Nicotine Lozenges

How it works: 1

  • The over-the-counter lozenge (Commit lozenge) is available in 2 strengths: 2 mg and 4 mg. The 2 mg is recommended for ‘low-dependence’ smokers (do not smoke within 30 minutes of waking up), and the 4 mg is recommended for ‘high-dependence’ smokers (smoke within 30 minutes of waking up)
  • Nicotine lozenges should be dissolved in the mouth rather than chewed and swallowed.

What the evidence says:

  • Strength of Evidence: B The Clinical Practice Guide states that the nicotine lozenge  is, “appropriate as a first-line medication for treating tobacco use” with precautions for pregnant women and individuals with cardiovascular disease (DHHS, 2008, p. 49).
  • Quitting rates
    • Research has found that nicotine lozenges significantly increased quit rates relative to placebo at six weeks and one year among light smokers (<15 cigarettes/day).2
    • Nicotine lozenges have demonstrated effectiveness for those who have a history of past failure with pharmacologic treatment.4
  • Coping with Cravings
    • A recent report demonstrated a nicotine lozenge to be superior to placebo in reducing smoking urge, as well as significantly improved vigilance and psychomotor performances.3
