Medication for Sleep Disturbances
Primary Recommendation
Cognitive Behavioral Therapy for Insomnia (CBT-I) should be the first-line treatment for sleep disturbances, with low-dose trazodone (50-100mg at bedtime) as the preferred pharmacological option when behavioral interventions alone are insufficient. 1, 2
Treatment Algorithm
Step 1: Initiate Behavioral Interventions First
CBT-I is the gold standard and must be started immediately for all patients with sleep disturbances, regardless of whether medications will eventually be needed. 3, 1, 2 This approach provides sustained benefits for up to 2 years without risk of dependence or withdrawal. 1
Core CBT-I components include:
- Sleep restriction therapy: Limit time in bed to match actual sleep duration based on sleep logs, which enhances sleep drive and consolidates sleep. 2
- Stimulus control: Go to bed only when sleepy; leave bed if unable to sleep within 20 minutes; use bed only for sleep and sex. 2
- Cognitive therapy: Address maladaptive beliefs about sleep. 2
- Relaxation techniques: Progressive muscle relaxation or biofeedback. 2
Step 2: Implement Comprehensive Sleep Hygiene
Essential sleep hygiene measures must be implemented concurrently: 3, 1, 2
- Consistent sleep-wake schedule: Same bedtime and wake time daily, even on weekends. 3, 1
- Exercise timing: Morning or afternoon physical activity only; avoid evening exercise. 3, 1
- Light exposure: Bright light exposure during daytime hours. 3
- Caffeine restriction: Last caffeine dose before 4:00 PM (or ideally before noon). 1, 2
- Avoid alcohol and nicotine: Particularly near bedtime. 3
- Sleep environment: Dark, quiet, comfortable bedroom. 3, 1
- Nap management: If needed, limit to 15-20 minutes around noon only. 1
Step 3: Screen for Underlying Sleep Disorders
Before assuming primary insomnia, evaluate for treatable causes: 3, 2
- Obstructive sleep apnea: Use STOP questionnaire if excessive sleepiness with observed apneas or snoring; confirm with polysomnography or home sleep study. 3
- Restless legs syndrome: Check ferritin levels; levels <45-50 ng/mL indicate treatable cause. 3
- Narcolepsy: Consider if excessive sleepiness with cataplexy, frequent short naps, vivid dreams, or sleep paralysis. 3
- Medical contributors: Pain, nocturia, medication side effects. 2
- Psychiatric comorbidities: Depression and anxiety commonly coexist with sleep disturbances. 4, 5
Step 4: Add Pharmacotherapy When Behavioral Interventions Are Insufficient
If severe daytime impairment persists beyond 1 week of behavioral interventions, add pharmacotherapy. 1
Preferred Pharmacological Agent: Trazodone
Trazodone 50-100mg at bedtime is the most appropriate first-line medication for sleep disturbances, particularly when comorbid depression or anxiety is present. 1, 6
- Start with trazodone 50mg at bedtime
- Titrate to 100mg if insufficient response after 3-5 days
- Lower doses may be more effective for sleep than higher doses 7
Advantages of trazodone: 1
- Lower abuse potential compared to hypnotics
- Dual benefit for comorbid anxiety or depression
- No benzodiazepine-related risks
Important drug interactions to monitor: 6
- Avoid with strong CYP3A4 inhibitors (itraconazole, ketoconazole, clarithromycin) due to increased trazodone exposure and cardiac arrhythmia risk
- Monitor closely with CYP3A4 inducers (rifampin, carbamazepine, phenytoin) as they decrease trazodone exposure
- Avoid with other QT-prolonging drugs (quinidine, amiodarone, sotalol, ziprasidone)
- Increased bleeding risk with antiplatelet agents and anticoagulants; monitor INR closely with warfarin
Alternative FDA-Approved Hypnotics
If trazodone is contraindicated or ineffective, consider: 2
- Eszopiclone
- Temazepam
- Low-dose doxepin
These should only be used short-term (4 weeks maximum without reassessment) due to tolerance and dependence risks. 1, 2
Step 5: Medications to Absolutely Avoid
Benzodiazepines (including lorazepam) should be avoided due to: 1, 2, 8
- High risk of dependence and abuse (particularly problematic in patients with substance use history)
- Falls, confusion, and cognitive impairment
- Withdrawal seizure risk upon discontinuation
- Long-acting formulations cause accumulation and prolonged sedation
Antihistamines (diphenhydramine, doxylamine) should be avoided due to: 1, 2
- Anticholinergic effects
- Daytime sedation
- Delirium risk, especially in older adults
Antipsychotics should not be used as first-line treatment due to metabolic side effects. 2
Special Populations and Contexts
Older Adults
For elderly or debilitated patients, start with lower doses and increase gradually. 3, 8 The American Geriatrics Society emphasizes avoiding benzodiazepines entirely in this population due to heightened risks of falls, confusion, and cognitive impairment. 3, 1
REM Sleep Behavior Disorder
If violent dream enactment behaviors are present, consider REM sleep behavior disorder (RBD). 3 Diagnosis requires polysomnography showing increased electromyographic activity during REM sleep. 3
For confirmed RBD, clonazepam 0.5-1mg at bedtime is the most effective treatment (90% effective), though this represents an exception to the general avoidance of benzodiazepines. 3 Environmental safety measures are critical: remove dangerous objects, pad surfaces around bed, use heavy draperies on windows, consider placing mattress on floor. 3
Important caveat: Tricyclic antidepressants, MAOIs, and SSRIs can induce or exacerbate RBD and should be avoided in these patients. 3
Cancer Survivors
Physical activity interventions show particular promise in cancer survivors. 3 A randomized trial of 410 survivors found that standardized yoga improved global sleep quality, daytime functioning, and sleep efficiency while reducing sleep medication use. 3
Cannabis Withdrawal
Sleep disturbance occurs within 3 days of cannabis cessation and typically lasts up to 14 days. 1 The same treatment algorithm applies: CBT-I first, then trazodone 50-100mg if needed. 1 Patient education that withdrawal symptoms are time-limited is essential. 1
Monitoring and Follow-Up
Weekly reassessment during the first month is mandatory using validated tools like the Insomnia Severity Index. 1, 2
Plan medication taper after 4-8 weeks if sleep normalizes: 1, 2
- Use gradual taper to reduce withdrawal risk
- If withdrawal reactions develop, pause taper or increase to previous dose
- Continue CBT-I even after medication discontinuation to maintain gains
Monitor for medication side effects: 1, 2
- Residual daytime sedation
- Complex sleep behaviors
- Cardiac effects (with trazodone)
Critical Pitfalls to Avoid
Never start with pharmacotherapy alone without concurrent behavioral interventions – this creates medication dependence without addressing perpetuating factors like conditioned arousal and maladaptive sleep behaviors. 1, 2
Never prescribe hypnotics for longer than 4 weeks without reassessment – long-term use leads to tolerance and dependence. 1, 2
Never assume primary insomnia without screening for underlying sleep disorders – obstructive sleep apnea, restless legs syndrome, and other conditions require specific treatments. 3, 2
Never use benzodiazepines as first-line treatment – the risks far outweigh benefits except in the specific case of confirmed REM sleep behavior disorder. 3, 1, 2
