Panic disorder is a common condition associated with high medical service utilization. Naturalistic longitudinal studies indicate that the course of untreated panic disorder can be chronic and disabling.[29]Barlow DH. Anxiety and its disorders. 2nd ed. New York: Guilford Press; 2002. Relapse rates are higher among women than men.
Effective management of panic disorder requires early detection, education, and delivery of evidence-based pharmacotherapy and/or cognitive behavioral therapy (CBT). In a longitudinal study of CBT, 87% of patients were panic-free at the end of treatment, 96% remained in remission at 2-year follow-up, 77% at 5-year follow-up, and 67% after 7-year follow-up.[167]Fava GA, Zielezny M, Savron G, et al. Long-term effects of behavioural treatment for panic disorder with agoraphobia. Br J Psychiatry. 1995 Jan;166(1):87-92.

Other longitudinal studies of cognitive CBT suggest that many patients still experience ongoing panic symptoms across time, thereby necessitating additional monitoring.[168]Brown TA, Barlow DH. Long-term outcome in cognitive-behavioral treatment of panic disorder: clinical predictors and alternative strategies for assessment. J Consult Clin Psychol. 1995 Oct;63(5):754-65.

Relapse probability may be reduced through periodic "booster" exposure-based sessions.
Pharmacotherapy for panic disorder should be continued for at least 1 year from the point of treatment response, to help ensure symptom reduction and protection against relapse.[147]Batelaan NM, Bosman RC, Muntingh A, et al.

Relapse rates following medication discontinuation are estimated to be between 55% and 70%.[169]Ballenger JC, Pecknold J, Rickels K, et al. Medication discontinuation in panic disorder. J Clin Psychiatry. 1993 Oct;54 Suppl:15-21.

Discontinuing antidepressant medication is associated with moderate rates of relapse, and discontinuation of benzodiazepines is associated with a higher risk for relapse. There is evidence to suggest that CBT has an enduring positive effect for at least 12 months after treatment completion compared with control conditions.[152]van Dis EAM, van Veen SC, Hagenaars MA, et al. Long-term outcomes of Cognitive behavioral therapy for anxiety-related disorders: A systematic review and meta-analysis. JAMA Psychiatry. 2020 Mar 1;77(3):265-73.

Long-term management of panic disorder requires adequate dosing and attainment of maximal functioning before medication discontinuation.[170]Doyle A, Pollack MH. Long-term management of panic disorder. J Clin Psychiatry. 2004;65 Suppl 5:24-8.

Antidepressants combined with CBT may be indicated to manage relapse, with some patients remaining on maintenance pharmacotherapy and booster CBT sessions to protect against relapse over the longer term.[111]Furukawa TA, Watanabe N, Churchill R.
