I took Lovenox 5 years ago when I got 2 blood clots in my leg after a surgery. I also was on Coumadin. As a precaution before banding, I was given a dose of Lovenox, and then 1 the next day. Lovenox will thin the blood, but I have been told it is not as dangerous as high molecular weight heparin (what you would get through an IV) Lovenox is a low molecular weight that is given in subcuatenous fat. I will tell you that I was on 2 shots a day for almost a month. One little secret I learned, because it can burn when going in (you do not even feel the tiny needle) is to very slowly depress plunger so you do not have all the meds going in at once and burning. I just sat there for about 30 seconds or so and kept pressing on plunger until all was in. This did not hurt at all. Do not rub after!! GOod luck...
