Difference between Heparin and Coumadin

There are a few different types of medications used to help prevent blood clots. Heparin and Coumadin are two of the most common. They both work in different ways to help keep your blood flowing smoothly, but there are some key differences between them. Let’s take a closer look at how these two drugs work and how they differ from each other.

What is Heparin?

Heparin is a medication that is used to prevent blood clots from forming. It works by binding to a protein in the blood, which prevents clotting factors from working properly. Heparin is given either by injection or intravenously. The usual dose is 80 units per kilogram of body weight per day. Heparin can cause side effects, such as bleeding and low blood pressure. It can also interact with other medications, so it is important to tell your doctor about all the medications you are taking. Heparin is a life-saving medication that is used in many different medical settings, including surgery and cancer treatment.

What is Coumadin?

Coumadin is an anticoagulant medication that is used to prevent blood clots from forming. It works by inhibiting the clotting factor in the blood, known as vitamin K. Coumadin is prescribed for people who are at risk for developing blood clots, such as those with heart disease or those who have had a stroke. It is also sometimes given to people who are undergoing surgery. Coumadin can cause side effects, such as bleeding and bruising. It is important to take Coumadin exactly as prescribed by a doctor in order to minimize the risk of side effects.

Difference between Heparin and Coumadin

Heparin and Coumadin are two commonly used anticoagulants or blood thinners. Heparin is a natural substance that is produced in the body and is also available in synthetic form. Coumadin is a synthetic drug. Both drugs work by preventing the clotting of blood.

  • Heparin is typically used to treat acute conditions, such as heart attacks and strokes. It can also be used to prevent the formation of clots in patients who are at high risk for clottings, such as those undergoing surgery or those with certain medical conditions. Coumadin, on the other hand, is usually prescribed for long-term prevention of clotting, such as in patients with artificial heart valves or who have had previous strokes.
  • The major difference between the two drugs is that heparin works quickly and its effects wear off relatively soon after it is discontinued, while coumadin takes longer to work but its effects last for a longer period of time after it is stopped.
  • Both drugs carry a risk of bleeding, which may be increased when they are used together. As a result, it is important that patients taking either drug be closely monitored by their healthcare provider.


The main difference between Heparin and Coumadin is that Heparin is a natural product while Coumadin is a synthetic product. Both drugs are anticoagulants, which means they prevent blood from clotting. They both have their place in the medical community, but doctors will often prescribe one over the other depending on the patient’s individual needs.
