Interactions between your drugs

Major

rifAMPin isoniazid

Applies to: IsonaRif (isoniazid / rifampin) and IsonaRif (isoniazid / 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.

Moderate

isoniazid flibanserin

Applies to: IsonaRif (isoniazid / rifampin) and flibanserin

Isoniazid may increase the blood levels of flibanserin. In some cases, this may increase the risk of side effects such as drowsiness and decreases in blood pressure that can lead to dizziness, lightheadedness, fainting, and accidental injury. You should take flibanserin at bedtime to minimize the risk of these effects. 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 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.

Drug and food interactions

Major

flibanserin food

Applies to: flibanserin

Do not use alcohol too close to the dosing time of flibanserin. Doing so can cause excessive drowsiness and decreases in blood pressure, which may lead to dizziness, lightheadedness, fainting, and accidental injury. Take flibanserin at bedtime to minimize the risk of these effects. It is recommended that you stop drinking alcohol at least two hours before taking flibanserin; otherwise, you should just skip the flibanserin dose that evening. Alcohol should not be consumed until at least the morning after taking flibanserin at bedtime. Because grapefruit juice can significantly increase the blood levels of flibanserin, you should also avoid the consumption of grapefruit and grapefruit juice during treatment. 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.

Moderate

rifAMPin food

Applies to: IsonaRif (isoniazid / 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: IsonaRif (isoniazid / 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.
