Trazodone, a prescription antidepressant, can add modest nighttime sleep in dementia but carries overnight fall risk. Doctors prescribe it off-label for sleep, which means for a use outside its official approval, with no approved sleep dose. Families often face broken nights, daytime drowsiness, and worry about wandering or falls. The sections below describe the measured gain, its limits, the fall data, and the doses researchers tested.

How Much Sleep Was Gained?
The Cochrane review describes one 30-patient trial in moderate-to-severe Alzheimer's disease. In that trial, nightly 50 mg for two weeks added about 42 minutes of total sleep measured by actigraphy, a wrist movement sensor, according to the Cochrane review.
Sleep efficiency, the share of time in bed spent asleep, rose by 8.5 percentage points. A clinic study in Arquivos de Neuro-Psiquiatria followed 178 older dementia patients with sleep disorders. Trazodone was the most used sleep aid, taken by 35 people, and caregivers rated it effective in 65.7% of those users.
How Certain Is the Benefit?
Cochrane reviewers rated the sleep benefit as low certainty. The finding rests on a single small trial lasting only two weeks.
It showed no clear effect on nighttime awakenings or daytime sleep. For general adult insomnia, the American Academy of Sleep Medicine guideline takes a cautious view. It weakly recommends clinicians not use trazodone for sleep onset or sleep maintenance because harms approximately equal benefits, stated in the sleep-medicine guideline.
What Is the Overnight Fall Risk?
The DailyMed trazodone label warns about orthostatic hypotension, a blood pressure drop on standing, and syncope, a brief faint. It also warns about impaired judgment, thinking, and motor skills. These effects matter most during nighttime bathroom trips.
In nursing homes, low-dose trazodone did not look safer than other sleep drugs. About 8,000 new users at a median of 50 mg per day had the same 90-day rate of fall-related emergency visits or hospital stays, 6%, as matched benzodiazepine users, with similar fractures, reported by the NEJM Journal Watch summary. A Canadian Geriatrics Journal study of 3,002 Alberta nursing-home residents age 66 and older found similar rates of injurious falls, major fractures, and death for new trazodone versus new zopiclone use.
What Dose Was Studied and How Can Families Lower Risk?
The DailyMed label lists trazodone as approved only for major depressive disorder in adults. The dementia sleep trial used 50 mg nightly for two weeks.
The large nursing-home comparison used a median of 50 mg per day. Ask the prescriber about dose, timing, blood pressure, other sedating drugs, and when to stop. Families can lower overnight risk with simple steps.
- Keep a clear, lit path to the bathroom and a nightlight on
- Help the person sit, pause, then stand slowly at night
- Keep walker, glasses, and call bell within reach
- Track bedtime, wake times, daytime sleepiness, and any slips or falls to review at the next visit
