Interactions between your drugs
rifAMPin isoniazid
Applies to: isoniazid / pyrazinamide / rifampin and isoniazid / pyrazinamide / rifampin
Using isoniazid together with rifAMPin can cause serious side effects that may affect your liver. You should avoid or limit the use of alcohol while being treated with these medications. Your doctor may already be aware of the risks but has determined that this is the best course of treatment for you, has taken appropriate precautions, and is monitoring you closely for any potential complications. If you develop severe liver problems, you may need a dose adjustment or an interruption in therapy. Call your doctor immediately if you have fever, chills, joint pain or swelling, unusual bleeding or bruising, skin rash, itching, loss of appetite, fatigue, nausea, vomiting, abdominal pain, dark colored urine, light colored stools, and/or yellowing of the skin or eyes, as these may be signs and symptoms of liver damage. Talk to your healthcare provider if you have any questions or concerns. 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.
rifAMPin pyrazinamide
Applies to: isoniazid / pyrazinamide / rifampin and isoniazid / pyrazinamide / rifampin
Ask your doctor before using rifAMPin together with pyrazinamide. This can cause damage to the liver. Liver function and drug levels in the blood may be monitored with blood tests during treatment. Call your doctor if you experience fever, rash, loss of appetite, nausea, vomiting, fatigue, right upper abdominal pain, dark urine, and jaundice. You may need a dose adjustment or special tests to safely take 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.
rifAMPin dicumarol
Applies to: isoniazid / pyrazinamide / rifampin and dicumarol
Ask your doctor before using dicumarol together with rifAMPin. This combination may reduce the effects of dicumarol. 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. You may need a dose adjustment in addition to testing of your prothrombin time or International Normalized Ratio (INR). 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.
isoniazid pyrazinamide
Applies to: isoniazid / pyrazinamide / rifampin and isoniazid / pyrazinamide / rifampin
Isoniazid may cause liver problems and using it with other medications that can also affect the liver, such as pyrazinamide, may increase that risk. You should avoid or limit the use of alcohol while being treated with these medications. Your doctor may already be aware of the risks but has determined that this is the best course of treatment for you, has taken appropriate precautions, and is monitoring you closely for any potential complications. If you develop severe liver problems, you may need a dose adjustment or an interruption in therapy. Call your doctor immediately if you have fever, chills, joint pain or swelling, unusual bleeding or bruising, skin rash, itching, loss of appetite, fatigue, nausea, vomiting, abdominal pain, dark colored urine, light colored stools, and/or yellowing of the skin or eyes, as these may be signs and symptoms of liver damage. Talk to your healthcare provider if you have any questions or concerns. 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.
isoniazid dicumarol
Applies to: isoniazid / pyrazinamide / rifampin and dicumarol
Using isoniazid together with dicumarol can cause you to bleed more easily. You may need a dose adjustment in addition to testing of your prothrombin time or International Normalized Ratio (INR). Call your doctor promptly if you have any 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
rifAMPin food
Applies to: isoniazid / pyrazinamide / rifampin
Food can decrease the levels of rifAMPin in your body. Taking rifAMPin on an empty stomach (at least 30 minutes before or 2 hours after a meal) will make it easier for your body to absorb the medication. Avoid drinking alcohol while taking rifAMPin because alcohol use may increase the risk of damage to your liver. It is important to seek immediate medical care if you experience any severe side effects or symptoms of liver damage such as fever, chills, joint pain or swelling, unusual bleeding or bruising, skin rash, itching, loss of appetite, fatigue, nausea, vomiting, dark colored urine, and/or yellowing of the skin or eyes. 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.
isoniazid food
Applies to: isoniazid / pyrazinamide / rifampin
Food can decrease the levels of isoniazid in your body. Taking isoniazid on an empty stomach (at least 30 minutes before or 2 hours after a meal) will make it easier for your body to absorb the medication. Avoid drinking alcohol while taking isoniazid because alcohol use may increase the risk of damage to your liver and your risk of experiencing a condition known as peripheral neuropathy (i.E., weakness, numbness, and pain typically in the hands and feet). Your doctor may advise you to take a vitamin B6 (pyridoxine) supplement during your treatment to help prevent peripheral neuropathy. Isoniazid may interact with foods containing histamine or tyramine (e.G., aged cheese, cured meats such as sausages and salami, fava beans, sauerkraut, soy sauce, beer, red wine, skipjack, tuna, mackerel, salmon), which can cause symptoms like headache, sweating, flushing, palpitations, dizziness, lightheadedness, or feeling faint. These foods should generally be avoided. It is important to seek immediate medical care if you experience any severe side effects or symptoms of liver damage such as fever, chills, joint pain or swelling, unusual bleeding or bruising, skin rash, itching, loss of appetite, fatigue, nausea, vomiting, dark colored urine, and/or yellowing of the skin or eyes. 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.
dicumarol food
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.
