Consumer:Consumer information for this minor interaction is not currently available. Some minor drug interactions may not be clinically relevant in all patients. Minor drug interactions do not usually cause harm or require a change in therapy. However, your healthcare provider can determine if adjustments to your medications are needed.
Professional:Coadministration with inhibitors of CYP450 2C19 may theoretically increase the plasma concentrations of phenobarbital, which is a substrate of the isoenzyme. Some studies have reported an approximately 20% decrease in the total clearance of phenobarbital in individuals who are poor metabolizers of CYP450 2C19, although an interaction with specific CYP450 2C19 inhibitors has not been reported. Other studies have found no significant difference in the pharmacokinetics of phenobarbital amongst subjects with various CYP450 2C19 genotypes, which would suggest a minor role of CYP450 2C19 in the overall clearance of phenobarbital. No precautions appear to be necessary during coadministration of phenobarbital with CYP450 2C19 inhibitors. However, dosage adjustments may be necessary if an interaction is suspected.
