What is the first line treatment for smoking cessation?

First-Line Treatment for Smoking Cessation

Varenicline (Chantix) 1mg twice daily is the most effective first-line pharmacotherapy for smoking cessation, with combination counseling and behavioral therapy being essential components of successful treatment. 1, 2

Pharmacotherapy Options

First-Line Medications (in order of effectiveness)

1. Varenicline (Chantix)

   • Dosing: Start with 0.5mg once daily on days 1-3, then 0.5mg twice daily on days 4-7, then 1mg twice daily for 12 weeks 3
   • Most effective monotherapy with highest abstinence rates (OR 2.55; 95% CI, 1.99-3.24) 1
   • Can extend treatment for an additional 12 weeks to increase long-term abstinence 3

2. Combination Nicotine Replacement Therapy (NRT)

   • Long-acting NRT (patch) plus short-acting NRT (gum, lozenge, inhaler, or nasal spray)
   • Provides steady background nicotine levels with ability to address acute cravings 2

3. Bupropion SR

   • Dosing: 150mg once daily for 3 days, then 150mg twice daily for 7-12 weeks
   • May help with weight management concerns during cessation 2
   • Can be used alone or in combination with NRT

Behavioral Therapy/Counseling

Behavioral therapy is essential and should be provided alongside pharmacotherapy:

• Minimum recommendation: 4 or more sessions during each 12-week course of pharmacotherapy 1
• Session duration: 10-30+ minutes per session (longer sessions linked to higher success rates) 1
• Even brief counseling (≤3 minutes) increases quit rates significantly 1
• Counseling content should include:
  • Problem-solving skills
  • Coping strategies for nicotine withdrawal
  • Identifying smoking triggers
  • Strategies for high-risk situations 1

Treatment Algorithm

1. Assessment:

   • Assess tobacco use at every visit
   • Evaluate level of nicotine dependence
   • Review previous quit attempts and what worked/didn't work

2. Advise and Set Quit Date:

   • Provide clear, strong advice to quit
   • Set a specific quit date (within 2-4 weeks)

3. Select Pharmacotherapy:

   • First choice: Varenicline 1mg twice daily for 12 weeks
   • Alternative options if varenicline is contraindicated:
     • Combination NRT (patch plus short-acting form)
     • Bupropion SR 150mg twice daily

4. Implement Behavioral Support:

   • Provide in-person counseling or refer to telephone quitline
   • Schedule follow-up within 2 weeks of quit date
   • Address specific barriers and high-risk situations

5. Follow-up and Relapse Prevention:

   • Monitor for withdrawal symptoms and side effects
   • Consider extending pharmacotherapy to 6 months for successful quitters
   • Develop specific relapse prevention strategies

Special Populations

• Pregnant women: Counseling is first-line; if unsuccessful, consider short-acting NRT 1
• Hospitalized patients: Excellent opportunity to begin treatment with counseling and NRT 1
• Patients with COPD/cardiovascular disease: Varenicline has shown effectiveness in these populations 3, 4

Common Pitfalls to Avoid

• Inadequate treatment duration: Minimum 12 weeks of pharmacotherapy recommended
• Using monotherapy only: Combination approaches (medication + counseling) are more effective
• Failing to follow up: Schedule follow-up within 2 weeks of quit date
• Treating all quit attempts the same: Tailor approach based on previous attempts
• Viewing failure as permanent: Tobacco dependence is a chronic condition requiring repeated intervention 2

Remember that smoking cessation significantly reduces morbidity and mortality, and improves quality of life. Multiple quit attempts are often necessary before achieving long-term abstinence, so persistence and continued support are essential.
