What foods cause INR to increase?
Note: Most fruits, meats, starches, dairy products and sweets do not contain high amounts of vitamin K. Consuming large amounts of cranberry juice may increase warfarin levels (so your INR may be higher, and you may be at a higher risk for bleeding).
The foods that will potentially cause notable interactions with warfarin are mango, grapefruit, cranberry, and those with high vitamin K content such as certain green leafy vegetables, oils, multi-vitamins, herbal supplements, edible seaweed, avocado, and soymilk.
- Alcohol can also cause your body to make fewer platelets than normal. Warfarin also interferes with the clotting process, so drinking alcohol while you take warfarin can increase your risk of major bleeding. If you do decide to drink while taking warfarin, you should only drink occasionally.
- Involving your anticoagulation physician in your weight loss plan can be essential as diets that may seem popular in magazines may affect your INR as you transition to dieting aides. One such aid in weight loss that may or may not affect your INR level is a weight-loss or high-protein shake.
