First-Line Medication for Treating Anxiety

Rationale for SSRI Selection

SSRIs have fewer anticholinergic effects and better tolerability compared to tricyclic antidepressants, especially important for managing anxiety in patients, as recommended by the American Academy of Family Physicians 1

Sertraline is recommended as the preferred SSRI for anxiety treatment due to its more favorable drug interaction profile compared to other SSRIs, lower risk of discontinuation syndrome compared to paroxetine, and relatively favorable side effect profile, as suggested by the American Academy of Child and Adolescent Psychiatry 2

The American Academy of Child and Adolescent Psychiatry recommends starting with a low dose (25-50mg daily) of sertraline and gradually titrating upward as needed, with dose adjustments made at 1-2 week intervals due to sertraline's shorter half-life 2

Citalopram or escitalopram may be considered if sertraline is not tolerated, as they have the least effect on CYP450 isoenzymes and lower propensity for drug interactions, according to the American Academy of Child and Adolescent Psychiatry 2
Paroxetine should be avoided due to its higher risk of discontinuation syndrome, greater anticholinergic effects, and increased risk of suicidal thinking compared to other SSRIs, as noted by the American Academy of Child and Adolescent Psychiatry and the American Academy of Family Physicians [1] [2]

Benzodiazepines should not be used as first-line monotherapy due to the risk of dependence, as recommended by the American College of Physicians 3

The American Academy of Family Physicians recommends continuing treatment with sertraline for at least 4-12 months after symptom remission, and considering longer-term treatment for recurrent anxiety 1

The American Academy of Child and Adolescent Psychiatry warns about possible initial worsening of anxiety symptoms when starting SSRIs, and recommends avoiding abrupt discontinuation of sertraline to prevent discontinuation syndrome 2
