Interactions between your drugs
Applies to: acetaminophen / dextromethorphan / guaifenesin / pseudoephedrine and dicumarol
Using acetaminophen together with dicumarol is generally considered safe. However, the risk for bleeding may increase if higher dosages of acetaminophen (more than 1300 mg/day) are used for more than a few days at a time, especially in individuals who are elderly, consume alcohol regularly, or have poor nutrition. 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 of your INR to safely use both medications. Many over-the-counter and prescription drug products used for the treatment of cough and cold, flu, pain, fever, arthritis, or headache may contain acetaminophen. To avoid inadvertently taking too much acetaminophen, you should check the ingredients of all the medications you take or intend to take. Consult a healthcare professional if you are not sure if a drug product contains acetaminophen, or if you need help figuring out what products are safe for you to use. You should seek immediate medical attention if you experience any unusual bleeding or bruising, or have other signs and symptoms of bleeding such as dizziness; lightheadedness; red or black, tarry stools; coughing up or vomiting fresh or dried blood that looks like coffee grounds; severe headache; and weakness. 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.
Drug and food interactions
Applies to: dicumarol
Nutrition and diet can affect your treatment with dicumarol. Therefore, it is important to keep your vitamin supplement and food intake steady throughout treatment. For example, increasing vitamin K levels in the body can promote clotting and reduce the effectiveness of dicumarol. While there is no need to avoid products that contain vitamin K, you should maintain a consistent level of consumption of these products. Foods rich in vitamin K include beef liver, broccoli, Brussels sprouts, cabbage, collard greens, endive, kale, lettuce, mustard greens, parsley, soy beans, spinach, Swiss chard, turnip greens, watercress, and other green leafy vegetables. Moderate to high levels of vitamin K are also found in other foods such as asparagus, avocados, dill pickles, green peas, green tea, canola oil, margarine, mayonnaise, olive oil, and soybean oil. However, even foods that do not contain much vitamin K may occasionally affect the action of dicumarol. There have been reports of patients who experienced bleeding complications and increased INR or bleeding times after consuming large quantities of cranberry juice, mangos, grapefruit, grapefruit juice, grapefruit seed extract, or pomegranate juice. Again, you do not need to avoid these foods completely, but it may be preferable to limit their consumption, or at least maintain the same level of use while you are receiving dicumarol. Talk to a healthcare provider if you are uncertain about what foods or medications you take that may interact with dicumarol. 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.
When dicumarol is given with enteral (tube) feedings, you may interrupt the feeding for one hour before and one hour after the dicumarol dose to minimize potential for interaction. Feeding formulas containing soy protein should be avoided.

Drug Interaction Classification
|Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit.|
|Moderately clinically significant. Usually avoid combinations; use it only under special circumstances.|
|Minimally clinically significant. Minimize risk; assess risk and consider an alternative drug, take steps to circumvent the interaction risk and/or institute a monitoring plan.|
|No interaction information available.|
