Management of Heavy Menstrual Bleeding in Perimenopausal Women

Immediate Assessment and First-Line Treatment

The American Academy of Family Physicians recommends endometrial evaluation is critical before initiating treatment in women over 35 years with irregular menses and perimenopausal bleeding pattern, to exclude endometrial hyperplasia or malignancy 3
Endometrial biopsy is indicated in women over 35 years with irregular menses, as it represents a perimenopausal bleeding pattern that requires exclusion of endometrial hyperplasia or malignancy 3
The American College of Obstetricians and Gynecologists recommends ruling out pregnancy with beta-hCG testing, despite age and irregular cycles 3
Checking TSH and prolactin levels is recommended, as thyroid dysfunction commonly causes irregular bleeding in this age group 3
The Centers for Disease Control and Prevention recommends NSAIDs as the first-line treatment for acute heavy bleeding, with ibuprofen 400 mg every 4-6 hours or mefenamic acid 500 mg three times daily for 5 days 1, 2, 4
Mefenamic acid 500 mg three times daily for 5 days has demonstrated significant reduction in bleeding, according to the American College of Obstetricians and Gynecologists 1, 2
NSAIDs work by inhibiting prostaglandin synthesis and reducing menstrual blood flow, with a reduction in menstrual blood loss by 20-60% 4

The American College of Obstetricians and Gynecologists recommends tranexamic acid as a second-line option, but it is contraindicated in women with cardiovascular disease risk factors, such as hypertension and hyperlipidemia 1, 4
A short course of combined oral contraceptives (10-20 days) may be considered if medically eligible, but may be contraindicated in women over 35 years with hypertension and hyperlipidemia 1, 2, 5
The levonorgestrel-releasing intrauterine system (LNG-IUD) is the most effective long-term medical treatment, reducing menstrual blood loss by 71-95% and often resulting in amenorrhea over time, according to the American College of Obstetricians and Gynecologists 1
