Interactions between your drugs

Moderate

caffeine bendamustine

Applies to: caffeine and bendamustine

MONITOR: Coadministration with inhibitors of CYP450 1A2 may increase the plasma concentrations of bendamustine, which has been shown in vitro to be metabolized by the isoenzyme.

MANAGEMENT: Caution is advised if bendamustine is used in combination with CYP450 1A2 inhibitors. Close monitoring for toxicity (e.g., neutropenia, thrombocytopenia, anemia, leukopenia, infections, bleeding complications) is recommended, and the bendamustine dosage adjusted as necessary.

Applies to: caffeine

The effect of grapefruit juice on the pharmacologic activity of caffeine is controversial. One report suggests that grapefruit juice increases the effect of caffeine. The proposed mechanism is inhibition of cytochrome P-450 metabolism of caffeine. However, a well-conducted pharmacokinetic/pharmacodynamic study did not demonstrate this effect. The clinical significance of this potential interaction is unknown.

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.
