i’ve been prescribed tranexamic acid for heavy periods but on the box it doesn’t say when to take them, just to take two three times a day. i’m assuming i only take them when i’m actually on my period, is that right? i’ve tried to call the pharmacy but i can’t get through. also do they make any real difference to the heaviness and length of periods? i’m currently having extremely heavy ten day long periods and i’m praying these actually do something!
