Currently, several treatments for this alteration are described, however, the use of intrauterine devices with levonorgestrel (LNG-IUD), which in addition to acting as a contraceptive, significantly reduces abnormal uterine bleeding, therefore it takes a very important place in management of this disease. Objective: To investigate concepts about abnormal uterine bleeding and its management based on the role of the levonorgestrel-releasing intrauterine device. Methods: A systematic bibliographic review was carried out in the databases available on the internet such as: Scielo, Elsevier, Cochrane Library, Pubmed, Intramed, UptoDate, ScienceDirect. In addition, a meticulous review of the collected material was reviewed, aimed at the most relevant theoretical aspects. Results: 50 bibliographic sources were found, of which 34 relevant scientific articles were used and 16 were excluded because they did not meet the selection criteria. Discussion: The levonorgestrel-releasing device, in addition to its use as a contraceptive, has demonstrated validity and safety in the management of heavy menstrual bleeding, the benefit being greater than the risk in the patient. Conclusions: Abnormal uterine bleeding represents a very frequent problem in clinical practice, being vital to detect the cause in time to give an effective treatment. That is why the levonorgestrel-releasing device is an alternative for those patients with abundant flows.
