Tranexamic acid for heavy periods

Has anybody been prescribed Tranexamic acid for heavy bleeding? My friend works in a pharmacy and also has PCOS and has been prescribed this for her heavy bleeding. I have low ferritin but my periods aren’t that heavy, although I am passing bloods clods the first and second day, I’d say smallish about the same size as regular peas, sometimes the size of marrowfat peas. She had recommended me going onto Tranexamic acid to help with the bleeding as this could have been the cause of my ferritin dropping about 40% in the last month and a half. Just wanted to ask if anybody is on it and how it made them feel? Any side effects etc?
