Interactions between your drugs

Major

bromfenac ibritumomab tiuxetan

Applies to: bromfenac and ibritumomab

MONITOR CLOSELY: Coadministration of radiolabeled ibritumomab tiuxetan and drugs that interfere with platelet function or coagulation may potentiate the risk of bleeding complications. Radiolabeled ibritumomab tiuxetan commonly causes severe and prolonged thrombocytopenia, and the risk is increased further in patients with mild thrombocytopenia at the initiation of therapy. Haemorrhage, including fatal cerebral hemorrhage, has occurred in a minority of patients in clinical studies. The median time to thrombocyte nadir was 7 to 9 weeks, and the median duration of thrombocytopenia was 22 to 35 days. However, in less than 5% of the cases, patients experienced severe cytopenia that extended beyond 12 weeks following administration of the radiolabeled ibritumomab tiuxetan therapeutic regimen. Platelet transfusions were given to 22% of patients in clinical trials.

MANAGEMENT: Caution is advised if radiolabeled ibritumomab tiuxetan is used in combination with drugs that interfere with platelet function or coagulation. Close clinical and laboratory observation for bleeding complications is recommended during and after treatment.

Drug and food interactions

Moderate

bromfenac food

Applies to: bromfenac

ADJUST DOSE: In-vivo studies have demonstrated that the absorption of bromfenac is greatly reduced if the drug is taken within three and one-half hours following a high fat meal. The concomitant administration of a high fat meal has led to a 75% reduction in peak plasma concentrations and a 60% reduction in total area under the curve. The mechanism has not been described.

MANAGEMENT: An increased dosage of bromfenac (from 25 to 50 mg) may be needed if a high fat meal is consumed. The clinician may want to warn the patient about subtherapeutic analgesic effects if high fat meals are regularly consumed.

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.
