What is Heparin Used For?
Heparin is a very important medicine. It helps prevent and treat blood clots. Blood clots can be dangerous if they form in the wrong places, like in your legs or lungs. Heparin makes your blood thinner, so it doesn't clot as easily.
This medicine is often used in hospitals for people who have had surgery, or who are at risk of getting blood clots. It helps keep their blood flowing smoothly.
How Was Heparin Discovered?
Heparin was first found in 1916 by Jay McLean, a medical student at Johns Hopkins University. He was working with his professor, William Henry Howell. They first extracted, or took out, heparin from the guts of animals like turkeys, salmon, and even mice.
The discovery of heparin was a big step forward in medicine. It gave doctors a powerful tool to help people with blood clotting problems.
Why is Heparin Important?
Heparin is so important that the World Health Organization (WHO) has put it on their List of Essential Medicines. This list includes the most important medicines needed in a basic healthcare system. Being on this list shows how valuable and successful heparin is in treating serious health conditions around the world.
Using Heparin Safely
Like all medicines, heparin needs to be used carefully. Doctors decide the right amount for each person. Taking too much heparin can cause problems, such as making it harder for cuts and wounds to heal. This is because it affects tiny parts of your blood called platelets, which are important for stopping bleeding and healing.
Doctors always make sure to give the correct dose to keep patients safe and healthy.
