Rabeprazole decreases the concentration of ketoconazole in the plasma (in 33%), increases the concentration of digoxin (in 22%), and does not interact with liquid antacids. Rabeprazole is compatible with any medicine metabolized by the CYP450 (theophylline, warfarin, diazepam, phenytoin).
Studies in mice and rats indicated the symptoms of acute toxicity due to overdose included: hypoactivity, labored respiration, convulsion, diarrhea, tremor, and coma. A study in dogs indicated that a dose of 2000 mg/kg was not lethal.
