Nicotine Replacement Therapy — Information Only
Nicotine Lozenge
A dissolvable lozenge that releases nicotine slowly in the mouth, similar to gum but without chewing.
What it is
Nicotine lozenges dissolve slowly in the mouth, releasing nicotine absorbed through the oral lining. They come in different strengths.
How it works
Like gum, the lozenge provides on-demand nicotine to blunt cravings and gives the mouth something to do instead of smoking.
Evidence and effectiveness
Lozenges belong to the NRT evidence base: Cochrane reviews find NRT increases quit rates by roughly 50–60% versus placebo.
Evidence strength: Strong
Guidelines: Recommended by WHO (2024), USPSTF (2021) and NICE NG209 (UK) as an effective form of NRT.
Compared with other options: Similar effectiveness to gum and other single-form NRT. Combining with a nicotine patch is more effective than lozenge alone.
Common adverse effects
Mouth or throat irritation, hiccups, heartburn and nausea are most common. These usually settle as the user learns the correct dissolving technique.
Important safety considerations
Available without prescription; keep out of reach of children — lozenges resemble candy. Same cardiac precautions as other NRT forms. In pregnancy, use only under professional guidance.
Reported community experiences
Community reports describe lozenges as discreet and helpful at work, with some people reporting throat irritation or disliking the taste. Community records are being compiled in the Experience Database.
Common considerations
- Let it dissolve slowly; do not chew or swallow it
- Avoid eating or drinking for 15 minutes around use
- Choose the strength according to product instructions
Limitations
As with all NRT, lozenges relieve nicotine-related symptoms but not the behavioral habit. Follow product labeling and pharmacist guidance.
