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

Major

tazemetostat food

Applies to: Tazverik (tazemetostat)

GENERALLY AVOID: Consumption of grapefruit or grapefruit juice during tazemetostat therapy may significantly increase the plasma concentrations of tazemetostat. The proposed mechanism is inhibition of the CYP450 3A4-mediated metabolism of tazemetostat by certain compounds in grapefruit. Because grapefruit juice inhibits primarily intestinal rather than hepatic CYP450 3A4, the magnitude of interaction is greatest for those drugs that undergo significant presystemic metabolism by CYP450 3A4 (i.e., drugs with low oral bioavailability). According to the product labeling, coadministration of tazemetostat (400 mg twice daily) with the moderate CYP450 3A4 inhibitor fluconazole increased the tazemetostat steady state exposure (AUC 0 to 8 hours) by 3.1-fold and peak plasma concentration by 2.3-fold. In general, the effect of grapefruit juice is concentration-, dose- and preparation-dependent, and can vary widely among brands. Certain preparations of grapefruit juice (e.g., high dose, double strength) have sometimes demonstrated potent inhibition of CYP450 3A4, while other preparations (e.g., low dose, single strength) have typically demonstrated moderate inhibition. Pharmacokinetic interactions involving grapefruit juice are also subject to a high degree of interpatient variability, thus the extent to which a given patient may be affected is difficult to predict. Clinically, this interaction may result in an increased risk of the frequency or severity of adverse reactions due to tazemetostat such as hemorrhage, pleural effusion, skin infection, dyspnea, pain, and respiratory distress.

MANAGEMENT: The manufacturer advises that patients treated with tazemetostat should avoid consumption of grapefruit or grapefruit juice.

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.
