When you smoke a cigarette, nicotine enters your body through your lungs and travels to your brain. Nicotine replacement therapy ( NRT) works by substituting the source of nicotine to “replace” the nicotine you inhale when you smoke. For people who are quitting smoking, NRTs can help by delivering a safer alternative source of nicotine than cigarettes. They also can reduce or eliminate the symptoms of withdrawal, making it easier for some people to quit. NRTs have been extensively tested and used by millions of people, and considered safe and effective ways of quitting smoking. To optimize your chances of success, medications should be a consideration in your quit day checklist. Note: The content in this section is for informational purposes. Not all nicotine replacement therapies are right for everyone. Be sure to discuss the option of nicotine replacement therapy with your doctor or healthcare provider. Types of NRTs There are many different types of NRTs that are available either over-the-counter or from a prescription from your doctor. They vary in the dose of nicotine they supply and the way in which the nicotine is delivered into the body. As with any medication, talk to your doctor. Not all medications are safe for women who are pregnant and breastfeeding, or for people who may be taking other medications. Types of NRTs include: Nicotine gum – Nicotine gum is an over-the-counter product that you can buy at your local pharmacy. A piece of nicotine gum is chewed briefly, allowed to rest in the mouth, then chewed again. This process enables nicotine to be absorbed into the body through the mouth lining. Nicotine gum is used for two to three months, up to a maximum of six months. Nicotine lozenges – Nicotine lozenges come in the form of hard candy and release nicotine into the system as they dissolve in the mouth. Each lozenge lasts for about a half hour and can be.
Examples Nicotine gum and lozenges release nicotine slowly into the mouth. Nicotine patches stick to your skin and slowly release nicotine through the skin into your bloodstream. The nicotine inhaler has a holder that contains nicotine. The inhaler delivers a puff of nicotine vapor into your mouth and throat. You can buy nicotine gum, patches, and lozenges without a prescription. You do need a prescription to buy nicotine inhalers. Note: Nonprescription nicotine replacement therapy products cannot be sold legally to people younger than age 18. A doctor may prescribe one of these products if a person younger than 18 is dependent on nicotine. How It Works Nicotine replacement therapy ( NRT) helps reduce nicotine withdrawal and craving by supplying your body with nicotine. It contains about one-third to one-half the amount of nicotine found in most cigarettes. People become dependent on the nicotine in cigarettes because it increases the levels of certain chemicals, such as dopamine and norepinephrine, in their brains. When people quit smoking, the levels of those chemicals drop. Their bodies react by having nicotine withdrawal symptoms such as grouchiness and hunger. Nicotine from medicines increases the levels of dopamine and norepinephrine just like nicotine from cigarettes does. Chemical levels in the brain are kept level so that withdrawal symptoms are reduced. This can temporarily replace the nicotine that a person got from smoking cigarettes. Nicotine replacement can be used in smaller and smaller amounts until a person no longer needs it. When you inhale tobacco smoke, the nicotine in the smoke moves quickly from your lungs into your bloodstream. The nicotine in replacement products takes much longer to get into your system. This is why nicotine replacement medicines are much less likely to cause dependence on nicotine than are cigarettes and other tobacco.
