Interactions between your drugs

Moderate

pegfilgrastim trifluridine

Applies to: Neulasta (pegfilgrastim) and tipiracil / trifluridine

ADJUST DOSING INTERVAL: The safety and efficacy of recombinant human granulocyte colony-stimulating factors (rhG-CSF) administered simultaneously with cytotoxic agents, including cancer chemotherapy, have not been established. Theoretical concerns exist regarding their concomitant administration because hematopoietic growth factors stimulate myeloid cell proliferation while antineoplastic agents primarily target rapidly dividing cells.

MANAGEMENT: The prescribing information for pegfilgrastim, eflapegrastim, and efbemalenograstim alfa recommends that these products not be administered between 14 days before and 24 hours after antineoplastic agents.

Drug and food interactions

Moderate

trifluridine food

Applies to: tipiracil / trifluridine

ADJUST DOSING INTERVAL: Administration of trifluridine-tipiracil with a standardized high-fat, high-calorie meal has been shown to decrease trifluridine peak plasma concentration (Cmax) as well as tipiracil Cmax and systemic exposure (AUC) by approximately 40% compared to administration in a fasting state in patients with cancer given a single 35 mg/m2 dose. No change in trifluridine AUC was observed.

MANAGEMENT: Based on the observed correlation between increases in the Cmax of trifluridine and decreases in neutrophil counts, trifluridine-tipiracil should be taken within one hour after completion of the morning and evening meals.

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.
