Do not miss a dose. If you do, do not double up your dose. Keep track of missed doses.
Check your INR (International Normalized Ratio) as scheduled. This number tells you how thick or thin your blood is. Your physician will adjust your dose as necessary. This is why it's important to keep track of any missed doses.
Keep your dietary vitamin K intake consistent day to day. Warfarin works on vitamin K to prevent clots. Vitamin K is found primarily in green leafy vegetables. Ask your physician or pharmacist for a list of vitamin K containing foods.
Warfarin interacts with many things. Consult with your physician or pharmacy when making changes to vitamins, OTC items, diet, and other medications. Any changes made, let your physician know.
Take warfarin with a full glass of water at the same time every day.
Store your medication away from heat, light, and moisture.
Make sure your physician knows of any upcoming surgeries, procedures, and especially dental work. (Let all of your providers know you take warfarin)
Carry an ID card that states you take warfarin.
If you take warfarin, it is for an important reason. Education is needed for friends and family also.
Read your patient information leaflet that comes with your medication. It tells you a lot!
