Nicotine nasal spray and inhalation are medical products used to help you stop smoking and help reduce nicotine withdrawal symptoms as you quit smoking.

Nicotine nasal or inhalation 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.

Follow all directions on your prescription label and read all medication guides or instruction sheets. Your doctor may occasionally change your dose. Use the medicine exactly as directed. Tell your doctor if you feel an increased urge to use more of this medicine.

Read and carefully follow any Instructions for Use provided with your medicine. Ask your doctor or pharmacist if you do not understand these instructions.

Do not use the nasal spray more than 5 times per hour or 40 times in 24 hours. Do not use more than 16 nicotine inhaler cartridges per day.

The amount of nicotine in a used or unused bottle or cartridge can cause serious harm to a child who accidentally sucks or chews on it. Seek emergency medical attention if this happens.
