Nicotine gum

Nicotine gum is a type of chewing gum that delivers nicotine to the body. It is used as an aid in nicotine replacement therapy (NRT) to help people stop smoking and tobacco use. The gum is available over the counter in many countries.

History

Nicotine gum was first approved by the Food and Drug Administration (FDA) in 1984. It was initially available by prescription only, but was made available over the counter in 1996.

Use

Nicotine gum is used by mouth as a substitute for tobacco in an effort to stop smoking or using other forms of tobacco. It works by providing a source of nicotine that reduces the withdrawal symptoms experienced when smoking is stopped.

Side effects

Common side effects of nicotine gum include increased heart rate, nausea, and mouth irritation. In rare cases, it can cause more serious side effects such as irregular heartbeat and severe allergic reactions.

Mechanism of action

Nicotine gum works by releasing nicotine, which is absorbed through the lining of the mouth. This helps to reduce the desire to smoke by providing a substitute source of nicotine.
