Anticoagulation risks
Patient education is essential for patients and/or carers to understand that they are on an oral anticoagulant, that their blood will take longer to clot and that they must be aware of signs of internal bleeding, which can be life threatening if not addressed in a timely manner.
Drug interactions
A broad range of medicines interact with warfarin. An important counselling point at the start of any new drug that may interact with warfarin is to encourage patients to notify their anticoagulation clinic and to review the date of their next INR test.
