my ex-husband has been taking first, lovenox injections and then was switched to heprin. After coming home from a nursing facility, no order was written for a blood thinner. It has been 4 days without it, and I'm concerned. He has a pic line that I flush with saline but no heprin flush to follow, and he also has no heprin injections. I have been unable to reach the on call nurse for the Home Health Care.
