This medication is used to help people over 18 years of age quit smoking.

When a person stops smoking, they go through withdrawal from nicotine, causing symptoms such as irritability, mood swings, restlessness, trouble concentrating, and increased appetite. This medication helps reduce the symptoms of nicotine withdrawal by replacing some of the nicotine that the person is no longer getting through cigarettes. Gradually, the dose is reduced until the person no longer craves nicotine, and they can stop using the medication. This medication works best when used with a comprehensive program to quit smoking.

Your doctor may have suggested this medication for conditions other than those listed in these drug information articles. As well, some forms of this medication may not be used for all of the conditions discussed here. If you have not discussed this with your doctor or are not sure why you are taking this medication, speak to your doctor. Do not stop taking this medication without consulting your doctor.

Do not give this medication to anyone else, even if they have the same symptoms as you do. It can be harmful for people to take this medication if their doctor has not prescribed it.

Ask your doctor or pharmacist to teach you how to use the nicotine inhaler effectively and to give you tips on quitting smoking. As you inhale or puff through the mouthpiece, the inhaler releases a vapour containing nicotine, which is absorbed through the lining of your mouth and throat. One cartridge contains enough nicotine for about 20 minutes of continuous puffing.

Dispose of used cartridges in a place where children or pets cannot get to them. Store the cartridges at room temperature and protect them from light and humidity.

The dosage is individualized and depends on how much nicotine is needed to relieve nicotine withdrawal symptoms. For the first 3 to 12 weeks of treatment, a higher dose (6 to 12 cartridges per day) is used, and then the dose is gradually reduced over the next 6 to 12 weeks. Once a dose of 1 to 2 cartridges per day is reached, the medication can be stopped. The maximum dose is 12 cartridges per day.

You must stop smoking completely as you begin using the medication. If you are unable to stop smoking by the fourth week of treatment, your doctor will probably advise you to stop using the medication. The medication should not be used at the same time as nicotine gum, patches, or any form of tobacco.
