Question: does gabapentin cause urinary problems?
Answer: Discussion. To the best of our knowledge, the literature includes just 5 cases of gabapentin-induced incontinence, 3 of which involved both rectal and urinary incontinence and 2 involved only urinary incontinence. In all cases, incontinence occurred after 1–4 weeks of gabapentin treatment at dosages of 600–3600 mg/day.
