Heparin

Alternative Names: Unfractionated Heparin, UFH

Heparin is a fast-acting blood thinner commonly used as the first treatment for pulmonary embolism (PE). It works by preventing existing clots from growing and stopping new ones from forming, giving the body time to naturally break down the clot. Heparin can be given through an IV for immediate effect or as an injection under the skin. Because its effects wear off quickly once stopped, it is often used in the hospital at the start of treatment before switching to an oral anticoagulant. The main risk is bleeding, so patients are closely monitored during therapy.

Review Summary

5.0

1 Reviews

Preferred by 1 Reviewers

Based on the review by Dr. Curbside, Heparin appears to be a highly effective treatment for Pulmonary Embolism, particularly in situations requiring immediate anticoagulation. It is especially recommended for patients with severe renal impairment, high bleeding risk, or when rapid reversal of anticoagulation is needed, with its short half-life and quick reversibility being key advantages.

Heparin is recommended in pulmonary embolism (PE) when immediate anticoagulation is required, including cases with confirmed PE or high clinical suspicion, even before diagnostic confirmation if the risk is high. Heparin is preferred in patients with severe renal impairment (CrCl <30 mL/min), high bleeding risk, clinical instability, or when rapid reversal is needed—for example, before procedures, during thrombolysis, or when aggressive interventions are planned. Its short half-life and ability to be quickly reversed make it especially valuable in these settings.
