What is Heparin Lock (heparin flush)? Heparin is an anticoagulant (blood thinner) that prevents the formation of blood clots. Heparin flush is used to flush (clean out) an intravenous (IV) catheter, which helps prevent blockage in the tube after you have received an IV infusion. Heparin flush should not be used to treat or prevent blood clots in the body. A separate heparin product is available to use for this purpose.
