hI , I am 49 years old single. Went to OB-Gyne yesterday and she prescribed me the Althea because of continues menstrual flow. My Menstrual period started last July 15 , 3 days for strong period. after that the stain continues till July 27 @ night. In the morning of July 28, I found a fresh blood again in my underwear. And this is the reason why I went to OB-gyne. She prescribes tranexamic acid 500mg for 3 days and althea for 5 days only. If the Tranexamic can help in controlling menstrual flow, then What is the function then of althea?
