All other adverse events in this population were reported in approximately 3% or fewer of those receiving Antizol (fomepizole) and were as follows:

Oral doses of Antizol (fomepizole) (10-20 mg/kg), via alcohol dehydrogenase inhibition, significantly reduced the rate of elimination of ethanol (by approximately 40%) given to healthy volunteers in moderate doses. Similarly, ethanol decreased the rate of elimination of Antizol (fomepizole) (by approximately 50%) by the same mechanism.
Reciprocal interactions may occur with concomitant use of Antizol (fomepizole) and drugs that increase or inhibit the cytochrome P450 system (e.g., phenytoin, carbamazepine, cimetidine, ketoconazole), though this has not been studied.
