Take your warfarin once a day, at the same time, exactly as directed by your doctor. You could set yourself an alarm or a reminder on your mobile phone, or use another trigger such as the evening news on TV.
Keep track of your daily dose
Warfarin comes in different tablet strengths; each strength is a different colour. Your doctor may prescribe more than one tablet strength to make up your dose.
Because your dose may occasionally change, it’s a good idea to keep a record of the dose you are currently taking and the date you were prescribed it.
Stick to the same brand
Stick to the same brand of warfarin you are first prescribed - these medicines are not interchangeable.
The tablet colours differ between brands. Check the brand and tablet strength on the medicine label or packaging to ensure you’re taking the right brand and strength as prescribed by your doctor.
Know what to do if you forget a dose
If you forget to take a dose, only take the missed dose if you remember within 4 hours of the time you usually take it.
Don’t take the missed dose if you remember more than 4 hours after the time you normally take it. Take your next dose the next morning or evening at the usual time.
Don’t take a double dose at any time
Keep a note of any missed doses and tell your doctor.
Do not stop taking warfarin or change the dose unless advised to do so by your doctor. Your doctor will tell you how long you need to take warfarin for, and when you should stop taking it.
