What is the best approach for smoking cessation in a patient with a history of anxiety and depression?

Smoking Cessation in Patients with Anxiety and Depression

For patients with anxiety and depression attempting smoking cessation, combine pharmacotherapy (either combination NRT or varenicline as first-line) with intensive behavioral therapy that specifically addresses mental health symptoms, as depression and anxiety are major causes of relapse and require specialized intervention. 1

Pharmacotherapy Selection

First-Line Options

Combination NRT (nicotine patch + short-acting form) or varenicline are the preferred primary therapies for at least 12 weeks. 1

• Combination NRT: 21 mg patch daily plus short-acting NRT (lozenge/gum/inhaler/nasal spray) for breakthrough cravings 1

  • Consider increasing patch dose to 35-42 mg if 21 mg is insufficient 1
  • Blood nicotine levels from NRT are significantly lower than from smoking, making toxicity rare even with combination therapy 1

• Varenicline: Start 1-2 weeks before quit date 1

  • Days 1-3: 0.5 mg once daily
  • Days 4-7: 0.5 mg twice daily
  • Weeks 2-12: 1 mg twice daily if tolerated 1

Critical Safety Consideration for Mental Health Patients

Monitor closely for worsening depression, anxiety, suicidal ideation, or behavioral changes with both varenicline and bupropion. 1, 2

• Varenicline carries warnings about neuropsychiatric symptoms including depression and suicidal behavior, though these are uncommon 1
• Bupropion has a black box warning for suicidal thoughts and behaviors, particularly in young adults, and requires monitoring for mood changes 2
• Postmarketing reports document serious neuropsychiatric events including mood changes, psychosis, hallucinations, aggression, anxiety, panic, and completed suicide 2
• Discontinue medication immediately if these symptoms emerge 1, 2

Alternative Pharmacotherapy

Bupropion ± NRT can be used as subsequent therapy if first-line options fail or are contraindicated, but requires heightened vigilance in patients with depression/anxiety. 1, 2

• Initiate 1-2 weeks before quit date 1
• Days 1-3: 150 mg once daily
• Days 4 onward: 150 mg twice daily 1
• Given the patient's existing anxiety and depression, bupropion should be used cautiously with close psychiatric monitoring 2

Behavioral Therapy Requirements

Intensive behavioral therapy is mandatory, not optional, for patients with mental health comorbidities, as depression and anxiety are the most common causes of smoking relapse. 1

Specialized Mental Health-Focused Approach

Refer to specialized smoking cessation programs with staff trained to treat mental health disorders, or to behavioral therapists with expertise in comorbid substance dependence and mental health conditions. 1

• Standard cessation programs may be inadequate for psychiatric patients due to their neuropsychological profile 3
• Programs must include specific interventions designed to ameliorate depression, anxiety, and stress 1

Session Structure

Provide at least 4 sessions of 10-30+ minutes each during the 12-week pharmacotherapy course, with the first session within 2-3 weeks of starting treatment. 1

• Longer, more frequent sessions produce higher success rates 1
• Sessions can be individual or group, in-person or by phone 1
• If intensive therapy is unavailable, deliver brief advice at minimum (3 minutes), which still produces measurable benefit 1

Core Behavioral Components

Therapy must address both smoking cessation and mental health symptom management through:

• Problem-solving skills and coping strategies for nicotine withdrawal symptoms (which peak at 1-2 weeks) 1
• Identifying smoking triggers specific to anxiety and depression episodes 1
• Stress management techniques, as stress is a primary relapse trigger in psychiatric populations 1
• Motivational interviewing using the four principles: express empathy, develop discrepancy, roll with resistance, support self-efficacy 1

Follow-Up Protocol

Schedule first follow-up within 2-3 weeks after starting pharmacotherapy, then continue at minimum 12-week intervals during treatment and after completion. 1

• Assess for medication adherence, withdrawal symptoms, and psychiatric symptom changes 1
• Reassess depression and anxiety status at every visit, as nicotine withdrawal can exacerbate these conditions 4, 3
• Adjust pharmacotherapy doses as clinically indicated 1
• Progressively intensify behavioral therapy with each treatment line, referring to specialty psychiatric care if depression/anxiety worsens 1

Treatment Duration

Continue initial pharmacotherapy for minimum 12 weeks, with extension to 6 months-1 year to promote continued cessation. 1

• Patients with psychiatric comorbidities may require longer treatment duration 3
• More flexible, open-ended combination approaches show better success in psychiatric populations 3

Common Pitfalls

Do not use pharmacotherapy alone without behavioral counseling—this may be no better than unaided cessation. 1

Do not assume standard cessation programs are adequate for patients with mental health conditions—specialized intervention is required. 1, 3

Do not overlook that smoking cessation can precipitate or unmask depression, even in patients with no prior psychiatric history. 4

Do not fail to prepare patients that nicotine withdrawal symptoms overlap with depression and anxiety symptoms, potentially causing temporary worsening. 4, 3

Do not discontinue psychiatric medications during quit attempts—continue existing antidepressants/anxiolytics for mood stabilization. 5
