Nicotine Replacement Therapy (NRT): A Comprehensive Guide

Nicotine Replacement Therapy (NRT) is a treatment aimed at helping people quit smoking by reducing withdrawal symptoms and cravings for nicotine. NRT provides nicotine without the harmful tar, carbon monoxide, and other chemicals found in tobacco smoke. This guide covers various NRT methods, including nicotine patches, gum, lozenges, inhalers, nasal sprays, and nicotine pouches.

Nicotine Patches as a Nicotine Replacement Therapy Product

Description: Nicotine patches are transdermal patches that release nicotine slowly through the skin and into the bloodstream.

Usage:

• Apply a new patch to a clean, dry, and hairless area of the skin (usually on the upper arm or torso) every 24 hours.
• Rotate application sites to avoid skin irritation.

Dosage:

• Patches come in different strengths (e.g., 21 mg, 14 mg, 7 mg) depending on the smoker’s previous nicotine intake.
• A typical regimen starts with a higher dose and gradually decreases over a period of 8-12 weeks.

Pros:

• Provides a steady, controlled release of nicotine.
• Easy to use and requires minimal effort.

Cons:

• Can cause skin irritation or allergic reactions.
• Less effective for controlling sudden cravings.

Nicotine Gum as a Nicotine Replacement Therapy Product

Description: Nicotine gum is a type of chewing gum that delivers nicotine through the lining of the mouth.

Usage:

• Chew the gum slowly until a tingling sensation is felt, then park it between the cheek and gum.
• Repeat the process for about 30 minutes or until the tingling fades.

Dosage:

• Available in 2 mg and 4 mg strengths.
• The dosage depends on the number of cigarettes smoked daily. For example, heavier smokers may start with the 4 mg gum.
• Typical usage involves chewing one piece every 1-2 hours, gradually reducing the frequency over 12 weeks.

Pros:

• Helps control sudden cravings.
• Oral activity can substitute the hand-to-mouth habit of smoking.

Cons:

• Move the lozenge from one side of the mouth to the other occasionally.

Dosage:

• Available in 2 mg and 4 mg strengths.

Nicotine Inhalers

Description: Nicotine inhalers are devices that deliver nicotine vapor, which is absorbed through the lining of the mouth and throat.

Usage:

• Inhale through the mouthpiece as directed, typically taking frequent, shallow puffs.
• Each cartridge provides a certain number of puffs and lasts about 20 minutes.

Dosage:
