I am a 47 year old female. I had superficial blood clots in my left leg in Dec 05 and Nov 06. Developed a DVT in left leg and a superficial clot in right leg in June 07. Now taking 9 mg of warfarin (coumadin) a day. Suffering from extreme fatigue, heavy periods and I just discovered the hard way that warfarin makes you sensitive to the sun (got a severe sunburn on my face, forearms, hands and the top of my head, all places that I do not normally burn). Called the pharmacist and she said sun sensitivity is not a side effect. Went to several websites before I finally it upon one that did say that sun sensitivity is a side effect. My doctor did not tell me this and it is not a warning on the prescription label. Please be careful in the sun. Also, if you are a cranberry lover, I found several websites that said no cranberries in any form, juice, dried, herbal supplements, etc.
