Background: Undiagnosed phenytoin toxicity in elderly may pose dangers of falls and debility which could be otherwise totally averted. Clinicians need to be aware that though easily available, phenytoin is one of the difficult drugs to dose appropriately owing to its saturable metabolism and a narrow therapeutic window. The difficulty is compounded in the elderly, due to compromised  metabolism  and erratic clearance of the drug. Case Report: We present a case of an elderly man with fluctuating encephalopathy with a striking diurnal variation, ranging from stupor to a conscious and alert state during the course of the day, which turned out to be due to phenytoin toxicity. Conclusion: Phenytoin should be used with caution in the elderly.
