About this condition
Anxiety and insomnia are closely linked: each makes the other worse, and both respond to similar treatments. Mild-to-moderate cases respond well to cognitive behavioural therapy (CBT) and lifestyle measures. Medication can be a useful adjunct or alternative for moderate-to-severe symptoms.
The main drug groups are SSRIs (long-term anxiety control), benzodiazepines (short-term anxiety or insomnia, dependence risk), Z-drugs (short-term insomnia), and beta-blockers (situational performance anxiety). Buspirone is a non-sedating non-addictive option for generalised anxiety.
Treatment options
SSRIs
Sertraline, escitalopram. First-line for generalised anxiety, panic and OCD. Takes 4–6 weeks for full effect.
Benzodiazepines
Z-drugs
Beta-blockers (off-label)
Propranolol. Useful for performance anxiety — controls physical symptoms (tremor, racing heart) without sedation.
Common questions
Will I become addicted to SSRIs?
SSRIs are not addictive but can cause discontinuation symptoms if stopped abruptly. Always taper under medical supervision.
Are sleep medicines safe long-term?
Most are not. Short-term use is fine; long-term use of Z-drugs and benzodiazepines is associated with dependence and rebound insomnia.
When should I see a doctor?
If anxiety or insomnia affects daily functioning, lasts more than a few weeks, or is accompanied by suicidal thoughts — seek help promptly.
