Sleep medication: when a psychiatrist recommends it

Sleep medication is among the most commonly sought and most commonly misused interventions in mental healthcare. Understanding which medications are appropriate for which sleep patterns, and which are commonly misused, supports an informed clinical decision.

The clinical principle

Sleep medication is appropriate when sleep disruption is severe, not responding to non-pharmacological intervention, and the medication is matched to the specific sleep problem and its underlying cause. It is not appropriate as a primary response to insomnia before the underlying cause has been identified.

Medication by clinical indication

Melatonin – for circadian disruption only

Appropriate for delayed sleep phase, shift work, and jet lag. Not effective for anxiety-driven insomnia, sleep maintenance insomnia, or non-restorative sleep. Systematically misused by adults taking it for anxiety-driven insomnia.

Sedating antidepressants – for longer-term use without dependence

Low-dose mirtazapine, trazodone, and doxepin work through histamine blockade or serotonergic mechanisms rather than the GABA pathway of benzodiazepines. They can be used longer-term without tolerance development and are appropriate when sleep medication is required beyond the short term, particularly when co-occurring depression or anxiety is present.

Z-drugs (zolpidem, zopiclone) – short-term only

Effective for acute insomnia management. Not appropriate for chronic insomnia: tolerance develops within weeks, they suppress restorative sleep stages, and discontinuation produces rebound insomnia that reinforces reliance. Significantly overprescribed for chronic insomnia in general practice.

Benzodiazepines – acute situations only

Effective short-term. Clinically inappropriate for chronic insomnia management due to tolerance, physical dependence, and rebound insomnia on discontinuation.

SSRIs and SNRIs – for anxiety or depression-driven insomnia

Not sleep medications in the traditional sense. They improve sleep by treating the underlying condition disrupting sleep architecture.

The psychiatrist's role

A psychiatrist prescribing for sleep evaluates what is driving the disruption, which medication is appropriate for that specific mechanism, the appropriate duration, and how the medication fits into a broader treatment plan that includes non-pharmacological approaches.

A psychiatric evaluation identifies what is actually driving the disruption.
