Food and Lifestyle Interactions Medicine Severity Page Link Substance Explanation Severity Meaning aspirinmoderateAlcohol (Ethanol)Ask your doctor before using aspirin together with ethanol (alcohol). Do not drink alcohol while taking aspirin. Alcohol can increase your risk of stomach bleeding caused by aspirin. Call your doctor at once if you have symptoms of bleeding in your stomach or intestines. This includes black, bloody, or tarry stools, or coughing up blood or vomit that looks like coffee grounds. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.Moderately clinically significant. Usually avoid combinations; use it only under special circumstances.warfarinmoderateFood/LifestyleNutrition and diet can affect your treatment with warfarin. Therefore, it is important to keep your vitamin supplement and food intake steady throughout treatment. Vitamin K helps your blood clot, so eating more vitamin K can make warfarin less effective. You do not need to avoid foods with vitamin K, but you should keep your intake steady from day to day. Foods high in vitamin K include liver, broccoli, Brussels sprouts, cabbage, collard greens, endive, kale, lettuce, mustard greens, parsley, soybeans, spinach, Swiss chard, turnip greens, watercress, and other green leafy vegetables. Foods with moderate vitamin K levels include asparagus, avocados, dill pickles, green peas, green tea, canola oil, margarine, mayonnaise, olive oil, and soybean oil. Some foods that do not contain vitamin K may still affect warfarin. There have been reports of increased bleeding in patients who consumed large amounts of cranberry juice, grapefruit, grapefruit juice, or pomegranate juice. You should avoid or limit their consumption while you are receiving warfarin. If you take warfarin you should avoid large amounts or chronic consumption of alcohol. Alcohol may increase your risk of bleeding or clotting depending on the amount and pattern of alcohol consumption, as well as your liver function and disease state. If you get warfarin through a feeding tube, your doctor may adjust your feeding times around your medicine. Call your doctor right away if you notice unusual bruising, blood in your urine or stool, black or tarry stools, coughing up blood, vomiting blood, swelling or pain in your arms or legs, chest pain, trouble breathing, or sudden weakness or numbness. Talk to your doctor if you have questions about foods, substances or alcohol that may interact with warfarin. It is important to tell your doctor about all medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.Moderately clinically significant. Usually avoid combinations; use it only under special circumstances.warfarinmoderatemultivitamins with mineralsRarely, vitamin supplements containing vitamin K may reduce the effectiveness of warfarin. This may be more likely to occur in individuals who have low levels of vitamin K in their blood. Before using any vitamin supplement, you should check the label to make sure it does not contain vitamin K. If it does, let your doctor know before you start using it. You may need more frequent monitoring of your INR after starting the supplement or whenever it is discontinued, and appropriate adjustments made in your dosage if necessary. It is important to tell your doctor about all other medications you use, including other nutritional supplements and herbs. Do not stop using any medications without first talking to your doctor.Moderately clinically significant. Usually avoid combinations; use it only under special circumstances.warfarinmoderateNicotineAs you stop smoking during treatment with nicotine, your dosage requirement of warfarin may need to be changed. Talk to your doctor if you have any questions or concerns. Your doctor may be able to prescribe alternatives that do not interact, or you may need a dose adjustment or more frequent monitoring by your doctor to safely use both medications. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.Moderately clinically significant. Usually avoid combinations; use it only under special circumstances.aspirinminorCaffeineOne study has reported that coadministration of caffeine and aspirin lead to a 25% increase in the rate of appearance and 17% increase in maximum concentration of salicylate in the plasma. A significantly higher area under the plasma concentration time curve of salicylate was also reported when both drugs were administered together. The exact mechanism of this interaction has not been specified. Physicians and patients should be aware that coadministration of aspirin and caffeine may lead to higher salicylate levels faster. References (1) Yoovathaworn KC, Sriwatanakul K, Thithapandha A (1986) "Influence of caffeine on aspirin pharmacokinetics." Eur J Drug Metab Pharmacokinet , 11, p. 71-6Minimally clinically significant. Minimize risk; assess risk and consider an alternative drug, take steps to circumvent the interaction risk and/or institute a monitoring plan.
