From the Guidelines
Cognitive behavioral therapy for insomnia (CBT-I) is the most effective treatment for sleep disturbances in patients with comorbid depression or anxiety, as it addresses the underlying thought patterns and behaviors that perpetuate sleep problems without medication side effects. Treatment options for sleep disturbances in patients with comorbid depression or anxiety include both non-pharmacological and pharmacological approaches.
- Non-pharmacological approaches include CBT-I, which involves sleep hygiene education, stimulus control, sleep restriction, relaxation techniques, and cognitive restructuring 1.
- Pharmacological options include SSRIs like sertraline (50-200 mg daily) or escitalopram (10-20 mg daily), which can treat both mood disorders and sleep disturbances, though they may initially worsen insomnia 1.
- Sedating antidepressants such as trazodone (25-100 mg at bedtime) or mirtazapine (7.5-45 mg at bedtime) can be particularly effective for short-term use, but carry risks of dependence and tolerance 1.
- Benzodiazepines like lorazepam (0.5-2 mg) or non-benzodiazepine hypnotics like zolpidem (5-10 mg) may be prescribed for short-term use, but carry risks of dependence and tolerance 1.
- Melatonin (1-5 mg) or melatonin receptor agonists like ramelteon (8 mg) offer alternatives with fewer side effects 1. Treatment should be individualized based on symptom pattern, comorbidities, medication interactions, and patient preferences, with regular follow-up to assess efficacy and adjust treatment as needed 1.
From the Research
Treatment Options for Sleep Disturbances
The treatment options for managing sleep disturbances, particularly in patients with comorbid depression or anxiety, include various medications. Some of the commonly used medications are:
- Melatonin: a hormone that regulates sleep-wake cycles 2
- Trazodone: an antidepressant that can help improve sleep quality 3, 4, 5
- Doxepin: a sedating antidepressant that can help with sleep continuity 4
- Ramelteon: a melatonin receptor agonist that can help with sleep-onset latency and total sleep time 3, 6
Efficacy and Safety of Sleep Medications
The efficacy and safety of these medications vary:
- Trazodone has been shown to be effective in improving sleep quality, but it can have adverse effects such as morning grogginess and orthostatic hypotension 4, 5
- Doxepin has been shown to be effective in enhancing sleep continuity, but it can have adverse effects such as dry mouth 4
- Melatonin has been shown to be effective in improving sleep quality, but its efficacy can vary depending on the dose and formulation 2
- Ramelteon has been shown to be effective in improving sleep-onset latency and total sleep time, but it can have adverse effects such as somnolence 3, 6
Considerations for Older Adults
In older adults, the safety and efficacy of sleep medications are a concern:
- Benzodiazepines and non-benzodiazepine receptor agonists should be used with caution due to their potential for adverse effects such as dementia, serious injury, and fractures 6
- Sedating low-dose antidepressants should only be used for insomnia when the patient has comorbid depression 6
- Ramelteon and suvorexant may be valuable options for older adults due to their minimal adverse effect profiles 6
