tranexamic will not relieve the pain it will make the bleeding lighter. Thrombosis isnt listed as a side effect, I was given this drug for menhorragia following a termination. I had to take it for a couple of periods after as I flooding a bit.
As a teenager I used to get awful period pains, that would make me sweat. I took mefenamic acid, and that only worked in conjunction with sitting in the bath and sleeping. FOrtunately it doesnt happen anymore as I am allergic to NSAIDS now, is your daughter asthmatic? Is that why she wasnt presribed this, or maybe small for her age?
