Hi, I am a 47 year old woman and started Warfarin and Lovenox June 29th as a result of blood clots in my left leg from knee surgery. I was able to go off the Lovenox July 4th (Yay!) because my INR levels were above 2. I thought the Lovenox was the cause of the nausea I experienced, but apparently that is not the case. I keep telling the clinicians at the Anticoagulant Clinic about the nausea and their response is that they haven't heard of it as a side effect. Thank you all for posting to this website, there is some comfort in learning you are not alone with these strange side effects. I also experience dizziness and have difficulty finding words. I think I will switch from Warfarin to Coumadin to see if the side effects are less, though many of you have written about weight gain ~ yikes. For those of you bruising with Lovenox I was told if the needle is dry when it goes in there is much less bruising. And to everyone my thoughts and prayers are with you. Oh yeah, I also have nerve pain in the bottom of my left foot, the compression hose do help website is ******
