Interactions between your drugs

Major

erdafitinib cenobamate

Applies to: erdafitinib and cenobamate

ADJUST DOSE: Coadministration with moderate inducers of CYP450 2C9 or 3A4 may decrease the plasma concentrations and therapeutic effects of erdafitinib. The mechanism is induction of CYP450 2C9- or 3A4-mediated metabolism of erdafitinib, which has been shown to be metabolized by these isoenzymes.

MANAGEMENT: According to the manufacturer, if a moderate CYP450 2C9 or 3A4 inducer is coadministered at the start of erdafitinib therapy, the recommended dose of erdafitinib should be administered. If a moderate CYP450 2C9 or 3A4 inducer is coadministered after the initial dose increase period, the dose of erdafitinib may be increased up to 9 mg once daily based on serum phosphate levels and tolerability. When a moderate CYP450 2C9 or 3A4 inducer is discontinued, the current dose of erdafitinib may be continued in the absence of erdafitinib toxicity.

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.
