  • Clobazam + Cannabidiol— Concomitant use increases plasma concentrations of N-desmethylclobazam (active metabolite), which may increase risk of c…
  • Clobazam + Cns Depressants— Concomitant use increases risk of sedation and somnolence; effects may be potentiated.
  • Clobazam + Drugs Metabolized By Cyp2d6— Clobazam inhibits CYP2D6, potentially increasing exposure to these drugs and requiring dose adjustment.
  • Clobazam + Eslicarbazepine Acetate— Eslicarbazepine acetate can inhibit CYP2C19, causing increased plasma concentrations of clobazam. Dose adjustment may be…
  • Clobazam + Fenfluramine— Coadministration with stiripentol increases fenfluramine plasma concentrations. Dose adjustment required; maximum daily …
  • Clobazam + Fluconazole— Dosage adjustment of clobazam oral suspension may be necessary when co-administered with strong CYP2C19 inhibitors (e.g.…
