I'm 48 and had a PE 4/2/09. I entered this site looking to see if hair loss was a common side effect to the Warfarin I've been taking and, lo and behold, not only do I now have an explanation for my thinning hair but the acne, the joint pain, WEIGHT GAIN (UGH!) and gas / bloating. The powers that be have decided that the cause of the PE was my Yasmin birth control pills (a huge law suit going on for Bayer now - the producers of Yasmin, Yaz and one other one) and put me on the Warfarin for 6 months to life - we'll see about the 'to life' part on 10/02/09. I think regardless, I'm going with 'Tannabo' and trying the Nattokinase once I'm done with the Warfarin. Thank you for this 'enlightening' website and everyone's input!
