Correct answer: EWithhold further routine doses and obtain urgent renal dose review

Gabapentin is renally eliminated and requires substantial dose reduction in severe renal impairment. Confusion, ataxia and myoclonus can reflect accumulation and require urgent clinical assessment and dose interruption; pregabalin also needs renal adjustment.
