Recurrent Falls, Nighttime Sedation, and Bladder Symptoms
An 84-year-old woman presents after her third fall in six months, this time in the bathroom at night; she had no loss of consciousness and no head strike, but she has a 2-cm bruise over the left hip and can bear weight. She lives alone in a two-story home with a bedroom upstairs and one bathroom downstairs. Medications: lorazepam 1 mg at bedtime, oxybutynin 5 mg twice daily, zolpidem 5 mg as needed, sertraline 50 mg daily, metoprolol succinate 50 mg daily, lisinopril 20 mg daily, and calcium/vitamin D. Blood pressure is 118/70 seated and 96/60 after standing; pulse 62. She reports urinary urgency and nocturia twice nightly. Gait is slow and wide-based; she uses a cane indoors but not at night. She is reluctant to stop her bedtime lorazepam because 'it is the only thing that helps me sleep.'
1. Which medications most likely contribute to her falls, and how would you sequence changes without destabilizing her sleep, blood pressure, or bladder symptoms?
Read the worked answer
The highest-yield contributors are lorazepam, zolpidem, and oxybutynin; metoprolol and lisinopril may compound orthostasis, but her seated pressure is acceptable and she is not symptomatic except after standing. I would not change everything at once. First, stop the as-needed zolpidem and avoid substituting another sedative; start CBT-I and sleep hygiene. Next, stop oxybutynin and begin a behavioral bladder program (timed voiding, caffeine reduction, pelvic floor exercise). Then taper lorazepam slowly over weeks because abrupt withdrawal can cause rebound insomnia, anxiety, and seizures. Recheck orthostatics and home BP after each change; if symptomatic orthostasis persists, reduce lisinopril or metoprolol in consultation with her cardiologist. Document a single-change-at-a-time plan and follow-up interval.
2. What elements of the fall evaluation should be completed today, and which can be deferred?

Today I would obtain a focused fall history (prodrome, syncope, palpitations, head strike, footwear, nighttime route), orthostatic vitals, vision screen, foot exam, and a gait/balance test such as the Timed Up and Go; I would examine the hip and obtain an X-ray only if there is focal tenderness, inability to bear weight, or worsening pain. I would screen cognition and review all medications. I would defer bone density, vitamin D testing, home safety evaluation, and physical therapy referral only until the acute assessment is complete-not omit them. An ECG is reasonable today if the history suggests syncope or arrhythmia; otherwise it can be scheduled. The key is to identify reversible contributors and arrange a home safety and therapy plan before discharge.
3. How would you address her nocturia and nighttime bathroom use to reduce fall risk?
Read the worked answer
Nocturia is both a fall risk and a bladder symptom. I would move her last fluid intake earlier, avoid caffeine and alcohol in the evening, add a bedside commode and motion-activated night lighting, and ensure a clear path to the bathroom. If she has leg edema, leg elevation or compression before bedtime may reduce overnight urine production. I would treat constipation and review whether oxybutynin is helping; stopping it may improve cognition and dry mouth but could transiently worsen urgency, so pair the change with timed voiding and pelvic floor training. I would not use a nighttime sedative to manage sleep. A bladder diary and follow-up in 2–4 weeks would guide further therapy.
