Warfarin: If taking warfarin, obtain the relevant INR plan; INR does not measure all antithrombotic medicines.
Prophylaxis: Endocarditis prophylaxis for qualifying anatomy and procedures: amoxicillin 50 mg/kg orally, maximum 2 g, as a single dose 30–60 minutes before; assess allergy and alternatives as below
Prevention: Prioritize sustained plaque control and prevention: daily oral activities can produce bacteremia, so an isolated prophylactic antibiotic dose does not replace oral health maintenance
Anesthesia: Sedation and GA in a hospital setting with cardiac anesthesia for unrepaired or complex disease
Antithrombotic changes: do not stop or reduce prescribed anticoagulants or antiplatelets independently. Most routine dental procedures can use local hemostasis; higher bleeding risk or extensive surgery needs a prescriber-directed plan. ADA: medication management.
