Heparin and coumadin are two different drugs that are used in preventing clotting. These drugs work in such a way that they make the consistent flow of blood thin and thus run more freely inside the vein. Coumadin, which can also be referred to as warfarin, is available in tablet form and vial form. They can be administered intravenously or through oral means.
On the other hand, heparin is available in only intravenous form. The side effects of heparin include redness, swelling, and pain. It can also be irritating when taken intravenously—meanwhile, gastrointestinal upset like bloating, vomiting, stomach ache, and feeling of nausea. You can also take Coumadin to prevent strokes and heart attacks, and it has more pressing reactions when you take it.
The reactions include diarrhea, chills, low-grade fever, numbness, weakness, skin discoloration, headache, and more. However, taking heparin also has its own effects, such as easy bruising, blood in the urine, blood stool, epistaxis, or nose bleeding.
