nicotine chewing gum
How does this medication work? What will it do for me?
When a person stops smoking, they go through withdrawal from nicotine that can cause 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 no longer receives through cigarettes. Gradually, the dose is reduced until the person no longer craves nicotine, and they can stop using the medication.
Nicotine gum can also be used during smoke-free periods where smoking is not permitted or desired. You should not smoke and chew nicotine gum at the same time. If you want to quit smoking completely, this medication works best when used with a comprehensive program to quit smoking.
This medication may be available under multiple brand names and/or in several different forms.

How should I use this medication?
When you start to experience a cigarette craving, start chewing one piece of gum. Proper use of the gum is important to receiving the greatest benefit from it. Do not chew the gum as you would ordinary chewing gum. Bite on the gum once or twice and then leave it between your cheek and gum. Repeat after 1 minute. Continue this for 30 minutes, then discard the gum. Repeat this process for every cigarette craving.
It is recommended that you do not drink fluids while chewing the gum since this may affect the ability of the medication to deliver nicotine. The dosage is individualized and depends on how much nicotine is needed to relieve nicotine withdrawal symptoms.
For the first 2 to 4 weeks of treatment, a higher dose (10 to 12 pieces of gum per day) is used, and then the dose is gradually reduced over the next 4 to 12 weeks. When you reach only 1 or 2 pieces per day, then the gum can be stopped. The maximum dose is 20 pieces per day. Most people need a 3 month treatment, although some may need treatment for up to 6 months. You should not use the nicotine gum for more than 6 months without consulting with your doctor.
