Long Term Results / Before & After Of Tranexamic Acid 650 MG Tablet. Especially on Black Skin? Dark Pigmentation rebound when off it? Health problem or risks? Etc.?

My dermatologist just prescribed me Tranexamic Acid 650 MG Tablet. Does any one have any results of using Tranexamic Acid 650 MG Tablet Short term (2-3 months) and the long term effects it has on skin? Does the melasma/ dark area rebound? Does it rebound as strong? Does it rebound but not as strong? Has anyone not used it for a year? How much rebound did it have? Did you have blood clots or health problems?
