Interactions between your drugs

Minor

lesinurad atogepant

Applies to: Duzallo (allopurinol / lesinurad) 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

allopurinol food

Applies to: Duzallo (allopurinol / lesinurad)

ADJUST DOSING INTERVAL: The tolerability of allopurinol may be improved by giving it after a meal. Additionally, when the dose is greater than 300 mg, dividing the total daily dose into smaller doses administered more often may be appropriate to help minimize gastrointestinal irritation.

MONITOR: Concomitant use of allopurinol with central nervous system (CNS) depressants, including alcohol, may potentiate adverse effects such as somnolence and sedation.

MANAGEMENT: To improve tolerability, some manufacturers suggest administering allopurinol after a meal. Additionally, if the daily dose is greater than 300 mg, administering allopurinol in divided doses may help reduce gastrointestinal intolerance. Patients should also be counseled to avoid or limit consumption of alcohol and to avoid activities requiring mental alertness such as driving or operating hazardous machinery until they know how the medication affects them.

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.
