Interactions between your drugs

Moderate

sirolimus momelotinib

Applies to: sirolimus and momelotinib

MONITOR: Coadministration of momelotinib may increase the plasma concentrations and effects of drugs that are substrates of the P-glycoprotein (P-gp) efflux transporter. The proposed mechanism is increased exposure of the P-gp substrate due to inhibition of intestinal P-gp efflux transporter. However, clinical data are not available.

MANAGEMENT: Caution is recommended with the concomitant use of momelotinib and P-gp substrates, particularly those with a narrow therapeutic index. Dosage adjustments as well as clinical and laboratory monitoring should be considered whenever momelotinib is added to or withdrawn from therapy with these drugs. Individual product labeling for the coadministered drug may also be consulted for specific guidance.

Drug and food/lifestyle interactions

Moderate

sirolimus food/lifestyle

Applies to: sirolimus

ADJUST DOSING INTERVAL: Consumption of food can decrease the rate and extent of gastrointestinal absorption of sirolimus. Also, the consumption of grapefruit juice may result in increased sirolimus trough concentrations.

MANAGEMENT: Experts recommend that this drug be taken either at least one hour prior to eating or consistently with or without food to avoid variations in sirolimus blood levels. The manufacturer recommends against using grapefruit juice for dilution of sirolimus doses. Patients should be monitored for clinical and laboratory evidence of altered immunosuppressant effects.

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.
