Heparin, also known as unfractionated heparin (UFH), is a medication and naturally occurring glycosaminoglycan. [3] [4] Heparin is a blood anticoagulant that increases the activity of antithrombin. [5] It is used in the treatment of heart attacks and unstable angina. [3] It can be given intravenously or by injection under the skin. [3]
Apart from using unfractionated heparin instead, it may be possible to reduce the dose and/or monitor the anti-Xa activity to guide treatment. [3] The most common side effects include bleeding, which could be severe or even fatal, allergic reactions, injection site reactions, and increases in liver enzyme tests, usually without symptoms.

Heparin is the most widely used intravenous clinical anticoagulant worldwide. [82] Heparin is a naturally occurring glycosaminoglycan. There are three major categories of heparin: unfractionated heparin (UFH), low molecular weight heparin (LMWH), and ultra-low-molecular weight heparin (ULMWH). [83]
Antithrombin concentrates have been used, though with risk of bleeding at large doses of unfractionated heparin. Low molecular weight heparin at full weight based dosing is effective; however, measurements of peak anti-Xa levels may not reflect anticoagulant effect.
Heparin may be used for both prevention and the treatment of thrombosis. It exists in two main forms: an "unfractionated" form that can be injected under the skin (subcutaneously) or through an intravenous infusion, and a "low molecular weight" form that is generally given subcutaneously.
A 2021 review found that low molecular weight heparin (LMWH) was superior to unfractionated heparin in the initial treatment of venous thromboembolism for people with cancer. [3] There are medication-based interventions and non-medication-based interventions. [4]

Unfractioned heparin (UHF) is the most commonly used anticoagulant in hemodialysis, as it is generally well tolerated and can be quickly reversed with protamine sulfate. Low-molecular weight heparin (LMWH) is however, becoming increasingly popular and is now the norm in western Europe. [ 4 ]
