Interactions between your drugs
fluconazole terbinafine
Applies to: fluconazole, terbinafine
MONITOR: Inhibitors of CYP450 2C9 and 3A4 may increase the systemic exposure to terbinafine. In a clinical study, coadministration of single doses of fluconazole 100 mg and terbinafine 750 mg increased the maximum plasma concentration and AUC of terbinafine by 52% and 69%, respectively. Although clinical data are lacking, amiodarone and ketoconazole may also significantly increase the systemic exposure to terbinafine.
MANAGEMENT: It is advisable to monitor patients for side effects during coadministration, such as diarrhea, abdominal pain, liver function test abnormalities, rashes, urticaria, and pruritus.
