Purpose
Menorrhagia (heavy menstrual bleeding or heavy bleeding during your "period") is a common problem in adolescents. It results in major quality of life issues such as loss of school days, and reduction in social activities and travel. Menorrhagia also occurs in adult women. There is some data regarding menorrhagia in adult women but there has been limited research in this area in adolescents. As a result, most of the treatments for adolescents with menorrhagia are based on experience in adult women.
This study is specifically designed to help gather information about how to better diagnose and treat menorrhagia in adolescent girls. This study will compare treatment with Tranexamic Acid (TA) to treatment with combined oral contraceptives. Both of these treatments are currently used to treat menorrhagia in adult women.
Tranexamic acid is approved for such treatment in adult women but not in adolescent women. Oral TA, not available previously in the U.S., was approved by the United States Food and Drug Administration in November 2009 for management of heavy menstrual bleeding in women. There is currently no approved indication for the use of tranexamic acid in patients less than 18 years of age. The use of oral contraceptives in adolescent women is considered standard of care.
The main purpose of this study is to find out if oral tranexamic acid is as good as or better than combined oral contraceptives in reducing menstrual blood loss in adolescents with menorrhagia.
The second purpose is to find out if oral tranexamic acid is as good as or better than combined oral contraceptives in improving quality of life in adolescents with menorrhagia.

Detailed Description:
Subjects will be randomized to one of two groups (group A or B).
Group A will receive oral tranexamic acid at 1300 mg (two 650mg tablets), three times each day on days 1 to 5 of menstrual cycle for 3 cycles.
Group B will receive combined oral contraceptive pills (OCP) with 3 weeks of hormonal pills and 1 week of placebo for 3 cycles.
After 3 cycles of therapy, both groups will have one cycle without any therapy. Then, the groups will cross over. Group A, who first received TA, will then receive OCP. Group B, who first received OCP, will then receive TA.
All subjects will receive both tranexamic acid and oral contraceptive pills.
There will be a total of 3 study-associated visits per patient: 1 at baseline and 2 at the end of 3 cycles on each medication. These visits are considered within standard of care, as subjects with menorrhagia have frequent monitoring until the effectiveness of the treatment is determined.
At the study visits the following will be done:
- Assessment of the last menstrual period (amount of blood lost) and the number of days the period lasted
- Quality of Life evaluation - you will complete a standardized quality of life questionnaire
- Detailed history and physical examination to evaluate for drug side effects and to look for signs of blood clots. If the doctor thinks the subject may have a blood clot, they may need an ultrasound to look for a blood clot.
- Blood will be drawn for a complete blood count test. This is a standard test that would be done even if you were not on this study.
