- Wyamycin S (erythromycin)
Interactions between your drugs
erythromycin danicopan
Applies to: Wyamycin S (erythromycin) and danicopan
Consumer information for this interaction is not currently available.
MONITOR: Coadministration with danicopan may increase the plasma concentrations of drugs that are substrates of the efflux transporters breast cancer resistance protein (BCRP) and/or P-glycoprotein (P-gp). The proposed mechanism involves decreased clearance due to inhibition of BCRP and P-gp by danicopan. In clinical drug interaction studies, when subjects were coadministered the BCRP substrate rosuvastatin (single 20 mg dose) with danicopan at steady state (200 mg three times daily for 4 days), the peak plasma concentration (Cmax) and systemic exposure (AUC) of rosuvastatin increased by 3.3-fold and 2.2-fold, respectively. In addition, when the P-gp substrate fexofenadine (single 180 mg dose) was coadministered with danicopan (150 mg three times daily for 4 days), the peak plasma concentration (Cmax) and systemic exposure (AUC) of fexofenadine increased by 1.4-fold and 1.6-fold, respectively. Similarly, when subjects were coadministered the P-gp substrate tacrolimus (single 2 mg dose) with danicopan (200 mg three times daily for 5 days), the Cmax and AUC of tacrolimus increased by 1.1-fold and 1.5-fold, respectively.
MANAGEMENT: Caution and clinical monitoring are recommended if danicopan is coadministered with drugs that are substrates of the transporters BCRP and/or P-gp, particularly sensitive substrates, or those with a narrow therapeutic range. Dosage adjustments as well as closer clinical and laboratory monitoring for the development of adverse effects may be appropriate for some drugs whenever danicopan is added to or withdrawn from therapy. Individual product labeling should be consulted for further guidance.

Drug and food interactions
erythromycin food
Applies to: Wyamycin S (erythromycin)
Food decreases the levels of erythromycin in your body. Take erythromycin on an empty stomach at least 30 minutes before or 2 hours after a meal. This will make it easier for your body to absorb the medication. However, some erythromycin products may be taken without regard to meals. Ask your healthcare provider about your particular prescription if you are uncertain of how to take it. Grapefruits and grapefruit juice may increase erythromycin levels but how this may affect you is not known. Do not increase or decrease the amount of grapefruit products in your diet without first talking to your doctor.
