Nicotine (replacement therapy) (Nicotine) — Uses, Dosage, Side Effects & Safety

Drug class: Smoking cessation aid (nicotinic receptor agonist)

Overview

Nicotine (replacement therapy) is used to help people stop smoking by reducing withdrawal symptoms and cravings associated with quitting tobacco. It provides a controlled, lower dose of nicotine without the harmful chemicals found in cigarettes. Nicotine replacement therapy (NRT) comes in several forms, including gum, patches, lozenges, inhalers, and nasal sprays. These products deliver nicotine through the skin or mucous membranes, helping to ease the transition away from smoking. Key points: NRT is most effective when combined with behavioral support. It does not contain the tar or carbon monoxide found in cigarettes, making it a safer alternative for those trying to quit. Always follow dosing instructions and consult your healthcare provider for personalized advice.
