How It Works
Nicotine replacement therapy (NRT) helps
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 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 products.
replacement therapy is safe when used properly. Nicotine by itself is not
nearly as harmful as smoking. Tars, carbon monoxide, and other toxic chemicals
in tobacco cause harmful effects, not the nicotine.

been shown to be safe in most people with heart disease. But if you recently
had a or if you have serious heart problems, such as an irregular
or rapid heartbeat (arrhythmia) or chest pain (angina),
consult your doctor before you use nicotine replacement products.
Doctors do not often recommend nicotine replacement
therapy for people younger than 18, largely because the products have been
tested only on adults. The side effects of nicotine replacement therapy for
young people are not well known. If a teen smokes daily and has had withdrawal when trying to quit, sometimes a doctor will prescribe nicotine products.

Your chances of quitting are best when you combine
nicotine replacement therapy with a complete smoking cessation program that
includes setting a quit date, having a plan in place for dealing with
smoking triggers, and getting support from a doctor,
counselor, or support group.
Since all NRTs appear to work equally
well, many smokers choose a treatment based on how easy it is to use and what
possible side effects it may cause. All forms of nicotine replacement have side
effects, but the types of side effects differ across NRTs. Very few people
(less than 5%) have to stop using a nicotine replacement product because of
Stopping nicotine replacement therapy abruptly may
cause some of the same withdrawal symptoms that occur when you stop smoking
cigarettes. You are less likely to have withdrawal symptoms if you gradually
decrease the dose or number of uses of the specific therapy each day.
It is possible for a person to become dependent on a nicotine replacement
product, although this is rare.

- A skin rash at the location of the patch.
This may be a reaction either to the sticky backing on the patch or to the
nicotine. People with sensitive skin or allergies to adhesive should not use
the patch. Moving the patch to a different part of your body or using a
nonprescription antihistamine cream, ointment, or gel (such as Benadryl) may
relieve some of the discomfort.
- Sleep problems when using a
24-hour patch, such as having trouble sleeping or having especially vivid
dreams. This is because your brain isn't used to getting nicotine when you are
sleeping. Removing the patch a few hours before you go to sleep may help reduce this side effect.
If the sleep problem is a nicotine withdrawal symptom, not a side effect,
removing the patch may not help. Talk with your doctor if you have sleep

What To Think About
If you slip or smoke a little, don't give up. Talk to someone who has quit smoking or to a counselor, to get ideas for what to do.

Symptoms of too much nicotine are

(such as coffee, juices, and soda pop) for 15 minutes before and after you use
these products. Your body may not absorb the nicotine well because of the acid
in these drinks.
Choosing a form of nicotine replacement therapy is usually a matter of personal choice. If you smoke more than 20 cigarettes a day, or you smoke within 30 minutes of waking up in the morning, use the highest dose of a product, whether it is gum, lozenges, the patch, or a combination of NRT.
The U.S. Food and Drug Administration (FDA) says it's okay to start using a nicotine replacement
product on your quit date, even if you aren't able to stop smoking right away.
If you find you cannot continue to use one form of
nicotine replacement because of its side effects, stop using that form and try
