When should I contact the Warfarin Care Clinic?

Medicine changes. If your medication changes for three days or longer (prescribed, or over the counter). This includes heparin (e.g. Clexane®) injection.
Hospital admission. If you’re admitted or discharged from hospital, please let us know.
Surgery or dental procedures. You’ll need to advise us of your pre-operative requirements. Ask your doctor for any special instructions relating to when you should recommence your warfarin and let us know at the Warfarin Care Management Service.
Holidays. You’ll need to tell us if you are going away on holidays so we can make the necessary arrangements for your testing.
No longer taking warfarin. If you stop taking this medication, our clinic needs to be advised.
