Tranexamic acid shows improvements in heavy menstrual bleeding

The antifibrinolytic drug tranexamic acid appears to significantly improve quality of life for young women who experience heavy menstrual bleeding, new research suggests.

Writing in the Journal of Pediatric & Adolescent Gynecology, Sarah H. O’Brien, MD, from Nationwide Children’s Hospital and the Ohio State University, both in Columbus, and her coauthors presented the results of an open-label efficacy study of the competitive plasminogen inhibitor in 25 adolescent girls aged 10-19 years who attended pediatric hematology clinics for evaluation or management of heavy menstrual bleeding. The study participants were instructed to take 1,300 mg of tranexamic acid (two tablets) three times a day for up to 5 days during their monthly menstruation for three cycles.

The study found a significant improvement in mean menstrual impact questionnaire (MIQ) scores, which improved from a mean of 3 at baseline to 1.91 (P less than .001). Two-thirds of patients reported at least a one-point improvement from baseline, and all reported that this was clinically meaningful. At baseline, 84% of patients reported heavy to very heavy blood loss, but this decreased to 23% after treatment with tranexamic acid (P less than .001).

The study population included ten individuals (40%) with bleeding disorders. However, the researchers did not see a significant difference in response between those with bleeding disorders and those without.

While the treatment did not significantly affect school attendance (only 24% reported that their heavy bleeding limited school attendance), researchers did see a significant improvement in limitations on physical activities and on social and leisure activities. Patients who reported at baseline that their menstrual bleeding significantly affected their social and leisure activities had an average score improvement of 1.74, a greater than or equal to one point improvement. Participants also reported significant improvements in their Pictorial Blood Assessment Chart scores, which dropped from an average of 255 to 155 (P less than .001).

The treatment did not show any significant effects on hemoglobin or ferritin. The most common adverse events were sinonasal symptoms, such as nasal congestion, headache, and sinus pain, but no thrombotic or ocular adverse events were seen.

Dr. O’Brien and her coauthors wrote that one limitation of their study was using the MIQ score as their primary endpoint as opposed to a more objective measure, such as change in measured blood loss.

“However, a major factor that motivates patients with heavy menstrual bleeding to seek medical care is the negative impact of heavy menstrual bleeding on daily life,” they wrote.

The study drug was supplied by Ferring pharmaceuticals, and the study was supported by the Hemostasis and Thrombosis Research Society. One author disclosed receiving the Joan Fellowship in Pediatric Hemostasis and Thrombosis at Nationwide Children’s Hospital; no other authors said they had relevant financial disclosures.
