Are instructions for over-the-counter nicotine replacement therapy products readable?

Area of Science:

• Pharmacology
• Health Communication
• Consumer Product Safety

Background:

• Over-the-counter (OTC) nicotine replacement therapy (NRT) products are widely accessible for smoking cessation.
• Effective use of OTC NRTs relies on clear, understandable instructions.
• Patient comprehension of medication instructions is crucial for treatment efficacy and safety.

Purpose of the Study:

• To evaluate the readability and design characteristics of step-by-step instructions for OTC NRT products.
• To identify potential barriers to consumer understanding in NRT usage guides.

Main Methods:

• A content analysis of the
• How to Use
• sections of all available OTC NRT products (n=6) was conducted.
• Readability was assessed using standard metrics, including reading grade level.
• Text point size, dimensions, and the presence of illustrations were also evaluated.

Main Results:

• The average reading grade level for OTC NRT instructions was 10.5 (±0.8).
• The mean text point size was 9.2 (±1.3), with limited use of illustrations (only 2 products).
• These characteristics suggest a potential mismatch between instruction complexity and general consumer reading abilities.

Conclusions:

• Current readability characteristics of OTC NRT instructions may impede consumer understanding.
• Improvements in text clarity, point size, and visual aids are recommended to enhance NRT product comprehension.
• Addressing these issues can support more effective smoking cessation efforts.
