Management of Anxiety and Sleep Disturbances

Introduction to Treatment Options

• The American Academy of Sleep Medicine and the American Academy of Child and Adolescent Psychiatry recommend melatonin as a safe, non-habit forming option for initiating sleep, and SSRIs such as sertraline or fluoxetine as first-line treatments for anxiety disorders, with trazodone as an excellent option when both conditions coexist 1, 2

Pharmacological Interventions

• Melatonin is a safe and effective option for sleep initiation and maintenance, recommended by the American Academy of Sleep Medicine 1
• SSRIs, such as sertraline or fluoxetine, are first-line treatments for anxiety disorders, including generalized anxiety, panic disorder, and social anxiety, according to the American Academy of Child and Adolescent Psychiatry 2
• Trazodone (25-100 mg) is often used as a second-choice treatment after melatonin for sleep disturbances, as suggested by the American Academy of Sleep Medicine 1
• Antihistamines, such as hydroxyzine, can be used for short-term management of insomnia, but are not recommended for long-term use due to tolerance and anticholinergic effects, as noted by the American Academy of Sleep Medicine 1
• Benzodiazepines carry risks of respiratory depression, ataxia, excessive sedation, memory impairment, paradoxical disinhibition, and physical and psychological dependence, and should be avoided during pregnancy, according to the American Academy of Sleep Medicine 1
• Second-generation antipsychotics, such as quetiapine, have significant side effects, including metabolic syndrome, and should not be prescribed for sleep disturbances alone, as recommended by the American Academy of Sleep Medicine 1
• Low-dose trazodone (25-100 mg) at bedtime is recommended for targeted insomnia treatment in patients with anxiety and depression, due to its non-habit forming properties and ability to address both sleep initiation and maintenance 3
• Mirtazapine 7.5-30 mg at bedtime is an alternative option, particularly beneficial for patients with depression and anxiety, and has the added benefit of potentially augmenting antidepressant effects 3
• Low-dose quetiapine (2.5-5 mg) at bedtime is reserved for more treatment-resistant cases 3

Non-Pharmacological Interventions

• Cognitive Behavioral Therapy for Insomnia (CBT-I) is a first-line approach for chronic insomnia, particularly beneficial for patients with psychiatric disorders, as recommended by the National Comprehensive Cancer Network and the American Academy of Sleep Medicine 4, 5, 3
• Structured sleep hygiene education, including a regular sleep-wake schedule, morning or afternoon exercise, daytime exposure to bright light, and keeping the bedroom dark, quiet, and comfortable, is recommended 4
• The American College of Obstetricians and Gynecologists recommends non-pharmacological approaches as the first-line treatment for sleep disturbances during pregnancy, including regular morning or afternoon exercise, daytime exposure to bright light, and maintaining a regular sleep-wake schedule 5, 3

Monitoring and Follow-up

• Serum ferritin levels should be checked in individuals with restless sleep, as iron supplementation may improve symptoms even when blood levels are not low, as suggested by the American Academy of Sleep Medicine 1
• Sleep symptoms should be reassessed after 2 weeks of any intervention, and monitoring for daytime sedation is necessary, especially with medications like trazodone, using a validated sleep questionnaire to track progress 4, 5, 3
• Obstructive sleep apnea (OSA) and restless legs syndrome (RLS) should be ruled out, as they may present or worsen during pregnancy, and interventions such as polysomnography and checking ferritin levels can be helpful 5, 3
• If insomnia persists despite interventions, referral to a sleep specialist is warranted, and untreated severe insomnia itself may pose risks to maternal and fetal health, as noted by the American Academy of Sleep Medicine 6
• Consider reducing Bupropion dose or switching to a more sedating antidepressant like mirtazapine if sleep does not improve, and ensure Bupropion is taken in the morning only to avoid contributing to insomnia 3
• Polysomnography may be necessary to rule out primary sleep disorders like sleep apnea, or evaluate for restless leg syndrome if insomnia persists despite interventions 4
