Does metronidazole and phenobarbital have any concerning interactions?

Phenobarbital speeds up liver activity, which can have an affect on drugs that are metabolized by the liver, such as metronidazole. That means that it may be metabolized more rapidly, requiring an adjustment in the dose of metronidazole. I would speak to your vet about this interaction.
