    • Monitor for adverse drug effects
      • Weekly monitoring for risk of suicidal ideation and self-harm in patients with social anxiety disorder who were given a selective serotonin reuptake inhibitor or serotonin and norepinephrine reuptake inhibitor
    • Monitor for response to therapy
  • Re-assess therapy every month thereafter
  • The benefits of cognitive-behavioral therapy are maintained over 1-5 years of follow-up

Panic Disorder

  • Provide frequent follow-up during 1st 3 months (acute phase) of therapy
  • For patients receiving pharmacological therapy, monitor for adverse effects and response to therapy
  • Re-assess therapy at 8- to 12-weeks intervals

Therapy Change

Generalized Anxiety Disorder

  • If results are unsatisfactory after 4-8 weeks of treatment, consider:
    • Expert referral
    • Dose increase
    • Adding drug from another therapeutic class
    • Change in therapeutic class
    • Adding psychotherapy

Panic Disorder

  • 12 week-treatment period is needed to assess efficacy
  • If results are unsatisfactory consider:
    • Different treatment
    • Adding psychotherapy/medication
    • Expert referral
    • Re-evaluating diagnosis

Social Anxiety Disorder

  • Treatment period of 12 weeks is needed to evaluate effectiveness
  • If results are unsatisfactory consider:
    • Switching to a different drug from the same class of 1st-line agents or changing to a 2nd-line agent
    • Switching to psychotherapy
    • Expert referral
    • Re-evaluating diagnosis

Long-Term Treatment

Generalized Anxiety Disorder

  • Patients who respond to a 12-week trial of treatment should continue to be monitored for 6 more months
    • Symptom remission and return to full functioning is the goal of therapy
    • Manage late-onset drug adverse effects
  • If the medication is effective, continue treatment for at least 1 year; likelihood of relapse is high
  • Once full function has returned, attempt to withdraw treatment
    • Careful medication taper may be attempted
    • If after 2 careful attempts to discontinue medications patient still experiences anxiety symptoms, consider longer-term maintenance

Panic Disorder

Patients receiving pharmacological therapy:

  • Continue to monitor patient
    • Symptom remission and return to full functioning is the goal of therapy
    • Manage late-onset drug adverse effects
  • General recommendation: Continue medication for >1 year to maintain symptom reduction and reduce the risk of recurrence
    • Attempt discontinuation after this time and maintain close follow-up
  • Relapse is common
    • Re-institution of medication seems to help

Patients receiving psychotherapy:

  • Frequency of visits may generally be decreased
    • Discontinue after several months
  • Adding psychosocial treatment, particularly cognitive-behavioral therapy, to pharmacological therapy may enhance long-term outcomes by reducing the likelihood of relapse when pharmacotherapy is stopped
    • Some studies show remission of several years is possible with cognitive-behavioral therapy; however, effectiveness of resuming cognitive-behavioral therapy for patients whose relapse has not been studied

Social Anxiety Disorder

  • Once medication has taken effect, in vivo exposure exercises may be initiated
  • Continue to monitor patient
    • Symptom remission and return to full functioning is the goal of therapy
    • Manage late-onset drug adverse effects
  • Continue therapy for 6-12 months
    • Attempt tapering and discontinuation after this time and maintain close follow-up
      • Should symptoms recur after drug has been stopped or dose has been lowered, consider a dose increase, drug reintroduction, or individual cognitive-behavioral therapy
