i been on warfarin since august 08 - its now end of feb 09, i have not noticed any serious side effects apart from blood in nose when wake up and snotter for the first time each day (excuse that term) . i have been sitting under newly installed lighjt at work and find it to be very hot on my head... everyone else says its not, but i cant stay there after ten minutes... its mildly uncomfortable.. and it got to thinking that maybe warfarin can effect the sun and the taking of the tablets, im on 6mg a day and i have heart problems, heart failure and cardiomyopathy, i would like to here from any one that has problems with sun...... and after how long hair loss and teeth problems came after taking it - im only 24 but worry about it thank you for your time i also get fatigue
