My 16 year old daughter has been prescribed tranexamic acid for extreme blood clots. They've told her to take 2 tablets, 3 times a day for a full 20 day course, however everywhere it says to NOT take them for more than 4 days. i was wondering if anyone else has been prescribed a similar course of tablets. Also on the information about these drugs, it says it will NOT stop bleeding all together but hers has stopped after 3 days on these drugs. Thank you.
