From the Guidelines
For an 85-year-old with dementia experiencing sleep difficulties despite being on Xanax, hydrocodone, and trazodone, I strongly recommend discontinuing the use of these medications and prioritizing non-pharmacological interventions to improve sleep quality. The patient's current medication regimen may be contributing to sleep disturbances, particularly as Xanax and hydrocodone can sometimes cause paradoxical reactions in elderly patients with dementia 1.
Non-Pharmacological Interventions
Non-pharmacological interventions should be prioritized, including:
- Establishing a consistent sleep schedule
- Creating a calm bedtime routine
- Ensuring the bedroom is comfortable and quiet
- Limiting daytime napping
- Increasing daytime light exposure
- Reducing evening fluid intake
Medication Adjustments
If medication adjustments are necessary, the physician might consider exploring alternatives like low-dose melatonin (1-2mg) or mirtazapine (7.5-15mg), although the evidence for these alternatives is not strong 1. However, given the patient's advanced age and dementia, minimizing sedating medications is crucial to prevent falls, confusion, and worsening cognitive function.
Risks of Current Medications
The use of benzodiazepines, such as Xanax, and trazodone has been advised against in the treatment of chronic insomnia disorder due to their potential harms and adverse effects, including risk for dependency and diversion, falls and cognitive impairment in older patients, hypoventilation in patients with respiratory conditions, and neuromuscular diseases 1. Antihistamines and antipsychotics are also not recommended for the treatment of chronic insomnia disorder due to their sedating effects and potential for adverse events 1.
Prioritizing Patient Safety
Given the potential risks associated with the patient's current medication regimen, discontinuing the use of Xanax, hydrocodone, and trazodone and prioritizing non-pharmacological interventions is the most appropriate course of action to improve the patient's sleep quality and overall well-being.

The patient is already taking Xanax (alprazolam), which is a benzodiazepine, and is still experiencing insomnia. The drug label reports insomnia as a common adverse event associated with the use of alprazolam.
- The patient's dementia and use of hydrocodone and trazodone may also be contributing factors to their insomnia.
- Considering the patient's complex medical condition and medication regimen, it is likely that simply increasing the dose of Xanax or adding another benzodiazepine would not be effective and may even worsen their condition.
- A more comprehensive approach to managing the patient's insomnia, such as addressing underlying sleep disorders, optimizing their medication regimen, and implementing non-pharmacological interventions, may be necessary 2.
From the Research
Sleep Disturbances in Dementia Patients
- Sleep disturbances are common in dementia patients, and drug treatment is often sought to alleviate these problems 3.
- However, there is significant uncertainty about the efficacy and adverse effects of various hypnotic drugs in this vulnerable population 3.
Trazodone Use in Dementia Patients
- Trazodone 50 mg administered at night for two weeks significantly improved total nocturnal sleep time and sleep efficiency in patients with Alzheimer's disease 3.
- However, trazodone use has also been associated with an increased risk of cognitive impairment in very old women 4.
- A retrospective study found that long-term use of trazodone was associated with delayed cognitive decline in patients with Alzheimer's dementia, mild cognitive impairment, or normal cognition 5.
Risks Associated with Trazodone Use
- Trazodone use is associated with similar rates of falls or major osteoporotic fractures compared to atypical antipsychotics in older adults with dementia 6.
- Trazodone use is also associated with a lower rate of mortality compared to atypical antipsychotics in older adults with dementia 6.
Management of Sleep Disturbances in Dementia Patients
- There is a lack of evidence to guide drug treatment of sleep problems in dementia patients, particularly for commonly prescribed medications such as benzodiazepines and non-benzodiazepine hypnotics 3.
- Non-pharmacological interventions, such as morning bright light therapy, may be beneficial in improving sleep outcomes in dementia patients 3.
- A comprehensive approach to managing sleep disturbances in dementia patients should consider the complex needs of these patients, including their medical, psychological, and social needs 7.
