What is the best medication for severe anxiety?

Best Medications for Severe Anxiety

For severe anxiety, selective serotonin reuptake inhibitors (SSRIs) and serotonin-norepinephrine reuptake inhibitors (SNRIs) are the first-line pharmacological treatments due to their established efficacy and favorable safety profiles. 1, 2

First-Line Medication Options

SSRIs (First Choice)

• Sertraline (Zoloft)
  • Starting dose: 25-50mg daily
  • Target dose: 50-200mg daily
  • FDA-approved for social anxiety disorder, panic disorder, and PTSD 3
  • Demonstrated efficacy in reducing panic attacks and anxiety symptoms 4
  • Well-tolerated with favorable side effect profile compared to other options 2

SNRIs (Alternative First-Line)

• Venlafaxine (Effexor XR)

  • Starting dose: 37.5mg daily
  • Target dose: 75-225mg daily
  • Particularly effective for social anxiety disorder 5, 6
  • Has a dose-dependent effect (higher doses provide more norepinephrine reuptake inhibition) 6
  • May cause blood pressure elevation at doses above 225mg daily 6

• Duloxetine (Cymbalta)

  • Starting dose: 30mg daily
  • Target dose: 60-120mg daily
  • Particularly useful when anxiety coexists with chronic pain 1
  • More balanced serotonin and norepinephrine reuptake inhibition (10:1 ratio) 6

Second-Line Options

Benzodiazepines

• Alprazolam (Xanax)
  • Effective for acute anxiety and panic disorder 7
  • Not recommended for routine or long-term use due to dependence and tolerance concerns 8
  • Should be reserved for short-term use during initiation of SSRIs/SNRIs when rapid symptom control is needed

Other Options

• Buspirone
  • Starting dose: 5mg twice daily
  • Maximum dose: 60mg daily
  • Alternative to benzodiazepines with lower abuse potential 1
  • Takes 2-4 weeks for full effect

Treatment Algorithm

1. Initial Assessment

   • Determine anxiety disorder subtype (generalized anxiety, social anxiety, panic disorder)
   • Screen for comorbid conditions (depression, substance use)
   • Assess suicide risk and severity of symptoms

2. First-Line Treatment

   • Start with SSRI (preferably sertraline) unless contraindicated
   • Begin with lower doses and titrate gradually
   • For severe symptoms requiring immediate relief, consider short-term (1-2 weeks) benzodiazepine adjunct

3. Monitoring and Dose Adjustment

   • Follow up within 1-2 weeks of medication initiation 1
   • Assess for side effects and symptom improvement
   • Titrate dose upward if needed (SSRIs show better response at higher doses) 9
   • Continue for at least 9-12 months after symptom remission 1

4. Alternative Approaches

   • If inadequate response to SSRI after 4-6 weeks at adequate dose, switch to SNRI
   • Consider cognitive behavioral therapy (CBT) as adjunct or alternative to medication 5, 1

Special Considerations

• Age-specific concerns

  • For older adults: Start with lower doses of SSRIs
  • For children/adolescents: SNRIs like duloxetine may be appropriate for anxiety disorders 5

• Medical comorbidities

  • Cardiovascular disease: Start sertraline at lower dose (25mg) and titrate slowly 1
  • Chronic pain: Consider duloxetine as first choice 1
  • Substance use history: Avoid benzodiazepines; consider buspirone 1

• Common pitfalls to avoid

  • Starting at too high a dose (increases side effects and reduces adherence)
  • Discontinuing medication too soon after symptom improvement
  • Abrupt discontinuation (taper gradually to prevent withdrawal)
  • Using benzodiazepines as long-term monotherapy

Non-Pharmacological Approaches

• Cognitive Behavioral Therapy (CBT)

  • Strongly recommended as first-line treatment or in combination with medication 5, 1
  • Individual CBT (12-20 sessions) has strongest evidence base 1
  • Can be delivered in group format or via internet with therapist support 5

• Self-help with CBT principles

  • Viable option for those who don't want face-to-face therapy 5
  • Can be used as adjunct to medication therapy

Remember that medication treatment should be continued for at least 9-12 months after symptom remission to prevent relapse, and discontinuation should always be done gradually to prevent withdrawal symptoms 1.
