MONITOR: Probiotic use during immunosuppressant or intense antineoplastic therapy may theoretically increase the risk of infections from the live microorganisms contained in probiotic products. Patients may be immunosuppressed if they have recently received or are receiving alkylating agents, antimetabolites, radiation, some antirheumatic agents, high dosages of corticosteroids or adrenocorticotropic agents, or long-term topical or inhaled corticosteroids. Although probiotics are generally considered safe, with minimal to low pathogenicity, infections such as bacteremia and endocarditis with various strains commonly found in probiotics (e.g., lactobacilli, bifidobacteria, Bacillus subtilis) have been rarely reported, primarily in critically ill patients or patients with significant underlying medical conditions such as malignancy, organ transplantation, AIDS, valvular heart disease, diabetes mellitus, recent surgery, or compromised immune system. Lactobacillus bacteremia has also been reported following endoscopy. In addition, cases of lactobacillus pneumonia and liver abscess, as well as Saccharomyces fungemia, pneumonia, liver abscess, peritonitis and vaginitis, have been described in the medical literature.

MANAGEMENT: Caution is advised when probiotics are used during immunosuppressant or intense antineoplastic therapy. It may be advisable to avoid using probiotics, particularly products containing saccharomyces boulardii, in patients who are significantly immunosuppressed unless benefits are anticipated to outweigh the potential risk of infection.

Drug and food interactions

Moderate

ifosfamide food

Applies to: ifosfamide

GENERALLY AVOID: Grapefruit and/or grapefruit juice may reduce the efficacy of ifosfamide, whose anticancer effect is dependent on its activation to the 4-hydroxyifosfamide metabolite via CYP450 3A4. The proposed mechanism is inhibition of CYP450 3A4 metabolism by certain compounds present in grapefruit. There are no data available about the effects of grapefruit on ifosfamide. However, in a small study, 8 patients with incurable malignancies received ifosfamide 3 g/m2 by infusion with the potent CYP450 3A4 inhibitor ketoconazole 200 mg orally twice daily for 4 days starting 1 day before the ifosfamide infusion. Ketoconazole decreased the clearance of ifosfamide by 11%, decreased systemic exposure (AUC) of the active metabolite 4-hydroxyifosfamide by 30%, and increased the AUC of the inactive but potentially neurotoxic metabolite 2-dechloroethylifosfamide by 23%, as compared to control. Because pharmacokinetic interactions involving grapefruit juice are often subject to a high degree of interpatient variability, the extent to which a given patient may be affected is difficult to predict.

GENERALLY AVOID: Alcohol may potentiate the neurotoxic effects of ifosfamide. Use in combination may result in additive central nervous system depression and/or impairment of judgment, thinking, and psychomotor skills. In addition, ifosfamide therapy may cause gastrointestinal disorders and alcohol consumption may increase nausea and vomiting.

MANAGEMENT: Given the potential for reduced efficacy of ifosfamide and increased risk of neurotoxicity and nephrotoxicity it may be advisable for patients to avoid consumption of grapefruit, grapefruit juice, or supplements that contain grapefruit during treatment with ifosfamide. In addition, patients receiving ifosfamide should be warned of the increased risk of neurotoxicity, nausea and vomiting when used in combination with alcohol. Patients should avoid or limit the consumption of alcohol during treatment with ifosfamide.

Drug Interaction Classification

These classifications are only a guideline. The relevance of a particular drug interaction to a specific individual is difficult to determine. Always consult your healthcare provider before starting or stopping any medication.
Major Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit.
Moderate Moderately clinically significant. Usually avoid combinations; use it only under special circumstances.
Minor 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.
Unknown No interaction information available.
