Interactions between your drugs

Minor

felbamate atogepant

Applies to: felbamate and atogepant

Coadministration with inducers of CYP450 3A4 may decrease the plasma concentrations of atogepant, which is primarily metabolized by the isoenzyme. When atogepant was administered in healthy study subjects with steady-state rifampin, a potent CYP450 3A4 inducer, atogepant peak plasma concentration (Cmax) and systemic exposure (AUC) decreased by approximately 30% and 60%, respectively. No dedicated drug interaction studies were conducted to assess concomitant use with moderate or weak CYP450 3A4 inducers. While moderate inducers can likely decrease atogepant exposure, clinically significant interaction is not expected with concomitant administration of weak inducers. No dosage adjustment of atogepant is needed when used with weak CYP450 3A4 inducers.

Drug and food interactions

Moderate

felbamate food

Applies to: felbamate

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.

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.
