Interactions between your drugs

Major

tiZANidine viloxazine

Applies to: tizanidine and viloxazine

CONTRAINDICATED: Coadministration of viloxazine, a potent inhibitor of CYP450 1A2, may significantly increase the risk of adverse reactions to sensitive CYP450 1A2 substrates or CYP450 1A2 substrates with a narrow therapeutic range. According to the prescribing information, viloxazine increased the systemic exposure (AUC) of caffeine, a probe CYP450 1A2 substrate, by nearly 6-fold without affecting its peak plasma concentration (Cmax).

MANAGEMENT: Concomitant use of viloxazine with sensitive CYP450 1A2 substrates or CYP450 1A2 substrates with a narrow therapeutic range such as alosetron, duloxetine, ramelteon, tasimelteon, tizanidine, or theophylline is contraindicated.
