acute panic attack
reassurance
Provide reassurance that the symptoms are not dangerous and that the attack will subside soon.
Patients usually hyperventilate as part of the attack but subjectively experience this as shortness of breath; this should be explained to the patient and an emphasis placed on slowing the breathing.
Using a quiet room and support from a significant other are useful.
In the emergency department setting, benzodiazepines may sometimes be considered to terminate an acute attack, for example if the patient's agitation or anxiety is particularly severe.[4]Andrews G, Bell C, Boyce P, et al. Royal Australian and New Zealand College of Psychiatrists clinical practice guidelines for the treatment of panic disorder, social anxiety disorder and generalised anxiety disorder. Australian & New Zealand Journal of Psychiatry. 2018;52(12):1109-172. https://journals.sagepub.com/doi/full/10.1177/0004867418799453
panic disorder
cognitive behavioral therapy (CBT)
Treatment is individualized taking into account severity, potential adverse effects, past treatment history, patient preference, any comorbid disorders and treatment availability. As a general guide, for those with mild panic disorder, consider offering self-help or CBT alone initially. For those with panic disorder of moderate severity, consider offering CBT, an SSRI/SNRI, or a combination of CBT and medication. For those with severe panic disorder, consider offering both CBT and an SSRI/SNRI from the offset.[4]Andrews G, Bell C, Boyce P, et al. Royal Australian and New Zealand College of Psychiatrists clinical practice guidelines for the treatment of panic disorder, social anxiety disorder and generalised anxiety disorder. Australian & New Zealand Journal of Psychiatry. 2018;52(12):1109-172. https://journals.sagepub.com/doi/full/10.1177/0004867418799453
CBT may be delivered face-to-face (individual or group) or as digital CBT (dCBT) accessed by computer, tablet or smartphone application. dCBT may be considered as an equal first-line option to face-to-face CBT.[4]Andrews G, Bell C, Boyce P, et al. Royal Australian and New Zealand College of Psychiatrists clinical practice guidelines for the treatment of panic disorder, social anxiety disorder and generalised anxiety disorder. Australian & New Zealand Journal of Psychiatry. 2018;52(12):1109-172. https://journals.sagepub.com/doi/full/10.1177/0004867418799453 dCBT courses may be integrated with face-to-face therapy, and may be supervised by a clinician or completed on a self-help basis. Guided dCBT is generally more effective than unguided dCBT; this involves regular help and contact to complete the course, although this does not necessarily have to be from a clinician.[4]Andrews G, Bell C, Boyce P, et al. Royal Australian and New Zealand College of Psychiatrists clinical practice guidelines for the treatment of panic disorder, social anxiety disorder and generalised anxiety disorder. Australian & New Zealand Journal of Psychiatry. 2018;52(12):1109-172. https://journals.sagepub.com/doi/full/10.1177/0004867418799453
CBT for panic disorder involves a combination of education, self-monitoring, relaxation training, challenging negative styles of thinking, situational exposure training, and systematic exposure to uncomfortable physical sensations. CBT can be used alone without pharmacotherapy, or may be used as an adjunct to any form of pharmacotherapy.[93]Hofmann SG, Sawyer AT, Korte KJ, et al. Is it beneficial to add pharmacotherapy to cognitive-behavioral therapy when treating anxiety disorders? A meta-analytic review.

It is an effective first-line treatment.[95]Barlow DH, Gorman JM, Shear MK, et al. Cognitive-behavioral therapy, imiprimine, or their combination for panic disorder: a randomized controlled trial. JAMA. 2000 May 17;283(19):2529-36.

What are the benefits and harms of psychological therapies in adults with panic disorder?/cca.html?targetUrl=https://cochranelibrary.com/cca/doi/10.1002/cca.1378/fullShow me the answer[Evidence C]a43d0d12-e049-406f-9978-3e627399ef55ccaCWhat are the benefits and harms of psychologic therapies in adults with panic disorder? Patients with anxiety disorders (including panic disorder) who are treated with CBT experience significant improvements in symptoms during the 24 months following completion of treatment.[153]Bandelow B, Sagebiel A, Belz M, et al. Enduring effects of psychological treatments for anxiety disorders: meta-analysis of follow-up studies. Br J Psychiatry. 2018 Jun;212(6):333-8.
http://www.ncbi.nlm.nih.gov/pubmed/29706139?tool=bestpractice.com
Treatment sessions may continue for 12 to 14 visits, although 6 to 7 sessions have also been found to be effective.[105]Marchand A, Roberge P, Primiano S, et al. A randomized, controlled clinical trial of standard, group and brief cognitive-behavioral therapy for panic disorder with agoraphobia: a two-year follow-up. J Anxiety Disord. 2009 Dec;23(8):1139-47.
http://www.ncbi.nlm.nih.gov/pubmed/19709851?tool=bestpractice.com
A referral to a mental health professional with expertise in CBT is recommended. The referring physician and mental health professional should maintain routine collaboration. Evidence also suggests that CBT delivery is beneficial in primary care settings.[81]Roy-Byrne P, Craske MG, Sullivan G, et al. Delivery of evidence-based treatment for multiple anxiety disorders in primary care: a randomized controlled trial. JAMA. 2010 May 19;303(19):1921-8.

Exposure therapy involves gradually increasing the patient's tolerance to previously avoided situations. The goal is to have the patient approach fear-provoking situations and sensations without engaging in escape or avoidance behavior or relying on safety cues. Repeated, frequent, controllable, and predictable exposures are associated with optimal outcomes.
SSRIs or SNRIs
Selective serotonin-reuptake inhibitors (SSRIs) are regarded as the optimal class of antidepressants given their broad spectrum of action and improved safety and tolerance.[116]Bakker A, van Balkom AJ, Stein DJ. Evidence-based pharmacotherapy of panic disorder. Int J Neuropsychopharmacol. 2005 Sep;8(3):473-82. http://www.ncbi.nlm.nih.gov/pubmed/15804373?tool=bestpractice.com [118]Batelaan NM, Van Balkom AJ, Stein DJ.

Pharmacological treatments for panic disorder, generalized anxiety disorder, specific phobia, and social anxiety disorder. In: Nathan PE, Gorman JM, eds. A guide to treatments that work. 4th ed. New York, NY: Oxford University Press; 2015:463-506.
Paroxetine is the least stimulating and most sedating of the SSRIs. Fluoxetine has a long half-life and therefore a lower risk of withdrawal symptoms, but it is more stimulating and requires slower titration.
Serotonin-norepinephrine reuptake inhibitors (SNRIs) such as venlafaxine are also effective.
Patients with anxiety disorders may be more susceptible to medication adverse effects; it is therefore advisable to start at the lowest dose and increase the dose with caution ("start low, go slow").[12]Penninx BW, Pine DS, Holmes EA, et al. Anxiety disorders. Lancet. 2021 Mar 6;397(10277):914-27. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9248771 http://www.ncbi.nlm.nih.gov/pubmed/33581801?tool=bestpractice.com Most adverse effects are time-limited during dose titration, and these should be discussed in advance with patients and monitored closely to ensure adherence.
Primary options
paroxetine: 5-10 mg orally (immediate release) once daily initially, increase by 10 mg/day increments every 7 days according to response, maximum 60 mg/day
OR
sertraline: 25 mg orally once daily initially, increase by 25-50 mg/day increments every 7 days according to response, maximum 200 mg/day
OR
fluoxetine: 5-10 mg orally (immediate release) once daily initially, increase by 10-20 mg/day increments every 4 weeks according to response, maximum 80 mg/day
OR
fluvoxamine: 25-50 mg orally (immediate release) once daily initially, increase by 25-50 mg/day every 4-7 days according to response, maximum 300 mg/day
OR
citalopram: 5-10 mg orally once daily initially, increase by 10-20 mg/day increments every 7 days according to response, maximum 40 mg/day
OR
escitalopram: 5 mg orally once daily initially, increase by 5-10 mg/day increments every 4 weeks according to response, maximum 20 mg/day
OR
venlafaxine: 37.5 mg orally (extended release) once daily initially, increase by 37.5 to 75 mg/day increments every 7 days according to response, maximum 225 mg/day
psychoeducation and lifestyle advice
Treatment recommended for ALL patients in selected patient group
Offer psychoeducation as soon as a diagnosis has been made.[12]Penninx BW, Pine DS, Holmes EA, et al. Anxiety disorders. Lancet. 2021 Mar 6;397(10277):914-27. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9248771 http://www.ncbi.nlm.nih.gov/pubmed/33581801?tool=bestpractice.com A key part of any treatment approach is information and education about the nature of panic and anxiety. In particular, panic is an understandable reaction to perceived danger (the "fight or flight" response). Fear arises from the misinterpretation of normal body sensations. Drawing a simple diagram together with the person - linking symptoms, interpretation, anxiety with arrows in a "vicious circle" - can be helpful. It is important for the person to appreciate that the first goal of treatment is not to remove all anxiety, only to manage it successfully. Attempts by the person to cope (e.g., by avoidance or safety seeking) are understandable, but inadvertently lead to maintaining the problem.
Advice on lifestyle factors includes: good sleep; regular exercise; reduced use of caffeine, tobacco, and alcohol; healthy diet; and staying engaged with meaningful activities and healthy social supports.[4]Andrews G, Bell C, Boyce P, et al. Royal Australian and New Zealand College of Psychiatrists clinical practice guidelines for the treatment of panic disorder, social anxiety disorder and generalised anxiety disorder. Australian & New Zealand Journal of Psychiatry. 2018;52(12):1109-172. https://journals.sagepub.com/doi/full/10.1177/0004867418799453
cognitive behavioral therapy (CBT)
Treatment recommended for SOME patients in selected patient group
Increased medication adherence and response rates, with a reduction in the amount of medication required to gain symptom control, are observed with adjunctive CBT.[93]Hofmann SG, Sawyer AT, Korte KJ, et al. Is it beneficial to add pharmacotherapy to cognitive-behavioral therapy when treating anxiety disorders? A meta-analytic review.

CBT for panic disorder involves a combination of education, self-monitoring, relaxation training, challenging negative styles of thinking, situational exposure training, and systematic exposure to uncomfortable physical sensations.
Exposure therapy involves gradually increasing the patient's tolerance to previously avoided situations. The goal is to have the patient stay in the feared situation long enough to allow fear reduction to occur without engaging in escape or avoidance behavior or relying on safety cues. Repeated, frequent, controllable, and predictable exposures are associated with optimal outcomes.
benzodiazepines
Treatment recommended for SOME patients in selected patient group
Benzodiazepines are not recommended for patients with panic disorder by some international guidelines, e.g., those from the UK National Institute for Health and Care Excellence, due to concerns about negative long-term outcomes.[69]National Institute for Health and Care Excellence. Generalised anxiety disorder and panic disorder in adults: management. Jun 2020 [internet publication]. https://www.nice.org.uk/guidance/CG113 However cautious short-term use of benzodiazepines is recommended by other guidelines as a second-line option for selected patients with panic disorders.[4]Andrews G, Bell C, Boyce P, et al. Royal Australian and New Zealand College of Psychiatrists clinical practice guidelines for the treatment of panic disorder, social anxiety disorder and generalised anxiety disorder. Australian & New Zealand Journal of Psychiatry. 2018;52(12):1109-172. https://journals.sagepub.com/doi/full/10.1177/0004867418799453 [70]Katzman MA, Bleau P, Blier P, et al; Canadian Anxiety Guidelines Initiative Group on behalf of the Anxiety Disorders Association of Canada and McGill University.

Benzodiazepines are recommended for short-term use only (e.g., 2 to 4 weeks).[134]Royal Australian College of General Practitioners. Prescribing drugs of dependence in general practice, Part B - benzodiazepines. Jun 2015 [internet publication]. https://www.racgp.org.au/FSDEDEV/media/documents/Clinical%20Resources/Guidelines/Drugs%20of%20dependence/Prescribing-drugs-of-dependence-in-general-practice-Part-B-Benzodiazepines.pdf
Benzodiazepines may be used for some patients as an adjunctive treatment to achieve a rapid reduction in panic attacks during the initial titration of a selective serotonin-reuptake inhibitor.[4]Andrews G, Bell C, Boyce P, et al.

If benzodiazepines are indicated, the preference may be for scheduled, longer-acting agents so that medication use is time-dependent rather than response/panic-dependent. "As needed" use of short-acting benzodiazepines may result in the patient developing psychological dependence on these medications, which could diminish the ability for an individual to develop an internal locus of control over these symptoms.
Long-term treatment with benzodiazepines should be rare, supervised, made with caution and based on careful consideration of the anticipated risks and benefits of benzodiazepines for the individual patient; specialist input (e.g., from a psychiatrist or addiction specialist) is advisable. Patients using benzodiazepines long-term should be regularly offered the opportunity to gradually withdraw from long-term use; treatment at the lowest effective dose is recommended.[134]Royal Australian College of General Practitioners. Prescribing drugs of dependence in general practice, Part B - benzodiazepines. Jun 2015 [internet publication]. https://www.racgp.org.au/FSDEDEV/media/documents/Clinical%20Resources/Guidelines/Drugs%20of%20dependence/Prescribing-drugs-of-dependence-in-general-practice-Part-B-Benzodiazepines.pdf [137]Kennedy KM, O'Riordan J.

Abrupt discontinuation or rapid tapering schedules can increase risk for withdrawal symptoms.
Primary options
clonazepam: 0.25 mg orally twice daily initially, increase by 0.25 to 0.5 mg/day increments every 3 days according to response, maximum 4 mg/day
Secondary options
alprazolam: 0.25 to 0.5 mg orally (immediate release) four times daily initially, increase by 1 mg/day increments every 3-4 days according to response, maximum 6 mg/day
OR
lorazepam: 0.5 mg orally three times daily initially, increase gradually according to response, maximum 6 mg/day
OR
diazepam: 2.5 mg orally (immediate release) twice daily initially, increase gradually according to response, maximum 40 mg/day
tricyclic antidepressants (TCAs)
TCAs are indicated in patients for whom treatment with one or more selective serotonin-reuptake inhibitors (SSRIs) has failed, or in patients with neuropathic pain.
They are less favorable with respect to adverse effects and may not be as well tolerated as SSRIs.[123]Kimmel RJ, Roy-Byrne PP, Cowley DS. Pharmacological treatments for panic disorder, generalized anxiety disorder, specific phobia, and social anxiety disorder. In: Nathan PE, Gorman JM, eds. A guide to treatments that work. 4th ed. New York, NY: Oxford University Press; 2015:463-506.
Serum imipramine levels may need to be monitored closely due to the relatively narrow therapeutic index.
Primary options
imipramine: 10-25 mg orally once daily initially, increase by 10 mg/day increments every 2-4 days according to response, maximum 300 mg/day
OR
clomipramine: 12.5 to 25 mg orally once daily initially, increase gradually according to response, maximum 250 mg/day

CBT for panic disorder involves a combination of education, self-monitoring, relaxation training, challenging negative styles of thinking, situational exposure training, and systematic exposure to uncomfortable physical sensations.
Exposure therapy involves gradually increasing the patient's tolerance to previously avoided situations. The goal is to have the patient stay in the feared situation long enough to allow fear reduction to occur without engaging in escape or avoidance behavior or relying on safety cues. Repeated, frequent, controllable, and predictable exposures are associated with optimal outcomes.
benzodiazepines
Some clinicians may consider offering benzodiazepine monotherapy to patients with panic disorder with a history of intolerance or poor response to antidepressants.
Benzodiazepines are not recommended for panic disorder by some international guidelines, e.g., those from the UK National Institute for Health and Care Excellence, due to concerns about negative long-term outcomes.[69]National Institute for Health and Care Excellence. Generalised anxiety disorder and panic disorder in adults: management. Jun 2020 [internet publication]. https://www.nice.org.uk/guidance/CG113 However cautious short-term use of benzodiazepines is recommended by other guidelines as an alternative option for selected patients with panic disorders for example for patients whose symptoms have not responded to other treatments.[4]Andrews G, Bell C, Boyce P, et al. Royal Australian and New Zealand College of Psychiatrists clinical practice guidelines for the treatment of panic disorder, social anxiety disorder and generalised anxiety disorder.

Benzodiazepines have a rapid onset of action and are generally well tolerated, although physiologic dependence can occur in as little as 2 to 4 weeks.[146]Bystritsky A.

If benzodiazepines are indicated, the preference may be for scheduled, longer-acting agents so that medication use is time-dependent rather than response/panic-dependent. "As needed" use of short-acting benzodiazepines may result in the patient developing psychological dependence on these medications, which could diminish the ability for an individual to develop an internal locus of control over these symptoms.
Long-term treatment with benzodiazepines should be rare, supervised, made with caution and based on careful consideration of the anticipated risks and benefits of benzodiazepines for the individual patient; specialist input (e.g., from a psychiatrist or addiction specialist) is advisable. Patients using benzodiazepines long-term should be regularly offered the opportunity to gradually withdraw from long-term use; treatment at the lowest effective dose is recommended.[134]Royal Australian College of General Practitioners. Prescribing drugs of dependence in general practice, Part B - benzodiazepines. Jun 2015 [internet publication]. https://www.racgp.org.au/FSDEDEV/media/documents/Clinical%20Resources/Guidelines/Drugs%20of%20dependence/Prescribing-drugs-of-dependence-in-general-practice-Part-B-Benzodiazepines.pdf [137]Kennedy KM, O'Riordan J.

Abrupt discontinuation or rapid tapering schedules can increase risk for withdrawal symptoms.

psychoeducation and lifestyle advice
Treatment recommended for ALL patients in selected patient group
Offer psychoeducation as soon as a diagnosis has been made.[12]Penninx BW, Pine DS, Holmes EA, et al. Anxiety disorders. Lancet. 2021 Mar 6;397(10277):914-27. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9248771 http://www.ncbi.nlm.nih.gov/pubmed/33581801?tool=bestpractice.com A key part of any treatment approach is information and education about the nature of panic and anxiety. In particular, panic is an understandable reaction to perceived danger (the "fight or flight" response). Fear arises from the misinterpretation of normal body sensations. Drawing a simple diagram together with the person - linking symptoms, interpretation, anxiety with arrows in a "vicious circle" - can be helpful. It is important for the person to appreciate that the first goal of treatment is not to remove all anxiety, only to manage it successfully. Attempts by the person to cope (e.g., by avoidance or safety seeking) are understandable, but inadvertently lead to maintaining the problem.
Advice on lifestyle factors includes: good sleep; regular exercise; reduced use of caffeine, tobacco, and alcohol; healthy diet; and staying engaged with meaningful activities and healthy social supports.[4]Andrews G, Bell C, Boyce P, et al.

SSRIs or SNRIs
Selective serotonin-reuptake inhibitors (SSRIs) are regarded as the optimal class of antidepressants given their broad spectrum of action and improved safety and tolerance.[116]Bakker A, van Balkom AJ, Stein DJ. Evidence-based pharmacotherapy of panic disorder. Int J Neuropsychopharmacol. 2005 Sep;8(3):473-82. http://www.ncbi.nlm.nih.gov/pubmed/15804373?tool=bestpractice.com [118]Batelaan NM, Van Balkom AJ, Stein DJ.

New York, NY: Oxford University Press; 2015:463-506.
Paroxetine is the least stimulating and most sedating of the SSRIs. Fluoxetine has a long half-life and therefore a lower risk of withdrawal symptoms, but it is more stimulating and requires slower titration.
Serotonin-norepinephrine reuptake inhibitors (SNRIs) such as venlafaxine are also effective.
Patients with anxiety disorders may be more susceptible to medication adverse effects; it is therefore advisable to start at the lowest dose and increase the dose with caution ("start low, go slow").[12]Penninx BW, Pine DS, Holmes EA, et al. Anxiety disorders. Lancet. 2021 Mar 6;397(10277):914-27. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9248771 http://www.ncbi.nlm.nih.gov/pubmed/33581801?tool=bestpractice.com Most adverse effects are time-limited during dose titration, and these should be discussed in advance with patients and monitored closely to ensure adherence.
Primary options
paroxetine: 5-10 mg orally (immediate release) once daily initially, increase by 10 mg/day increments every 7 days according to response, maximum 60 mg/day
OR

The goal is to have the patient stay in the feared situation long enough to allow fear reduction to occur without engaging in escape or avoidance behavior or relying on safety cues. Repeated, frequent, controllable, and predictable exposures are associated with optimal outcomes.
tricyclic antidepressants (TCAs)
TCAs are indicated in patients for whom treatment with one or more SSRI/SNRIs or CBT has failed, or in patients with neuropathic pain.
They are less favorable with respect to adverse effects and may not be as well tolerated as SSRIs.[123]Kimmel RJ, Roy-Byrne PP, Cowley DS. Pharmacological treatments for panic disorder, generalized anxiety disorder, specific phobia, and social anxiety disorder. In: Nathan PE, Gorman JM, eds. A guide to treatments that work. 4th ed. New York, NY: Oxford University Press; 2015:463-506.
Serum imipramine levels may need to be monitored closely due to the relatively narrow therapeutic index.
Primary options
imipramine: 10-25 mg orally once daily initially, increase by 10 mg/day increments every 2-4 days according to response, maximum 300 mg/day
OR
clomipramine: 12.5 to 25 mg orally once daily initially, increase gradually according to response, maximum 250 mg/day

Lancet. 2021 Mar 6;397(10277):914-27. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9248771 http://www.ncbi.nlm.nih.gov/pubmed/33581801?tool=bestpractice.com A key part of any treatment approach is information and education about the nature of panic and anxiety. In particular, panic is an understandable reaction to perceived danger (the "fight or flight" response). Fear arises from the misinterpretation of normal body sensations. Drawing a simple diagram together with the person - linking symptoms, interpretation, anxiety with arrows in a "vicious circle" - can be helpful. It is important for the person to appreciate that the first goal of treatment is not to remove all anxiety, only to manage it successfully. Attempts by the person to cope (e.g., by avoidance or safety seeking) are understandable, but inadvertently lead to maintaining the problem.
Advice on lifestyle factors includes: good sleep; regular exercise; reduced use of caffeine, tobacco, and alcohol; healthy diet; and staying engaged with meaningful activities and healthy social supports.[4]Andrews G, Bell C, Boyce P, et al.

cognitive behavioral therapy (CBT)

CBT may be delivered face-to-face (individual or group) or as digital CBT (dCBT) accessed by computer, tablet or smartphone application. dCBT may be considered as an equal first-line option to face-to-face CBT.[4]Andrews G, Bell C, Boyce P, et al.

Guided dCBT is generally more effective than unguided dCBT; this involves regular help and contact to complete the course, although this does not necessarily have to be from a clinician.[4]Andrews G, Bell C, Boyce P, et al.

CBT for panic disorder involves a combination of education, self-monitoring, relaxation training, challenging negative styles of thinking, situational exposure training, and systematic exposure to uncomfortable physical sensations.
Exposure therapy involves gradually increasing the patient's tolerance to previously avoided situations. The goal is to have the patient stay in the feared situation long enough to allow fear reduction to occur without engaging in escape or avoidance behavior or relying on safety cues. Repeated, frequent, controllable, and predictable exposures are associated with optimal outcomes.
dual pharmacotherapy
Guidelines from the STAR*D study for treatment-resistant comorbid depression recommend dual pharmacotherapy in non-responding patients if they show a partial response (25% improvement in symptoms) with a maximum dose of 1 antidepressant.[143]Rush AJ. STAR*D: what have we learned? Am J Psychiatry. 2007 Feb;164(2):201-4. http://www.ncbi.nlm.nih.gov/pubmed/17267779?tool=bestpractice.com
Combining 2 drugs from groups with different mechanisms of action may be considered, the groups being selective serotonin-reuptake inhibitors (paroxetine, sertraline, fluoxetine, fluvoxamine, citalopram, escitalopram), serotonin-norepinephrine reuptake inhibitors (venlafaxine), mirtazapine, and tricyclic antidepressants (imipramine, clomipramine).
Patients with anxiety disorders may be more susceptible to medication adverse effects; it is therefore advisable to start at the lowest dose and increase the dose with caution ("start low, go slow").

SSRIs or SNRIs
Selective serotonin-reuptake inhibitors (SSRIs) are regarded as the optimal class of antidepressants given their broad spectrum of action and improved safety and tolerance.[116]Bakker A, van Balkom AJ, Stein DJ. Evidence-based pharmacotherapy of panic disorder. Int J Neuropsychopharmacol. 2005 Sep;8(3):473-82. http://www.ncbi.nlm.nih.gov/pubmed/15804373?tool=bestpractice.com [118]Batelaan NM, Van Balkom AJ, Stein DJ.

New York, NY: Oxford University Press; 2015:463-506.
Paroxetine is the least stimulating and most sedating of the SSRIs. Fluoxetine has a long half-life and therefore a lower risk of withdrawal symptoms, but it is more stimulating and requires slower titration.
Serotonin-norepinephrine reuptake inhibitors (SNRIs) such as venlafaxine are also effective.
Patients with anxiety disorders may be more susceptible to medication adverse effects; it is therefore advisable to start at the lowest dose and increase the dose with caution ("start low, go slow").[12]Penninx BW, Pine DS, Holmes EA, et al.

benzodiazepines
Treatment recommended for SOME patients in selected patient group
Benzodiazepines are not recommended for patients with panic disorder by some international guidelines, e.g., those from the UK National Institute for Health and Care Excellence, due to concerns about negative long-term outcomes.[69]National Institute for Health and Care Excellence. Generalised anxiety disorder and panic disorder in adults: management.

If benzodiazepines are indicated, the preference may be for scheduled, longer-acting agents so that medication use is time-dependent rather than response/panic-dependent. "As needed" use of short-acting benzodiazepines may result in the patient developing psychological dependence on these medications, which could diminish the ability for an individual to develop an internal locus of control over these symptoms.
Long-term treatment with benzodiazepines should be rare, supervised, made with caution and based on careful consideration of the anticipated risks and benefits of benzodiazepines for the individual patient; specialist input (e.g., from a psychiatrist or addiction specialist) is advisable. Patients using benzodiazepines long-term should be regularly offered the opportunity to gradually withdraw from long-term use; treatment at the lowest effective dose is recommended.[134]Royal Australian College of General Practitioners.

Abrupt discontinuation or rapid tapering schedules can increase risk for withdrawal symptoms.
Primary options
clonazepam: 0.25 mg orally twice daily initially, increase by 0.25 to 0.5 mg/day increments every 3 days according to response, maximum 4 mg/day
Secondary options
alprazolam: 0.25 to 0.5 mg orally (immediate release) four times daily initially, increase by 1 mg/day increments every 3-4 days according to response, maximum 6 mg/day
OR
lorazepam: 0.5 mg orally three times daily initially, increase gradually according to response, maximum 6 mg/day
OR
diazepam: 2.5 mg orally (immediate release) twice daily initially, increase gradually according to response, maximum 40 mg/day
tricyclic antidepressants (TCAs)
TCAs are indicated in patients for whom treatment with one or more SSRI/SNRIs or CBT has failed, or in patients with neuropathic pain.
They are less favorable with respect to adverse effects and may not be as well tolerated as SSRIs.[123]Kimmel RJ, Roy-Byrne PP, Cowley DS. Pharmacological treatments for panic disorder, generalized anxiety disorder, specific phobia, and social anxiety disorder. In: Nathan PE, Gorman JM, eds. A guide to treatments that work. 4th ed. New York, NY: Oxford University Press; 2015:463-506.
Serum imipramine levels may need to be monitored closely due to the relatively narrow therapeutic index.
Primary options
imipramine: 10-25 mg orally once daily initially, increase by 10 mg/day increments every 2-4 days according to response, maximum 300 mg/day
OR
clomipramine: 12.5 to 25 mg orally once daily initially, increase gradually according to response, maximum 250 mg/day
psychoeducation and lifestyle advice
Treatment recommended for ALL patients in selected patient group
Offer psychoeducation as soon as a diagnosis has been made.[12]Penninx BW, Pine DS, Holmes EA, et al. Anxiety disorders. Lancet. 2021 Mar 6;397(10277):914-27. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9248771 http://www.ncbi.nlm.nih.gov/pubmed/33581801?tool=bestpractice.com A key part of any treatment approach is information and education about the nature of panic and anxiety. In particular, panic is an understandable reaction to perceived danger (the "fight or flight" response). Fear arises from the misinterpretation of normal body sensations. Drawing a simple diagram together with the person - linking symptoms, interpretation, anxiety with arrows in a "vicious circle" - can be helpful. It is important for the person to appreciate that the first goal of treatment is not to remove all anxiety, only to manage it successfully. Attempts by the person to cope (e.g., by avoidance or safety seeking) are understandable, but inadvertently lead to maintaining the problem.
Advice on lifestyle factors includes: good sleep; regular exercise; reduced use of caffeine, tobacco, and alcohol; healthy diet; and staying engaged with meaningful activities and healthy social supports.[4]Andrews G, Bell C, Boyce P, et al. Royal Australian and New Zealand College of Psychiatrists clinical practice guidelines for the treatment of panic disorder, social anxiety disorder and generalised anxiety disorder.

Guided dCBT is generally more effective than unguided dCBT; this involves regular help and contact to complete the course, although this does not necessarily have to be from a clinician.[4]Andrews G, Bell C, Boyce P, et al.

CBT for panic disorder involves a combination of education, self-monitoring, relaxation training, challenging negative styles of thinking, situational exposure training, and systematic exposure to uncomfortable physical sensations.
Exposure therapy involves gradually increasing the patient's tolerance to previously avoided situations. The goal is to have the patient stay in the feared situation long enough to allow fear reduction to occur without engaging in escape or avoidance behavior or relying on safety cues. Repeated, frequent, controllable, and predictable exposures are associated with optimal outcomes.
benzodiazepines
Some clinicians may consider offering benzodiazepine monotherapy to patients with panic disorder and comorbid anxiety with a history of intolerance to antidepressants. Benzodiazepines are not recommended for patients with panic disorder by some international guidelines, e.g., those from the UK National Institute for Health and Care Excellence, due to concerns about negative long-term outcomes.[69]National Institute for Health and Care Excellence. Generalised anxiety disorder and panic disorder in adults: management.

panic attacks without panic disorder
counseling and monitoring
Explain to patients that panic attacks affect up to one third of individuals in their lifetime but with less than 10% developing full panic disorder, and that although the attacks are uncomfortable, they are not dangerous and are time-limited.
Encourage patients to monitor the intensity, frequency, and duration of attacks, and whether the episodes are expected or unexpected.
Self-help materials based on principles of cognitive behavioral therapy are also beneficial. Bibliotherapy, either alone or in combination with brief phone contact, may be helpful in reducing panic-related symptoms.[87]Febbraro GA. An investigation into the effectiveness of bibliotherapy and minimal contact interventions in the treatment of panic attacks. J Clin Psychol. 2005 Jun;61(6):763-79. http://www.ncbi.nlm.nih.gov/pubmed/15546141?tool=bestpractice.com [88]Sharp DM, Power KG, Swanson V.
