Interactions between your drugs

Minor

nefazodone darolutamide

Applies to: nefazodone and darolutamide

Coadministration with inhibitors of CYP450 3A4 and/or P-glycoprotein (P-gp) may increase the plasma concentrations of darolutamide, which is a substrate of both the isoenzyme and the efflux transporter. When darolutamide was coadministered with itraconazole, a dual P-gp and potent CYP450 3A4 inhibitor, mean darolutamide peak plasma concentration (Cmax) and systemic exposure (AUC) increased by 40% and 70%, respectively, compared to administration of darolutamide alone. The interaction has not been studied with less potent inhibitors or lone inhibitors of CYP450 3A4 or P-gp. Caution is advised when darolutamide is used with CYP450 3A4 or P-gp inhibitors. Patients should be monitored more frequently for adverse effects such as fatigue, hypertension, neutropenia and abnormal liver function tests, and the darolutamide dosage adjusted as necessary in accordance with the product labeling.

Drug and food interactions

Moderate

nefazodone food

Applies to: nefazodone

GENERALLY AVOID: Alcohol may potentiate some of the pharmacologic effects of CNS-active agents. Use in combination may result in additive central nervous system depression and/or impairment of judgment, thinking, and psychomotor skills.

MANAGEMENT: Patients receiving CNS-active agents should be warned of this interaction and advised to avoid or limit consumption of alcohol. Ambulatory patients should be counseled to avoid hazardous activities requiring complete mental alertness and motor coordination until they know how these agents affect them, and to notify their physician if they experience excessive or prolonged CNS effects that interfere with their normal activities.

Moderate

darolutamide food

Applies to: darolutamide

ADJUST DOSING INTERVAL: Food enhances the oral absorption of darolutamide. According to the prescribing information, bioavailability of darolutamide increased by 2.0 to 2.5-fold when administered with food. A similar increase in exposure was observed for the active metabolite keto-darolutamide.

MANAGEMENT: Darolutamide should be administered with food.

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.
