Drug interactions between indinavir and warfarin
Interactions between your drugs
warfarin ↔ indinavir
Applies to:warfarin and indinavir
Using warfarin together with indinavir can alter the effects of warfarin. Call your doctor promptly if you have any signs of blood clots such as chest pain, shortness of breath, sudden loss of vision, or pain, redness or swelling in an extremity. This may also cause unusual bleeding or bruising, vomiting, blood in your urine or stools, headache, dizziness, or 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: warfarin
Nutrition and diet can affect your treatment with warfarin. 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 warfarin. 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 warfarin. There are reports of patients who experienced bleeding complications and increased INR or bleeding times after consuming large quantities of cranberry juice, mangos, 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 warfarin. Talk to a healthcare provider if you are uncertain about what foods or medications you take 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. When warfarin is given with enteral (tube) feedings, you may interrupt the feeding for one hour before and one hour after the warfarin dose to minimize potential for interaction. Feeding formulas containing soy protein should be avoided.
Applies to: indinavir
Large amounts of food decreases the levels of indinavir in your body. Indinavir should be taken on an empty stomach, at least 1 hour before or 2 hours after a meal. This will make it easier for your body to absorb the medication. Take indinavir with a full glass (8 ounces) of water or skim milk. You may also drink juice, coffee, or tea with this medication. Drink at least 6 glasses of water each day to prevent kidney stones while you are taking indinavir. If you prefer to take the medication with food, eat only a light meal, such as dry toast with jelly, or corn flakes with skim milk and sugar. Avoid eating a high-fat meal.
