Caring for someone taking warfarin
Caring for someone living with warfarin can be demanding, but you can help them take warfarin safely by knowing as much as you can about it.
Top warfarin tips for carers
- Find out why the person in your care is taking warfarin if you’re unsure.
- Anyone taking warfarin needs to have their INR tested as often as recommended. Never skip tests.
- Keep a record of their warfarin brand (Marevan or Coumadin), INR results and daily dose. Some people may need to take a different dose everyday or every other day. It is important to stick with the same brand of warfarin.
- Ask a doctor or pharmacist if you’re unsure what dose or tablet strength you need to give.
- Always tell all health professionals that someone in your care is taking warfarin.
- If you’ve missed a dose or mistakenly given a double dose, and you’re unsure what to do, ask a doctor or pharmacist.
- Keep a note of any missed or double doses and tell their doctor.
- Let their doctor know if the person you’re caring for has made any major changes to their lifestyle, including diet or alcohol intake.
- Seek medical advice if the person you’re caring for feels unwell, even if you don’t think it is related to the warfarin.
- Look after yourself too.
