For my leukemia I take Ibrutinib which disrupts my platelets. So I bleed like I am on blood thinners. I also get nosebleeds easily and they are hard to control. If I am getting a significant procedure such as an extraction I stop the treatment for a few days ahead of time. I do not seem to need this for regular cleaning or a filling. I floss regularly and this actually seems to cut down on bleeding from a cleaning. I personally would not stop a blood thinner if it was for cardio vascular use. Based on what I have read, this seems to cause problems in some people. These problems are far worse than a little gum bleed.
