Warfarin is a drug which can prevent life threatening conditions. However, it can be dangerous if people taking it are not monitored regularly and advised which dose to take. Recent changes have been made to the way we prescribe it.
When a patient requests a prescription for anti-coagulation, the doctor must check that the necessary monitoring has been carried out. We can no longer prescribe a anti-coagulation drug “as directed” and the specific dose must be stated on the prescription.
