In the last thirty days or so, upon the advice of my dialysis nurse, I have started to use Heparin as an additive to the dialysis fluid I employ at night. Heparin is a go-to solution to drain alarms on the Liberty Cycler. In the next two blogs, I intend first, in this blog, to present findings on the drug Heparin itself. In the following blog tomorrow, I will present findings on its use as relates to dialysis.
To ascertain a meaningful background on the drug Heparin itself, I turned to my AI assistant Poe and entered the prompt in blue below, followed by the comprehensive overview.

Title: Heparin: A Lifesaving Anticoagulant Derived from Swine
Introduction:
In the world of medicine, heparin plays a vital role as an anticoagulant. It is widely used to prevent and treat blood clots, making it an essential medication for various medical conditions. Derived from animal sources, primarily swine, heparin has a long history of use and has saved countless lives. In this blog post, we will explore the origins of heparin, its production process, who should and should not use it, and important safety precautions.
The Origin and Production of Heparin:
Heparin is a naturally occurring substance found in the bodies of mammals, including humans. However, it is primarily extracted from the mucous membranes of swine (pigs) and, to a lesser extent, from the tissues of cattle and sheep. The specific biological function of heparin in these animals is still not fully understood, but it is believed to play a role in preventing excessive blood clotting.
The production of heparin involves a complex and highly regulated process. After the animals are slaughtered, their intestinal tissues are collected and processed to extract heparin. The extracted material undergoes purification and further processing in specialized facilities to ensure its safety and efficacy. Stringent quality control measures are implemented throughout the manufacturing process to maintain high standards of purity and safety.
Who Should Use Heparin:
Heparin is commonly used in the prevention and treatment of blood clots in various medical settings. It is often prescribed to patients who are at risk of deep vein thrombosis (DVT), pulmonary embolism (PE), or who have undergone certain surgical procedures that carry a heightened risk of clot formation.
Heparin is also used in the management of acute coronary syndrome, a condition characterized by reduced blood flow to the heart. Additionally, it plays a crucial role in certain medical procedures, such as kidney dialysis and heart bypass surgery, where blood clotting must be prevented.
Who Should Not Use Heparin:
While heparin is generally safe and effective, there are individuals who should exercise caution or avoid its use altogether. People with a history of heparin-induced thrombocytopenia (HIT), a rare condition characterized by decreased platelet counts and an increased risk of clotting, should not be administered heparin due to the potential for severe complications.
Patients with uncontrolled bleeding, severe liver disease, or a known hypersensitivity to heparin should also avoid its use. It is crucial for healthcare professionals to thoroughly evaluate a patient’s medical history, existing conditions, and allergies before initiating heparin therapy.
Safety Precautions and Considerations:
When using heparin, healthcare providers must closely monitor patients to ensure appropriate dosing and optimal therapeutic effect. Regular blood tests, such as activated partial thromboplastin time (aPTT) or anti-Xa activity, are performed to assess the patient’s response to treatment and adjust the dosage if necessary.
It is important to note that heparin carries a risk of bleeding, which can range from mild to severe. Patients receiving heparin should be educated about the signs of bleeding, such as unusual bruising, prolonged bleeding from cuts, or blood in the urine or stool. If any of these symptoms occur, immediate medical attention should be sought.
Conclusion:
Heparin, derived from swine and other animal sources, has been a lifesaving medication for many patients at risk of blood clots. Its production involves a rigorous process to ensure purity and safety. While heparin is widely used and generally safe, it is important for healthcare providers to carefully evaluate patients’ medical history and monitor them closely for potential complications. By adhering to safety precautions and guidelines, heparin plays a crucial role in preventing and treating life-threatening blood clots.
Fresenius provides heparin in a case of 25 30 mL bottles, each of which is two doses, given my current dialysis prescription. Heparin is distributed by Hospira out of Lake Forest, IL 60045.
