Is there a correlation between the use of Nicorette (nicotine) lozenges and orange/yellow tongue discoloration in a patient who denies any pain, burning, or irritation?

From the Guidelines

There is a correlation between Nicorette (nicotine) lozenges and orange/yellow tongue discoloration, which is a known cosmetic side effect of nicotine lozenges that is temporary and harmless. This discoloration occurs because nicotine lozenges contain food dyes and flavorings that can temporarily stain the tongue, particularly when used regularly 1. The absence of pain, burning, or irritation in the patient is consistent with this being a benign side effect rather than a concerning medical condition. The staining typically resolves on its own with good oral hygiene practices, including regular brushing of the tongue and teeth, and adequate hydration. Some key points to consider:

• Nicotine replacement therapy comes in various forms, including lozenges, which can help with smoking cessation efforts 1.
• The effectiveness of nicotine replacement therapy can be enhanced when combined with behavior therapy, as seen in studies where the addition of behavior therapy to NRT increased the odds of success nearly 3-fold 1.
• If a patient is concerned about the appearance, they can try switching to a different nicotine replacement therapy such as patches or gum, though these alternatives may have their own side effects. The discoloration does not indicate any reduction in the effectiveness of the nicotine replacement therapy and should not be a reason to discontinue use if the lozenges are helping with smoking cessation efforts.

Stop use and ask a doctor if mouth, teeth, or jaw problems occur The FDA drug label does not answer the question.

From the Research

Correlation between Nicorette Lozenges and Tongue Discoloration

• There is no direct evidence in the provided studies to suggest a correlation between the use of Nicorette lozenges and orange/yellow tongue discoloration 2, 3, 4, 5, 6.
• The studies primarily focus on the efficacy of nicotine replacement therapy, including lozenges, for smoking cessation and the factors influencing their use, such as nicotine dependence and withdrawal symptoms 3, 5, 6.
• None of the studies mention tongue discoloration as a side effect of nicotine lozenge use or explore the relationship between nicotine consumption and tongue color changes.

Nicotine Lozenge Use and Side Effects

• The studies do report side effects associated with nicotine lozenge use, such as nausea 3, but do not mention tongue discoloration.
• One study found that fast metabolizers of nicotine may need to use more lozenges to achieve the same clinical response as slower metabolizers 5, but this does not relate to tongue discoloration.

Conclusion on Available Evidence

• Based on the provided studies, there is no evidence to suggest a correlation between Nicorette lozenge use and orange/yellow tongue discoloration.
• Further research would be needed to investigate this specific correlation, as the current evidence does not address this question.
