Abstract

OBJECTIVE: Up to 60% of women discontinue using the levonorgestrel-releasing intrauterine system (LNG-IUS) within 5 years because of bleeding irregularities, pain and/or systemic progestogenic adverse effects. The aim of the study was to assess treatment options for bleeding irregularities in women using the 52 mg LNG-IUS.

METHODS: Database searches of Medline, Embase/Ovid and the Cochrane Library were carried out, and journals were searched by hand, for relevant studies published from database inception to March 2020. Inclusion criteria were randomised controlled trials (RCTs), prospective cohort studies and case-control studies of premenopausal women using the LNG-IUS and receiving medical treatment for bleeding irregularities. Screening, data extraction and quality assessment of retrieved articles were carried out independently by two pairs of reviewers. The primary outcome was the reduction of bleeding/spotting days.

RESULTS: Of the 3061 studies identified, eight met our inclusion criteria: six RCTs and two prospective cohort studies. The eight studies enrolled a total of 677 women who were treated with tamoxifen, mifepristone, ulipristal acetate, naproxen, oestradiol, mefenamic acid, tranexamic acid or the progesterone receptor modulator CDB 2914. The results of our analysis indicated that naproxen may be effective for the prophylactic treatment of bleeding immediately (<12 weeks) after LNG-IUS insertion (high level of evidence). Oestradiol may be effective in treating ongoing bleeding irregularities >6 months after insertion (low level of evidence).

CONCLUSION: Evidence for the medical treatment of (ongoing) bleeding irregularities during use of the LNG-IUS is lacking and more research is needed on the topic.
