What happens when you start Warfarin

• You will be given a booklet called Anticoagulation Therapy Record that provides an ongoing record of your blood tests and warfarin dosage
• Remember to bring the booklet with you every time you visit Anticogulation Clinic
  
• Warfarin dose is adjusted according to your desired International Normalised Ration (INR) that measures the effectiveness of warfarin and its bleeding risk
• Your desired INR range is: _____________________
• Blood tests may be required more frequently to determine the appropriate warfarin dose
• Your dose may change after each visit depending on your INR result. Your doctor or pharmacist will inform you any dose changes
• Inform your doctor or pharmacist of any illnesses, hospitalisation, changes in medication(s) or lifestyle at your next appointment
• Inform other healthcare professionals (doctors, dentist, pharmacist) whom you are seeing for other condition(s) that you are on warfarin
  

• Take it as soon as you remember if it is within 8 hours of your usual time to take warfarin
• If it is after 8 hours, skip the dose for that day
• Just take your warfarin dose at the usual time the next day
• DO NOT take double doses, unless your doctor tells you to, as this can cause excessive bleeding
• Record the dates on which you missed your dose(s). Inform your doctor at your next appointment
