Warfarin, aspirin and Plavix are the most widely used medications for blood thinning, according to Heart MD Institute. Blood thinners are usually prescribed to prevent clots from strokes.
Anticoagulants or blood thinners keep platelets from forming clusters and blocking arteries. Aspirin thins the blood and prevents heart disease, while warfarin lowers the amount of vitamin K that the body produces. These medications are prescribed after major surgeries or heart conditions. Those taking these medications should be careful not to get cut. Bruising also occurs easily while on a blood-thinning regimen. A doctor should schedule regular testing to check the clotting of the blood.
