Interactions between your drugs

Moderate

revefenacin leniolisib

Applies to: revefenacin and leniolisib

Leniolisib may increase the blood levels of revefenacin following oral inhalation. This may increase side effects such as drowsiness, blurred vision, dry mouth, heat intolerance, flushing, decreased sweating, difficulty urinating, abdominal cramping, constipation, rapid heart beat, confusion, memory problems, and glaucoma. Although serious side effects are not very common with inhaled products such as revefenacin because only limited amounts of the medication generally get absorbed into the bloodstream from the lungs, they can sometimes occur, especially in the elderly or when combined with medications that can impair its clearance from the body. Talk to your doctor if you have any questions or concerns. Your doctor may be able to prescribe alternatives that do not interact. You should avoid activities requiring mental alertness such as driving or operating hazardous machinery until you know how these medications affect you. Also keep your eyes closed or use an eye mask during inhalation to avoid having the medication get into the eyes, which can cause blurry vision and eye pain as well as increase absorption of the medication into the bloodstream. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

Drug and food interactions

Moderate

leniolisib food

Applies to: leniolisib

Consumer information for this interaction is not currently available.

MONITOR: Coadministration with inhibitors of CYP450 3A4 including grapefruit or grapefruit juice may increase the plasma concentrations of leniolisib, which undergoes extensive CYP450 3A4-mediated first-pass metabolism in the gut wall and liver. In general, the effect of grapefruit juice is concentration-, dose- and preparation-dependent, and can vary widely among brands. Certain preparations of grapefruit juice (e.g., high dose, double strength) have sometimes demonstrated potent inhibition of CYP450 3A4, while other preparations (e.g., low dose, single strength) have typically demonstrated moderate inhibition. Pharmacokinetic interactions involving grapefruit juice are also subject to a high degree of interpatient variability, thus the extent to which a given patient may be affected is difficult to predict.

MANAGEMENT: Patients who regularly consume grapefruit or grapefruit juice should be monitored for adverse effects and altered plasma concentrations of leniolisib. Some authorities recommend to avoid grapefruit products during leniolisib treatment (UK).

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.
