Heparin - Medical Glossary

Understanding Heparin?

Heparin works by blocking certain clotting factors in the blood, preventing clots from forming or growing larger. It doesn't dissolve existing clots but stops them from getting worse. It’s often used short-term and closely monitored due to its potency and risk of bleeding.

Symptoms and Signs That May Need Heparin Use?

Doctors may prescribe heparin for individuals showing signs of clotting problems, such as swelling in the legs, chest pain, shortness of breath, or after surgeries that increase clot risk. It is also used in patients with irregular heartbeats or mechanical heart valves.

Causes and Risk Factors for Heparin Use?

People at higher risk of blood clots due to recent surgeries, immobility, certain heart conditions, or inherited clotting disorders may be prescribed heparin. It’s also used in dialysis and certain lab tests to prevent blood clotting during procedures.

Treatment Considerations and Monitoring for Heparin?

Heparin is usually given via injection into a vein or under the skin. Its effects are closely monitored with blood tests like the aPTT (activated partial thromboplastin time). Side effects include bruising, bleeding, or rarely a condition called heparin-induced thrombocytopenia (HIT).

When to Seek Medical Help While on Heparin?

Contact a doctor immediately if you notice unusual bleeding (like in urine, gums, or stool), unexplained bruises, severe headaches, or dizziness. These may indicate bleeding complications. Always inform healthcare providers before any procedures if you are on heparin.
