Risk factors for people taking warfarin


Alcohol affects INR values

Large quantities of alcohol have a coagulative effect. The chronic consumption of alcohol, however, has a reverse effect, i.e. blood coagulation is reduced. Alcohol should be taken in moderation. Always ask your doctor for further advice.

Avoid irregular consumption of vegetables and other foods high in vitamin K: the following foods are amongst those high in Vitamin K and should be eaten with care (avoid eating a lot one day and nothing the next):

  • Fish, liver, spinach, cabbage, cauliflower, broccoli, Brussels sprouts, kale.

Herbal products (such as herbal teas) may also affect your INR. Similarily, vitamins and minerals, homeopathic medicines, traditional medicines (like Chinese medicines), probiotics and nutritional supplements such as amino acids and essential fatty acids,  can also impact your INR.

For greater convenience and INR control, discuss self-monitoring of your warfarin with your doctor using the CoaguChek® INRange meter.
