Amoxicillin-related postextraction bleeding in an anticoagulated patient with tranexamic acid rinses.
This report describes a patient who had significant postoperative bleeding 4 days after undergoing surgery while using a tranexamic acid (4.8%) mouth rinse protocol for local control of hemostatis. Patients undergoing dentoalveolar surgery who are receiving chronic oral anticoagulants are treated with a tranexamic acid mouth rinse at our hospital. No systemic modification of their coagulation status is attempted. The postoperative bleeding problem that developed was determined to be caused by an antibiotic-induced vitamin K deficiency rather than a failure of the tranexamic acid protocol.
