Tinzaparin
Tinzaparin is a medication used to treat a certain type of blood clot. This "blood-thinning" drug works to prevent either the formation of clots or the growth of existing clots by binding to an enzyme in the body known as antithrombin III. It is given as a daily injection. The most commonly reported side effects include bleeding, chest pain, and nosebleeds.
Tinzaparin sodium (Innohep®) is a prescription medication approved to treat blood clots. It is an injectable anticoagulant, commonly known as a "blood thinner," although such medications do not actually "thin" the blood.
