These procedures include vaccinations and routine dental cleanings. If you're going to have surgery, discuss what dosing changes might be necessary at least 10 days before the procedure. Your doctor may decrease your dose of warfarin or discontinue warfarin altogether before the procedure. Avoid situations that increase your risk of injury. Things to avoid include contact sports or activities that could result in head injury. Make sure you tell your doctor if you are unsteady while walking or have a history of falling. Consider wearing a bracelet or carrying a card that identifies that you take warfarin. This can be useful if emergency medical personnel need to know what medications you take. Consider a warfarin sensitivity test. About a third of the people who take warfarin are at a higher risk of bleeding because their genes make them more sensitive to warfarin.

The test can tell if you have the genes that can increase your risk of bleeding. What drugs and supplements can interact with warfarin?
