Psychological therapies are integral to the successful treatment of these disorders and must be used in preference to drug treatments, but are beyond the scope of this guidance.
Drug treatment in adults should be considered if:
This guidance covers both GAD without additional psychiatric co-morbidity, and the more typical presentation of GAD comorbid with other anxiety and depressive disorders in which GAD is the primary diagnosis.
If the person has depression with anxiety symptoms follow the guidance on Unipolar Depression.
Antidepressants should be the only pharmacological intervention used in the longer-term management of generalised anxiety disorder.
Before prescribing consider the individual's age, previous treatment responses, risk of self-harm, possible interactions with pre-existing conditions and medicines, the individual's preference and, where all else is equal, cost.
Side effects (specifically initial increase in anxiety) on the initiation of antidepressants may be minimised by starting at a low dose and increasing the dose slowly until a satisfactory therapeutic response is achieved.
If the treatment is effective, advise the person to continue taking it for at least a year (as the likelihood of relapse is high).
Propranolol is not routinely recommended for generalised anxiety disorder.
(unlicensed indication)
If patient cannot tolerate an SSRI or SNRI consider offering pregabalin. The need for continued treatment should be reassessed regularly.

Psychological interventions should be considered first-line in patients with PTSD.
Short term use of hypnotic medication may be appropriate for management of sleep disturbance (see Insomnia section), but consider use of a suitable antidepressant at an early stage for longer term management.
Consider using a short course (maximum 2 weeks) of a benzodiazepine if an individual develops side effects such as acute anxiety, insomnia or agitation upon commencing an antidepressant (especially an SSRI). Take into account their risk of falls and avoid if chronic anxiety is present prior to commencing antidepressant or if they have a previous history of chemical addictive problems.
If an individual with post-traumatic stress disorder develops marked and/ or prolonged akathisia whilst taking an antidepressant drug, treatment should be reviewed.
Where an individual has responded well to the prescribed medication, treatment should be continued for at least 12 months.
