Warfarin is taken as a once a day medicine and doses are dependent on the persons needs to balance clot prevention and bleeding risk. Warfarin can sometimes be referred to as a ‘blood thinner’ however, it doesn’t actually make the blood thinner, it just interferes with the clotting process and therefore stops clots forming in the veins.
When starting warfarin treatment, it is very important that people are given information about the need for regular blood tests to check their International Normalised Ration (INR) level. Some people stabilise on warfarin very quickly, whilst others may take longer and need frequent dose adjustments.
Warfarin levels can be affected by diet, alcohol and other medications, over the counter drugs and herbal and homeopathic remedies. Your healthcare professional should provide you with information about how to manage your treatment.
