Drug interactions
Moderate drug interactions
Moderate:
ifosfamide taurursodiol
Applies to: ifosfamide and sodium phenylbutyrate / taurursodiol
Taurursodiol may alter the blood levels and effects of ifosfamide. 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. Contact your doctor if your condition changes or you experience increased side effects. 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.
Food/lifestyle interactions
Moderate food/lifestyle interactions
Moderate:
ifosfamide Food/Lifestyle
Applies to: ifosfamide
Do not consume grapefruit or grapefruit juice while you are receiving treatment with ifosfamide, as this may decrease the anticancer effects of ifosfamide and may increase its adverse effects on your nervous system and your kidneys. Do not use alcohol while you are receiving treatment with ifosfamide. This may increase nervous system side effects such as somnolence, dizziness, confusion, difficulty concentrating, and impairment of thinking and judgment; and may also increase nausea and vomiting. Talk to your doctor or pharmacist if you have questions on how to take this or other medications you are prescribed. Also, avoid activities requiring mental alertness such as driving or operating hazardous machinery until you know how the medication affects you. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medication without first talking to your doctor.
Moderate:
sodium phenylbutyrate Food/Lifestyle
Applies to: sodium phenylbutyrate / taurursodiol
Food may affect the absorption of sodium phenylbutyrate. A high-fat, high-calorie meal (approximately 800 to 1000 calories; 500 to 600 calories from fat, 250 calories from carbohydrate, 150 calories from protein) has been shown to reduce the absorption of sodium phenylbutyrate, although it is unknown what impact this may have on the overall effectiveness of the medication. The manufacturer recommends taking sodium phenylbutyrate before a meal or snack. This is especially important if you weigh less than 70 kg (approximately 154 pounds). Talk to your doctor or pharmacist if you have questions on how to take this or other medications you are prescribed. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medication without first talking to your doctor.
Disease interactions
19 potential interactions Applies to: 15 conditions, including Heart Failure, Peripheral Neuropathy, Fever, Psychosis, and Gallbladder Disease.
Biliary Obstruction
Moderate:
sodium phenylbutyrate / taurursodiol
The taurursodiol in sodium phenylbutyrate / taurursodiol has a moderate potential interaction with Biliary Obstruction.
Sodium phenylbutyrate-taurursodiol contains taurursodiol, a bile acid. In patients with disorders that interfere with bile acid circulation, there may be an increased risk for diarrhea and patients should be monitored appropriately. Other conditions such as pancreatic insufficiency, intestinal malabsorption, or intestinal diseases that may alter the concentration of bile acids, may also lead to decreased absorption of this drug and its components. Consider consulting with a GI specialists with experience managing these GI disorders. Patients with disorders of enterohepatic circulation (e.g., biliary infection, active cholecystitis, etc.), severe pancreatic disorders (e.g., pancreatitis), and intestinal disorders that may alter concentrations of bile acids (e.g., ileal resection, regional ileitis, etc.) were excluded from clinical studies and there is no experience in patients with these conditions. Caution is advised.
Bleeding Disorder
Major:
ifosfamide
Ifosfamide has a major potential interaction with Bleeding Disorder.
Treatment with ifosfamide may cause myelosuppression and significant suppression of immune responses, which can lead to severe or fatal infections. Patients should be instructed to immediately report any signs or symptoms suggesting bone marrow suppression such as fever, sore throat, local infection, or bleeding. Complete blood counts should be obtained prior to administration of each dose and unless clinically essential, ifosfamide should be withheld if white blood cell counts falls below 1,500 to 2,000/mm3 and/or platelet counts falls below 50,000/mm3. Ifosfamide should be given cautiously, if at all, to patients with presence of an infection, severe immunosuppression or compromised bone marrow reserve, as indicated by leukopenia, granulocytopenia, extensive bone marrow metastases, prior radiation therapy, or prior therapy with other cytotoxic agents.
Bone Marrow Depression/Low Blood Counts
Major:
ifosfamide
Ifosfamide has a major potential interaction with Bone Marrow Depression/Low Blood Counts.
Treatment with ifosfamide may cause myelosuppression and significant suppression of immune responses, which can lead to severe or fatal infections. Patients should be instructed to immediately report any signs or symptoms suggesting bone marrow suppression such as fever, sore throat, local infection, or bleeding. Complete blood counts should be obtained prior to administration of each dose and unless clinically essential, ifosfamide should be withheld if white blood cell counts falls below 1,500 to 2,000/mm3 and/or platelet counts falls below 50,000/mm3. Ifosfamide should be given cautiously, if at all, to patients with presence of an infection, severe immunosuppression or compromised bone marrow reserve, as indicated by leukopenia, granulocytopenia, extensive bone marrow metastases, prior radiation therapy, or prior therapy with other cytotoxic agents.

Moderate:
sodium phenylbutyrate / taurursodiol
The sodium phenylbutyrate in sodium phenylbutyrate / taurursodiol has a moderate potential interaction with Central Nervous System Disorders.

Psychosis
Moderate:
ifosfamide

Renal Dysfunction
Major:

Moderate:
ifosfamide
Ifosfamide has a moderate potential interaction with Renal Dysfunction.
Ifosfamide is primarily eliminated by the kidney. Approximately 12% to 18% of ifosfamide is excreted unchanged in the urine. Additionally, iIfosfamide is both nephrotoxic and urotoxic. Hemorrhagic cystitis due to metabolites excreted in the urine can develop during therapy with ifosfamide. Adequate hydration and use of a prophylactic agent such as mesna prior to each course of ifosfamide therapy can reduce bladder irritation and hematuria. Clinical signs of renal toxicity such as elevation in BUN or serum creatinine or decrease in creatinine clearance have been reported. Therapy with ifosfamide should be administered cautiously in patients with a history of or predisposition to cystitis or impaired renal function. Close clinical monitoring of serum and urinary chemistries is recommended.
