Acetylcysteine: Serum concentration of Brincidofovir may be increased when it is combined with Acetylcysteine Aminohippuric acid: Serum concentration of Brincidofovir may be increased when it is combined with Aminohippuric acid Amprenavir: Blood concentration The clearance of Brincidofovir may be increased when it is combined with Amprenavir. Apalutamide: The excretion of Brincidofovir may be increased when combined with Apalutamide. Asunaprevir: The serum concentration of Brincidofovir may be increased when it is combined with Asunaprevir Ataluren: Ataluren, Atazanavir, Atorvastatin, Axitinib, Beclomethasone dipropionate: The serum concentration of Brincidofovir may be increased when it is combined. Combination with Beclomethasone dipropionate: OATP 1B1 and 1B3 Inhibitors: If possible, consider alternative drugs that are not OATP1B1 or 1B3 inhibitors. If concomitant use is required, increase monitoring for brincidofovir-associated adverse reactions (elevated transaminases and bilirubin, diarrhea or other gastrointestinal adverse events) and delay OATP1B1 or 1B3 inhibitors at least. at least 3 hours after taking brincidofovir.
