What the Nicotine Lozenge is and How it Works

The nicotine lozenge is a NRT that comes in the form of a small, candy-like tablet. When a nicotine lozenge is placed in the mouth and allowed to dissolve over the course of 20 to 30 minutes, nicotine is absorbed into the bloodstream, relieving short-term cravings to smoke.

Nicotine lozenges are sugar-free and come in cinnamon, fruit and mint flavors.

Because acidic foods and beverages can inhibit the absorption of the nicotine through the lining of the mouth, the manufacturer recommends waiting 15 minutes after eating before using a nicotine lozenge.

Do not smoke while using nicotine lozenges.

Nicotine Lozenge Brands and Strengths

The nicotine lozenge is an over-the-counter medication -- a doctor's prescription is not needed.

Nicotine Lozenge Brand Names:

Brand names associated with the nicotine lozenge are Commit, Nicorette and Nicorette Mini Lozenge. All of these brands are made by GlaxoSmithKline.

Nicotine Lozenge Strengths:

  • The Nicorette/Commit lozenge is available in two strengths, 2mg and 4mg.
  • The Nicorette mini lozenge is also available in 2mg and 4mg strengths, but is smaller in size and dissolves up to 3 times faster than regular Nicorette lozenges.

How Long Do I Use Nicotine Lozenges?

Choose the correct lozenge strength by looking at when your first cigarette of the day is smoked:

  • 4mg nicotine lozenges if first cigarette is smoked within 30 minutes of waking
  • 2mg nicotine lozenges if first cigarette is lit 30 minutes or more after waking

    Nicotine lozenges are used as follows:

    Weeks 1 - 6: Use one lozenge every 1 to 2 hours.

    Weeks 7 - 9: Use one lozenge every 2 - 4 hours.

    Weeks 10 - 12: Use one lozenge every 4 - 8 hours.

    Do not use more than 5 lozenges in 6 hours or 20 lozenges in a 24 hour period. Quit using nicotine lozenges at the end of 12 weeks.

    Consult your doctor if you have trouble stopping.

      Pros and Cons of Nicotine Lozenge Therapy


      Nicotine lozenges offer ex-smokers quick relief from cravings to smoke that are part of nicotine withdrawal.


      Nicotine lozenges are used on an as-needed basis and are similar to candy, both in taste and form. Because of this, the potential to abuse this quit aid is significant.

      Please remember that the nicotine lozenge is a serious medication that must be used exactly as indicated. If you choose to use nicotine lozenges, carefully wean yourself off of them in the amount of time suggested.

      The Bottom Line:

      The nicotine lozenge can help you quit smoking, but keep in mind that it is a quit aid, not a miracle worker. The magic for success with smoking cessation lies within you, not a product.

      Work on developing your resolve to quit smoking one simple day at a time and be patient.

      Time, determination and support will help you win this race. Believe that, believe in yourself, and be willing to do the work it takes to quit for as long as it takes. You'll find that you can quit smoking, just as others have.
