Other Drug Interactions with Sofosbuvir Medication and or Class Anticonvulsants carbamazepine, oxcarbazepine, phenobarbital, phenytoin Antimycobacterials rifampin, rifabutin, rifapentin Rationale for Avoiding with Sofosbuvir Co-administration with these medications is likely to reduce concentrations of sofosbuvir leading to reduced sofosbuvir efficacy. Co-administration not recommended. Co-administration with these medications is likely to reduce concentrations of sofosbuvir leading to reduced sofosbuvir efficacy due to intestinal P-glycoprotein (P-gp) induction from rifampin. Herbal products St. John s Wort Co-administration with these medications is likely to reduce concentrations of sofosbuvir leading to reduced sofosbuvir efficacy due to intestinal P-glycoprotein (P-gp) induction associated with St. John s Wort. www.nynjaetc.org

www.nynjaetc.org Other Drug Interactions with Simeprevir (1 of 2) Medication and or Class Anticonvulsants - carbamazepine, oxcarbazepine, phenobarbital, phenytoin Antibiotics clarithromycin, erythromycin, telithromycin Antifungals fluconazole, itraconazole, ketoconazole, posaconazole, voriconazole Antimycobacterials rifampin, rifabutin, rifapentine Rationale for Avoiding with Simeprevir Co-administration with these medications is likely to reduce concentrations of simeprevir and lead to reduced simeprevir efficacy. Co-administration not recommended. Co-administration with these medications is likely to increase concentrations of either simeprevir or the antibiotic due to CYP3A4 and P-glycoprotein (P-gp) inhibition. Co-administration not recommended. Co-administration with these medications is likely to increase concentrations of simeprevir due to CYP3A4 inhibition from the antifungals. Co-administration not recommended. Co-administration with these medications is likely to reduce concentrations of simeprevir and lead to reduced simeprevir efficacy. Co-administration not recommended.

www.nynjaetc.org Other Drug Interactions with Simeprevir (2 of 2) Medication and or Class Corticosteroids dexamethasone Rationale for Avoiding with Simeprevir Co-administration with dexamethasone is likely to decrease concentrations of simeprevir and lead to reduced simeprevir efficacy. Co-administration not recommended. Propulsive cisapride Co-administration with cisapride may result in increased concentrations of cisapride leading to potential cardiac arrhythmias. Herbal products Milk Thistle, St. John s Wort Co-administration with milk thistle is likely to increase concentrations of simeprevir. Co-administration not recommended. Co-administration with St. John s Wort is likely to reduce concentrations of simeprevir leading to reduced simeprevir efficacy, due to intestinal P-glycoprotein (P-gp) induction associated with St. John s Wort.
