Hello! After having thoroughly gone through your discussion, I would like to suggest you
1) You need to continue the antihypertensive medications regularly.
2) But I would suggest you to stop the prednisone
as well as the cholesterol
lowering agents in view of prolonged nasal bleeding
3) Vitamin C would be better to be taken instead of tranexamic acid
& ethamsylate is also a good alternative.
4) You are requested to have consultation with an eminent physician in view of availability of more advanced medications, & further investigations.
Thanks & take care of yourselves!
