Thrive is the primary ingredient in tobacco products.

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

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

Follow all directions on your medicine label and package. Tell each of your healthcare providers about all your medical conditions, allergies, and all medicines you use.

This medicine is only part of a complete program of treatment that may also include counseling, group support, and behavior changes. Your success will depend on your participation in all aspects of your smoking cessation program.

Use exactly as directed on the label, or as prescribed by your doctor. Start using Thrive gum or lozenges on the same day you stop (quit) smoking or using tobacco products.

Your dose will depend on how many cigarettes you smoked daily before quitting. Read and carefully follow any Instructions for Use provided with your medicine. Ask your doctor or pharmacist if you do not understand these instructions.

After removing the gum or lozenge, wrap it in paper and throw it away in a place where children and pets cannot reach it.

Do not use this medicine for longer than 12 weeks without the advice of your doctor.

Do not use more than one lozenge or piece of gum at a time. Do not use the gum and lozenges together at the same time.

Store at room temperature away from moisture, heat, and light.

Keep both used and unused gum and lozenges out of the reach of children or pets.

Ask a doctor or pharmacist if Thrive is safe to use if you have ever had:

• heart disease, irregular heartbeats;

• a heart attack or stroke;

• if you are on a low salt diet.

Do not use this medicine if you are pregnant unless your doctor has told you to. Use effective birth control, and tell your doctor if you become pregnant during treatment.

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