How does this medication work? What will it do for me?
This medication belongs to a family of medications known as nicotine replacement therapies. It is used to help people over 18 years of age quit smoking. When a person stops smoking, they go through withdrawal from nicotine that causes 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.
The nicotine patch when applied to the skin delivers a steady dose of nicotine over a 24-hour period. 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.
What form(s) does this medication come in?

How should I use this medication?
Ask your doctor or pharmacist to teach you how to use the nicotine patch effectively and to give you tips on quitting smoking. Only one nicotine patch should be applied once a day to an area on the upper body or upper outer arm that is non-hairy, intact, non-irritated, clean, and dry.
After 24 hours, the old patch should be removed and discarded and a new patch applied. Be sure that new and discarded patches are kept out of the reach of children. It is very important to apply the patch to a new site on the body and avoid any unnecessary contact with the medicated part of the patch. If during handling you do come into contact with the medicated portion of the patch, quickly wash the affected area with water only. Do not use soap as it can increase the amount of nicotine absorbed into the body. Avoid contact with your eyes.
Your initial dose and duration of therapy can depend on a number of factors such as weight, number of cigarettes you smoke, and various medical conditions. Speak with your doctor or pharmacist before beginning a nicotine patch therapy.
Therapy for most people begins with the 21 mg/day patch and continues for 6 weeks. It is important to reassess your initial dose of nicotine after the first 2 weeks of therapy. The next stage of therapy will gradually reduce the dose of nicotine. After successful completion of the first 6-week stage, the 14 mg/day patch should be started for 2 weeks, immediately followed by the 7 mg/day patch for another 2 weeks. Treatment will generally take 8 to 12 weeks. You should not use this medication for more than 3 months. You must stop smoking completely when taking this medication.
Many things can affect the dose of medication that a person needs, such as body weight, other medical conditions, and other medications. If your doctor has recommended a dose different from the ones listed here, do not change the way that you are taking the medication without consulting your doctor.
It is important to use this medication on a regular schedule as prescribed by the doctor. If you miss a dose of this medication, take your next scheduled dose.
