Best Medications for Generalized Anxiety Disorder in Adults

Start with either escitalopram 10 mg daily or sertraline 25-50 mg daily as first-line pharmacotherapy for generalized anxiety disorder, as SSRIs and SNRIs are the recommended first-line treatments with established efficacy and favorable safety profiles. 1, 2

First-Line Pharmacological Options

Preferred SSRIs

  • Escitalopram is a top-tier first-line agent, starting at 5-10 mg daily and titrating by 5-10 mg increments every 1-2 weeks to a target dose of 10-20 mg/day. 1, 2, 3

    • Demonstrated efficacy in three 8-week placebo-controlled trials specifically for GAD, showing statistically significant improvement on the Hamilton Anxiety Scale. 3
    • Lower risk of discontinuation symptoms compared to other SSRIs. 1
    • Preferred for elderly patients due to lower potential for drug interactions. 1

  • Sertraline is equally preferred as first-line, starting at 25-50 mg daily and titrating by 25-50 mg increments every 1-2 weeks to a target dose of 50-200 mg/day. 2

    • Also preferred for elderly patients with favorable drug interaction profile. 1

Alternative First-Line: SNRIs

  • Venlafaxine extended-release (75-225 mg/day) is suggested as an alternative first-line option with similar efficacy to SSRIs. 1, 2

    • Requires careful titration and blood pressure monitoring due to risk of sustained hypertension. 2
    • Higher risk of discontinuation symptoms compared to SSRIs. 2

  • Duloxetine (60-120 mg/day) has demonstrated efficacy in GAD and provides additional benefits for patients with comorbid pain conditions. 2

    • Start at 30 mg daily for one week to reduce nausea, then increase to 60 mg. 2

SSRIs to Use Cautiously

  • Paroxetine and fluvoxamine are effective but carry higher risks of discontinuation symptoms and should be reserved for when first-tier SSRIs fail. 1, 2
  • Paroxetine should be avoided in older adults due to higher rates of adverse effects. 1

Expected Response Timeline

  • Statistically significant improvement may begin by week 2, with clinically significant improvement expected by week 6, and maximal therapeutic benefit achieved by week 12 or later. 2
  • SSRI response follows a logarithmic model with diminishing returns at higher doses. 2
  • Do not abandon treatment prematurely; full response may take 12+ weeks. 2

Second-Line Options

  • Pregabalin or gabapentin can be considered when first-line treatments are ineffective or not tolerated, particularly for patients with comorbid pain conditions. 2

Treatment Duration

  • For a first episode of GAD, continue pharmacological treatment for at least 4-12 months after symptom remission. 1
  • For recurrent anxiety, longer-term or indefinite treatment may be beneficial. 1
  • Discontinue medication gradually to avoid withdrawal symptoms, particularly with shorter half-life SSRIs. 2, 3

Common Side Effects to Monitor

  • Nausea, sexual dysfunction (particularly ejaculatory delay in males), headache, insomnia, dry mouth, diarrhea, somnolence, and dizziness. 2, 3
  • Most adverse effects emerge within the first few weeks and typically resolve with continued treatment. 2
  • Critical warning: Monitor for suicidal thinking and behavior, especially in the first months and following dose adjustments. 2

Combination with Psychotherapy

  • Combining medication with cognitive behavioral therapy (CBT) provides optimal outcomes, though there is insufficient evidence to make a formal recommendation regarding combined treatment. 1, 2
  • Individual CBT is prioritized over group therapy due to superior clinical effectiveness. 1, 2

Medications to Avoid

  • Tricyclic antidepressants should be avoided due to unfavorable risk-benefit profile, particularly cardiac toxicity. 2
  • Benzodiazepines should be reserved for short-term use only due to risks of dependence, tolerance, and withdrawal. 2

Management of Inadequate Response

  • If inadequate response after 8-12 weeks at therapeutic doses, switch to a different SSRI or SNRI. 2
  • Consider adding CBT if not already implemented. 2
  • Assess response using standardized anxiety rating scales such as the Hamilton Anxiety Scale (HAM-A). 2
