Pause may be needed. Your doctor should be monitoring the level of blood thinning by measuring your inr. If your INR is above 3, a tooth extraction can lead to a great deal of bleeding. Before your procedure, your doctor may want to withhold your warfarin (coumadin) until your INR falls to a safer level, then restart immediately after the procedure.
Yes. But stop Coumadin (warfarin) 1 week before the procedure.
It delays clotting. Coumadin (warfarin) is used to prevent clotting in the blood vessels. It will result in prolonged bleeding which is difficult to stop. Most physicians in my experience have the patient stop the Coumadin (warfarin) for a few days before the extraction and resume it the next day or two after the extraction.
Decreased healing. Patients are on Coumadin (warfarin) to keep from having a stroke. If they are well regulated by their physician then I feel it is better to stay on the coumadin, (warfarin) deal with a little extra bleeding and not risk having a stroke.
Absolutely. Increased risk of bleeding. Can be life threatening.
YES. Coumadin (warfarin) retards clotting in stroke and cardiac patients. Usually a surgeon would like the patient to be off for three days, and an inr test taken to show that the risk of a significant bleed does not occur.
Should delay. To avoid unnecessary bleeding also need to know why one is taking the coumadin if for heart valve replacement, one may need antibiotic coverage see aha ada guidelines.
