I no longer take Mefenamic Acid, as when I went on the contreceptive pill my serious menstral pains seemed to subside completely.
But when I was taking Mefenamic Acid my doctor prescribed me to take it 3 times a day, orally, every day that I was on my period. And it worked very well for me in the couple years that I used it. Hope this helps!
