCP group and 15 women (35.7%) in NSAID group stop bleeding within 7 days after the initiation of treatment which was statistically significant (P < 0.05). The mean duration of bleeding and spotting days in women treated with COCP was significantly lesser compared to NSAID group (7.29 ± 3.16 vs 10.57 ± 4.14 days (P < 0.05).

CONCLUSION

We conclude that COCP is more efficient compared to NSAID in managing bleeding irregularities among etonogestrel implant users.

Prevalence of early discontinuation and associated factors among a retrospective cohort of etonogestrel contraceptive implant users

Purpose: To characterise the frequency of and predictors of contraceptive implant discontinuation within 12 months of insertion in our clinical setting.Materials and methods: This retrospective cohort study included women receiving the etonogestrel contraceptive implant at our hospital between May 2007 and May 2012. We abstracted data from charts including implant removal date, bleeding complaints, reproductive and demographic characteristics, prior contraceptive use, tobacco use and implant insertion timing. Our primary outcome was implant discontinuation within 12 months following insertion. SAS 9.4 (SAS Institute Inc., Cary, NC, USA) was used to generate frequencies, bivariate analyses and multivariate logistic regression models.Results: Implant discontinuation was documented in 16% of implant users prior to 12 months (89/544). Women with documented bleeding complaints in the medical record were more likely to discontinue within 12 months (OR: 4.36, CI: 2.71, 7.00). No other demographic or clinical characteristics were associated with premature discontinuation. Having less than two prior pregnancies and tobacco use were associated with documented bleeding complaints.Conclusions: Discontinuation of the implant is associated with bleeding complaints. Women with lower parity and tobacco users may be more likely to experience bleeding or to find it intolerable.

Reproductive Health: Options, Strategies, and Empowerment of Women

Contraception is paramount to the overall health and longevity of women. Most women in the United States use birth control in their reproductive lifetimes. All options should be available and easily accessible to permit individualization and optimization of chosen methods. Current contraceptive methods available in the United States are reviewed. Emergency contraception, contraception in the postpartum period, and strategies to tailor methods to those affected by partner violence are also addressed. Tables and flow charts help providers and patients compare various contraceptive methods, optimize the start of a method, and identify resources for addressing safety in those with underlying medical conditions.

Post-abortion long-acting reversible contraception in a sample of Italian women: intrauterine device versus subdermal implant

Long-acting reversible contraceptives (LARC) represent an especially effective kind of post-abortion contraception. We aimed at assessing satisfaction, discontinuation, efficacy, and tolerability associated with either levonorgestrel intrauterine device (L-IUCD), the copper intrauterine device (C-IUCD) and implant (IMP) after termination of pregnancy (TOP). We recorded baseline data about the patients and performed phone surveys at 3, 6 and 12 months after insertion to assess the bleeding profile. Furthermore, women were inquired about possible adverse events, satisfaction, and discontinuation at 12 months after insertion. LARC continuers (>12 months after TOP) were divided into three groups: L-IUCD (n = 47), C-IUCD (n = 6) and IMP (n = 36). Satisfaction rates among L-IUCD users were higher than among IMP users (100% vs. 72.2%, p < .05). A higher, yet not significant, share of patients decided to withdraw contraception in IMP group (3.6% in IUCD group and 12.2% in IMP group). The bleeding profile was significantly more favorable among L-IUCD users than among IMP users. Finally, the reported rate of treatment-associated adverse events did not differ significantly among the groups. L-IUCD insertion after TOP is associated with higher satisfaction and lower discontinuation rates than IMP. Such pattern could be attributed to a more favorable bleeding profile.
