Anxiety Treatment Options in Pocatello: From Therapy to Ketamine

By Kyle Roth, FNP-BC, APRN, MSN, MHA | Roth Family Medicine and Mental Health | Pocatello, Idaho

Anxiety disorders are the most common mental health conditions in the United States, affecting approximately 40 million adults — roughly 18% of the population. Yet despite their prevalence, anxiety disorders remain significantly undertreated: fewer than 37% of people with anxiety disorders receive treatment.

In Southeast Idaho, access to mental health care has historically been limited by geography and provider availability. At Roth Family Medicine and Mental Health, we offer a comprehensive range of evidence-based anxiety treatments — from first-line therapy and medication to advanced interventions including ketamine therapy for treatment-resistant cases.

This guide covers the full spectrum of anxiety treatment options, helping you understand what's available and what the evidence says about each approach.

Anxiety is not a single condition but a family of related disorders:

Generalized Anxiety Disorder (GAD): Persistent, excessive worry about multiple domains of life (work, health, finances, relationships) that is difficult to control and accompanied by physical symptoms (muscle tension, fatigue, sleep disruption, irritability).

Panic Disorder: Recurrent unexpected panic attacks — sudden surges of intense fear with physical symptoms (racing heart, shortness of breath, chest pain, dizziness) — accompanied by persistent worry about future attacks and behavioral changes to avoid them.

Social Anxiety Disorder: Intense fear of social situations due to concern about scrutiny, embarrassment, or humiliation. Often severely limits occupational and social functioning.

Specific Phobias: Intense, irrational fear of specific objects or situations (heights, flying, needles, animals).

Agoraphobia: Fear and avoidance of situations where escape might be difficult or help unavailable during a panic attack.

PTSD and OCD are classified separately from anxiety disorders in DSM-5 but share significant overlap and treatment approaches.

CBT is the gold standard psychotherapy for anxiety disorders, with the strongest evidence base of any psychological treatment. It works by identifying and modifying the cognitive distortions (catastrophic thinking, overestimation of threat, underestimation of coping ability) and behavioral patterns (avoidance) that maintain anxiety.

Response rates: 60–80% of patients with anxiety disorders show significant improvement with CBT.

Key components:

• Cognitive restructuring — identifying and challenging anxious thoughts
• Exposure therapy — systematic, graduated confrontation of feared situations
• Behavioral experiments — testing anxious predictions against reality
• Relaxation and mindfulness skills

Exposure therapy is the most powerful component of CBT for anxiety. Avoidance is the primary behavioral mechanism that maintains anxiety; exposure breaks the avoidance cycle and allows the brain to learn that feared situations are manageable.

Selective serotonin reuptake inhibitors (SSRIs) and serotonin-norepinephrine reuptake inhibitors (SNRIs) are the first-line medications for most anxiety disorders. They are effective, well-tolerated, and non-habit-forming.

Commonly used agents:

• Sertraline (Zoloft) — broad-spectrum, well-tolerated
• Escitalopram (Lexapro) — excellent tolerability, effective for GAD
• Venlafaxine (Effexor) — SNRI, effective for GAD, social anxiety, panic
• Duloxetine (Cymbalta) — SNRI, also addresses pain comorbidity
• Paroxetine (Paxil) — effective but more side effects

Important note: SSRIs/SNRIs take 4–6 weeks to produce full anxiolytic effects and may initially worsen anxiety in the first 1–2 weeks. Starting at low doses and titrating slowly reduces this effect.

Buspirone is a non-benzodiazepine anxiolytic that is particularly effective for GAD. It is non-habit-forming, does not cause sedation, and does not interact with alcohol. It requires 2–4 weeks to reach full effect.

Benzodiazepines (lorazepam, clonazepam, alprazolam, diazepam) produce rapid, potent anxiolytic effects through GABA-A receptor potentiation. They are effective for acute anxiety management but carry significant limitations:

• Tolerance and dependence develop with regular use
• Cognitive impairment — sedation, memory problems, psychomotor slowing
• Rebound anxiety on discontinuation
• Abuse potential — particularly in patients with substance use history
• Interaction with alcohol and opioids — potentially fatal respiratory depression

Current guidelines recommend benzodiazepines for short-term or as-needed use only, not as long-term maintenance treatment. For patients already on long-term benzodiazepines, a careful, gradual taper is recommended.

Propranolol and other beta-blockers reduce the peripheral physical symptoms of anxiety (racing heart, tremor, sweating) without affecting the psychological experience. They are particularly useful for situational anxiety (performance anxiety, public speaking) taken as needed.

Hydroxyzine is an antihistamine with anxiolytic properties. It is non-habit-forming, produces rapid relief (within 30–60 minutes), and is useful for as-needed anxiety management without the dependence risk of benzodiazepines.

Mirtazapine is an antidepressant with significant anxiolytic properties, particularly useful when anxiety is accompanied by insomnia and appetite loss.

Emerging evidence supports ketamine's efficacy for anxiety disorders, particularly when anxiety co-occurs with treatment-resistant depression or PTSD. The proposed mechanisms include:

• Rapid restoration of prefrontal cortex function, which normally regulates amygdala reactivity
• Promotion of neuroplasticity in anxiety-relevant circuits
• Direct effects on glutamate signaling in the amygdala and prefrontal cortex

While the evidence base for anxiety is less mature than for depression, clinical experience and emerging research suggest meaningful benefit for patients with treatment-resistant anxiety, particularly GAD and social anxiety disorder.

TMS has demonstrated efficacy for anxiety disorders in several clinical trials, with protocols targeting the right dorsolateral prefrontal cortex (inhibitory stimulation) or the left DLPFC (excitatory stimulation). TMS is FDA-cleared for OCD and has off-label use for GAD and PTSD.

For patients with severe anxiety that has not responded to outpatient treatment, intensive outpatient programs provide structured, multi-hour daily treatment including CBT, group therapy, and medication management.

Regular aerobic exercise is one of the most effective anxiolytic interventions available. Multiple meta-analyses demonstrate that exercise reduces anxiety symptoms with effect sizes comparable to medication. The mechanisms include:

• Reduction of HPA axis reactivity
• Increased GABA and serotonin activity
• Promotion of neuroplasticity via BDNF
• Reduction of inflammatory markers
• Improved sleep quality

For anxiety, 30–45 minutes of moderate-intensity aerobic exercise 3–5 times per week is the evidence-based recommendation.

MBSR — an 8-week structured program combining mindfulness meditation, body scan, and yoga — has strong evidence for anxiety reduction. It works by training the capacity to observe anxious thoughts without being controlled by them.

Anxiety and sleep disruption are bidirectionally related. Addressing sleep disorders (particularly insomnia and sleep apnea) significantly reduces anxiety severity.

Caffeine is a direct anxiogenic — it activates the sympathetic nervous system and can trigger or worsen panic attacks. Alcohol, while acutely anxiolytic, produces rebound anxiety and disrupts sleep, worsening anxiety over time.

At Roth Family Medicine and Mental Health, we offer comprehensive anxiety evaluation and treatment including:

• Thorough diagnostic assessment
• Medication management (SSRIs, SNRIs, buspirone, and others)
• Coordination with therapy providers
• Ketamine therapy for treatment-resistant anxiety
• Functional medicine evaluation for anxiety contributors (thyroid, adrenal, nutritional)
• Referral for TMS when appropriate

We serve patients throughout Southeast Idaho including Pocatello, Chubbuck, Blackfoot, American Falls, and surrounding communities.

How do I know if I need medication or therapy? Both are effective, and the combination is often more effective than either alone. For mild-moderate anxiety, therapy alone may be sufficient. For moderate-severe anxiety, medication can reduce symptoms enough to engage effectively in therapy. We discuss the options and your preferences during the evaluation.

How long does anxiety treatment take? CBT for anxiety typically requires 12–20 sessions. Medication effects are typically seen within 4–8 weeks. Many patients achieve significant improvement within 3–6 months of starting treatment.

Is anxiety treatable without medication? Yes — CBT, exercise, mindfulness, and lifestyle interventions can produce significant anxiety reduction without medication. However, for moderate-severe anxiety, medication often accelerates and deepens the response to therapy.
