Treatment of Prolonged Menstrual Bleeding

Initial Evaluation and Treatment

The first-line approach is to rule out pregnancy, structural pathology, and systemic causes, then initiate NSAIDs for 5-7 days while considering hormonal therapy based on the underlying etiology, as recommended by the MMWR Recommendations and Reports 1, 2, 3

Initiate NSAIDs for 5-7 days during bleeding episodes, which reduce menstrual blood loss by 20-60%, according to the MMWR Recommendations and Reports 1, 2, 3
NSAIDs are effective regardless of whether bleeding is anovulatory or ovulatory, as stated in the MMWR Recommendations and Reports 3
Do not use aspirin, as it may paradoxically increase bleeding in some women, as noted in the MMWR Recommendations and Reports 2

For anovulatory bleeding, add combined oral contraceptives or estrogen for 10-20 days if the patient is using contraception and bleeding persists, as recommended by the MMWR Recommendations and Reports 1, 4, 5
For ovulatory bleeding, the levonorgestrel-releasing intrauterine system reduces menstrual blood loss by 71-95%, according to Praxis Medical Insights: Practical Summaries of Clinical Guidelines 6
Tranexamic acid reduces bleeding by 40-60%, but is expensive and contraindicated in women with active or history of thromboembolism, as noted in the MMWR Recommendations and Reports 2

For Cu-IUD users, initiate NSAIDs for 5-7 days, as recommended by the MMWR Recommendations and Reports 1, 4, 5
For LNG-IUD users, initiate NSAIDs for 5-7 days or hormonal treatment with COCs/estrogen 10-20 days, according to the MMWR Recommendations and Reports 1, 4, 5

Women on antiplatelet therapy may benefit from LNG-IUD, which reduces blood loss by 71-95%, as stated in Praxis Medical Insights: Practical Summaries of Clinical Guidelines 6
Persistent bleeding despite treatment requires re-evaluation for underlying pathology and consideration of alternative contraceptive methods, as recommended by the MMWR Recommendations and Reports 1, 4, 5, 6

Bleeding in the first 3-6 months of IUD use is common and generally not harmful, as noted in the MMWR Recommendations and Reports 2, 3

The Centers for Disease Control and Prevention recommends that women with copper IUDs who experience bleeding in the first 3-6 months can be treated with NSAIDs for 5-7 days 7
The Centers for Disease Control and Prevention suggests that women using contraceptive methods such as copper IUDs, who experience new-onset prolonged bleeding after months of use, should be evaluated for displacement, infection, pregnancy, or new uterine pathology, and treated with NSAIDs for 5-7 days 7
The Centers for Disease Control and Prevention recommends that women with prolonged menstrual bleeding can be treated with tranexamic acid, which reduces bleeding by 40-60%, but it is contraindicated in women with active thromboembolism or history of thrombosis 7

The American College of Obstetricians and Gynecologists recommends that perimenopausal women be carefully assessed for cardiovascular and thrombotic risk before using combined hormonal contraceptives, and that the levonorgestrel-releasing intrauterine system (LNG-IUS) remains the most effective option and can continue through menopause 7
