Nicotine is the primary ingredient in tobacco products.

Nicotine gum and lozenges are medical products used to aid in smoking cessation in adults. Using a controlled amount of nicotine helps reduce nicotine withdrawal symptoms when you quit smoking.

Nicotine may also be used for purposes not listed in this medication guide.

Do not use this medication if you are pregnant or breast-feeding unless your doctor has told you to.

Ask a doctor or pharmacist before using nicotine gum or lozenges if you have heart disease, a heart rhythm disorder, circulation problems, high blood pressure, history of stroke or heart attack, mouth or dental problems, jaw problems that make chewing difficult, liver or kidney disease, diabetes, thyroid disorder, stomach ulcer, asthma or other breathing disorder, an adrenal gland tumor, or if you are on a low-salt diet.

Do not smoke or use other nicotine products (including snuff, chewing tobacco, nicotine patches, inhaler, or nasal spray) while you are using nicotine gum or lozenges.

Do not use nicotine gum or lozenges for longer than 12 weeks without the advice of your doctor.

Keep both used and unused gum and lozenges out of the reach of children or pets. The amount of nicotine in a used or unused lozenge or piece of gum can be fatal to a child who accidentally sucks or chews on it.

Ask a doctor or pharmacist if it is safe for you to use this medicine if you have:

Nicotine can pass into breast milk and may harm a nursing baby. Do not use this medication if you are breast-feeding unless your doctor has told you to.

Smoking cigarettes during pregnancy can cause low birth weight, miscarriage, or stillbirth. Using a nicotine replacement product during pregnancy or while breast-feeding may be safer than smoking. However, you should try to stop smoking without using a nicotine replacement product if you are pregnant or breast-feeding. Talk with your doctor about the best way for you to stop smoking.

Nicotine lozenges may contain phenylalanine. Tell your doctor if you have phenylketonuria (PKU).
