Interactions between your drugs

Major

chloramphenicol trifluridine

Applies to: chloramphenicol and Lonsurf (tipiracil / trifluridine)

GENERALLY AVOID: Coadministration of chloramphenicol with other agents that can cause bone marrow depression, aplastic anemia, or agranulocytosis may increase the risk and/or severity of hematologic toxicity. Serious and fatal blood dyscrasias (aplastic anemia, hypoplastic anemia, thrombocytopenia, granulocytopenia, and bone marrow depression) have been reported after short-term and long-term systemic therapy with chloramphenicol.

MANAGEMENT: Concurrent use of chloramphenicol with other agents that can cause bone marrow depression, aplastic anemia, or agranulocytosis, such as sulfonamides, nucleoside reverse transcriptase inhibitors, procainamide, phenylbutazone, clozapine, and depot formulations of antipsychotic drugs, should be avoided.

Drug and food interactions

Moderate

trifluridine food

Applies to: Lonsurf (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.
