Heparin is an anticoagulant (blood thinner) that prevents the formation of blood clots.
Heparin is used to treat and prevent blood clots caused by certain medical conditions or medical procedures. It is also used before surgery to reduce the risk of blood clots.
Do not use heparin injection to flush (clean out) an intravenous (IV) catheter. A separate product is available to use as catheter lock flush. Using the wrong type of heparin to flush a catheter can result in fatal bleeding.
