Tranexamic acid
"I went through a good year or so of extremely heavy monthly menstruation.  One cycle, I happened to be in Paris and I was desperate.  Unable to do anything and feeling more or less bound to my room, I started researching.  Researching a cure for this heavy and debilitating bleeding.  I started my research and came across  a UK medical site that referenced Tranexamic Acid and people's personal reviews regarding this drug.  I walked into a pharmacy in Paris with my ipad in hand, with only a hope in mind.  They had it, I bought it and  took it.  Within less than 30 mins, my extreme bleeding had stopped and I got my life back!  I don't know how safe this medication is, but I have read nothing negative so far."
