Treatment of Insomnia in a 32-Year-Old with Anxiety
Cognitive Behavioral Therapy for Insomnia (CBT-I) should be initiated immediately as first-line treatment, and if pharmacotherapy is necessary due to severe impairment, add a short/intermediate-acting benzodiazepine receptor agonist like zolpidem 10 mg or eszopiclone 2-3 mg for short-term use only. 1, 2
First-Line Treatment: CBT-I
All adults with insomnia must receive CBT-I as initial treatment before or alongside any medication. 1 This is a strong recommendation based on moderate-quality evidence showing superior long-term outcomes compared to pharmacotherapy alone, with sustained benefits after discontinuation and minimal adverse effects. 1
CBT-I Components to Implement
- Stimulus control therapy: Use the bedroom only for sleep and sex; leave the bed if unable to fall asleep within 15-20 minutes; maintain consistent sleep and wake times. 1, 2
- Sleep restriction therapy: Limit time in bed to match actual sleep time (maintain sleep log for 1-2 weeks to determine baseline), aiming for >85% sleep efficiency, with weekly adjustments of 15-20 minutes based on performance. 1
- Cognitive restructuring: Address maladaptive beliefs about sleep, such as "I can't sleep without medication" or "My life will be ruined if I can't sleep." 1
- Relaxation techniques: Progressive muscle relaxation, guided imagery, or diaphragmatic breathing to reduce somatic and cognitive arousal. 1
- Sleep hygiene optimization: Avoid caffeine after early afternoon, eliminate evening alcohol, avoid late exercise, keep bedroom cool/dark/quiet, maintain regular wake time. 1, 2
CBT-I can be delivered through individual therapy, group sessions, telephone-based programs, web-based modules, or self-help books—all formats show effectiveness. 1, 2
Pharmacotherapy: When and What to Prescribe
Decision to Add Medication
Use shared decision-making to add pharmacotherapy only if CBT-I alone is unsuccessful or if daytime impairment is severe. 1 The American College of Physicians provides a weak recommendation (low-quality evidence) for adding short-term pharmacotherapy after CBT-I failure. 1
First-Line Medication Options for a 32-Year-Old
For this patient with both anxiety and insomnia, the treatment algorithm differs from primary insomnia:
Option 1: Short/intermediate-acting benzodiazepine receptor agonists (BzRAs)
- Eszopiclone 2-3 mg: Effective for both sleep onset and sleep maintenance insomnia. 2, 3
- Zolpidem 10 mg: Effective for both sleep onset and maintenance, with extensive evidence base showing decreased sleep latency for up to 35 days. 2, 3
- Zaleplon 10 mg: Specifically for sleep onset insomnia only. 2
Option 2: Ramelteon 8 mg (melatonin receptor agonist): Effective for sleep onset insomnia with minimal adverse effects and no abuse potential. 2
Option 3: Orexin receptor antagonists (suvorexant, lemborexant): Strong alternatives for sleep maintenance with different mechanism than BzRAs, reducing wake after sleep onset by 16-28 minutes. 2
Addressing the Comorbid Anxiety
The presence of anxiety changes the treatment algorithm. 1, 2 While sedating antidepressants are recommended when comorbid depression/anxiety exists, they are positioned as second or third-line options after BzRAs have failed. 1, 2
- Sedating antidepressants (trazodone, mirtazapine, doxepin, amitriptyline) may be considered if first-line BzRAs are unsuccessful AND the patient has comorbid depression or anxiety. 1
- However, trazodone is explicitly NOT recommended by the American Academy of Sleep Medicine for sleep onset or maintenance insomnia due to insufficient efficacy data. 2
- Low-dose doxepin 3-6 mg is recommended specifically for sleep maintenance insomnia, not sleep onset. 2
Critical Safety Considerations for Young Adults
- Start with the lowest effective dose for the shortest duration possible. 1
- All hypnotics carry FDA warnings about driving impairment, complex sleep behaviors (sleep-driving, sleep-walking), cognitive and behavioral changes. 1, 2
- Screen for substance use history: If present, avoid benzodiazepines and consider ramelteon or orexin antagonists instead. 2
- Assess for underlying sleep disorders: Rule out sleep apnea, restless legs syndrome, or delayed sleep phase syndrome before treating as primary insomnia. 2
- Pharmacotherapy should supplement, not replace, CBT-I: Continue behavioral interventions alongside any medication. 1, 2
Medications to Avoid
- Over-the-counter antihistamines (diphenhydramine, doxylamine): Not recommended due to lack of efficacy data, daytime sedation, and anticholinergic effects. 1, 2
- Herbal supplements (valerian) and melatonin: Not recommended due to insufficient evidence of efficacy. 1, 2
- Antipsychotics: Should not be used as first-line due to problematic metabolic side effects. 1
- Long-acting benzodiazepines (diazepam, clonazepam, lorazepam): Not recommended as first-line; reserved for specific situations where comorbid anxiety disorder requires treatment or after first-line options fail. 1, 2
Implementation Algorithm
- Initiate CBT-I immediately with all components (stimulus control, sleep restriction, cognitive restructuring, relaxation, sleep hygiene). 1, 2
- If severe daytime impairment or CBT-I insufficient after 4 weeks, add short-term pharmacotherapy:
- Continue CBT-I alongside medication—never use medication as monotherapy. 1, 2
- Reassess after 1-2 weeks: Evaluate efficacy on sleep parameters and daytime functioning; monitor for adverse effects including morning sedation, cognitive impairment, complex sleep behaviors. 2
- If first-line BzRA unsuccessful, try alternative BzRA before considering sedating antidepressants. 1, 2
- Taper medication when conditions allow: CBT-I facilitates successful discontinuation. 2
Common Pitfalls to Avoid
- Failing to implement CBT-I before or alongside medication: Behavioral interventions provide more sustained effects than medication alone. 1, 2
- Using sedating antidepressants as first-line: These are second/third-line options reserved for treatment failures or comorbid depression. 1, 2
- Prescribing long-term without reassessment: FDA labeling indicates short-term use; few studies evaluated medications beyond 4 weeks. 1
- Overlooking substance use history: Benzodiazepines should be avoided in patients with substance abuse. 2
- Assuming sleep hygiene education alone will suffice: It must be combined with other CBT-I modalities for chronic insomnia. 2, 4
