From the Guidelines
Quetiapine (Seroquel) should not be used as a first-line treatment for insomnia due to its potential risks and side effects, and alternative treatments such as cognitive behavioral therapy for insomnia and sleep hygiene practices should be considered first. Quetiapine is not FDA-approved for insomnia but is sometimes prescribed off-label at low doses (25-100 mg) taken 30-60 minutes before bedtime. Patients should be monitored for side effects including morning drowsiness, dizziness, weight gain, metabolic changes, and potential cardiac effects. Before starting treatment, baseline measurements of weight, blood pressure, fasting blood glucose, and lipid panel should be obtained, with follow-up monitoring every 3-6 months. When counseling patients, emphasize that this medication may cause significant sedation, so they should not drive or operate machinery after taking it. Patients should be advised that quetiapine can cause weight gain and metabolic changes, and that it should not be abruptly discontinued as this may worsen insomnia. The medication works primarily by blocking histamine H1 receptors at low doses, producing sedation, while at higher doses it affects serotonin and dopamine receptors. According to the American Academy of Sleep Medicine guidelines 1, cognitive behavioral therapy for insomnia and sleep hygiene practices are recommended as first-line treatments for insomnia, and quetiapine is not recommended due to its potential risks and side effects. Additionally, the American College of Physicians guidelines 1 also recommend cognitive behavioral therapy for insomnia and sleep hygiene practices as first-line treatments for insomnia, and suggest that pharmacologic therapy, including quetiapine, should only be considered if these treatments are not effective.
Some key points to consider when prescribing quetiapine for insomnia include:
- Monitoring for side effects, including morning drowsiness, dizziness, weight gain, metabolic changes, and potential cardiac effects
- Obtaining baseline measurements of weight, blood pressure, fasting blood glucose, and lipid panel, with follow-up monitoring every 3-6 months
- Counseling patients on the potential risks and side effects of quetiapine, including significant sedation and the potential for weight gain and metabolic changes
- Considering alternative treatments, such as cognitive behavioral therapy for insomnia and sleep hygiene practices, before prescribing quetiapine.

From the Research
Dosing Guidelines for Quetiapine (Seroquel) for Insomnia
- The typical doses of quetiapine used for insomnia are less than the FDA-recommended dosage of 150-800 mg/day, with doses ranging from 25-200 mg/day 2.
- There is limited data to support the use of quetiapine for insomnia, and its use is not recommended due to potential safety concerns 2, 3.
Monitoring Guidelines for Quetiapine (Seroquel) for Insomnia
- Quetiapine is associated with weight gain and other metabolic effects, and its use should be monitored for adverse effects and abuse 4.
- Patients taking quetiapine for insomnia should be monitored for serious adverse events, including fatal hepatotoxicity, restless legs syndrome, akathisia, and weight gain 2.
Counseling Guidelines for Quetiapine (Seroquel) for Insomnia
- Patients should be counseled on the potential risks and benefits of using quetiapine for insomnia, including the limited efficacy data and potential adverse effects 3.
- Alternative treatments for insomnia, such as cognitive behavioral therapy for insomnia (CBT-I) and FDA-approved medications, should be discussed with patients 5, 6.
- Patients should be informed that quetiapine is not a first-line treatment for insomnia and that its use should be cautious and monitored closely 4, 2.
