Nicotine Replacement Therapy (NRT) is an effective method to help people quit smoking by providing controlled doses of nicotine without the harmful chemicals found in tobacco smoke12. NRT works by replacing some of the nicotine typically obtained from cigarettes, reducing withdrawal symptoms and cravings associated with quitting smoking1.

There are five FDA-approved forms of NRT:

1. Nicotine patches
2. Nicotine gum
3. Nicotine lozenges
4. Nicotine nasal spray
5. Nicotine inhaler

The patches, gum, and lozenges are available over-the-counter, while the nasal spray and inhaler require a prescription2.

How NRT Works

NRT delivers nicotine to the body in a controlled manner, helping to:

• Reduce cravings for cigarettes
• Alleviate withdrawal symptoms
• Allow the user to focus on behavioral changes associated with quitting smoking12

The nicotine patch provides a steady dose of nicotine over 24 hours, while other forms like gum, lozenges, and inhalers offer more immediate relief for sudden cravings5.

Effectiveness

Studies have shown that using NRT can almost double the chances of successfully quitting smoking compared to quitting without assistance2. When combined with behavioral support or counseling, the effectiveness of NRT can be further increased2.

Safety and Side Effects

NRT is generally considered safe for most adults who want to quit smoking5. However, it's not recommended for pregnant women or teens without consulting a healthcare provider2. Some common side effects may include skin irritation from patches, mouth or throat irritation from gum or lozenges, and headaches2.

Using NRT

To maximize the benefits of NRT:

1. Start using NRT as soon as you quit smoking2.
2. Follow the product instructions carefully.
3. Consider combining a long-acting form (like the patch) with a short-acting form (like gum or lozenges) for better craving control26.
4. Use NRT for the recommended duration, typically 8-12 weeks6.
5. Gradually reduce the dosage as directed by your healthcare provider.

Remember, while NRT can help with the physical aspects of nicotine addiction, it's most effective when combined with behavioral support and strategies to address the psychological aspects of smoking cessation25.
