Nicotine Gum

Topic Overview

You chew nicotine gum as a way to help yourself quit using tobacco. The gum contains nicotine and feels and looks like chewing gum. When you chew the gum, the nicotine begins to slowly release into your mouth. Then you hold the gum in your mouth between your cheek and gums.

Cigarette smoke passes nicotine almost instantly into the blood through the lining of the lungs, and the blood takes it to the brain in a few seconds. The nicotine in the gum takes several minutes to reach the brain. This makes the "hit" less rapid with the gum than with a cigarette. Nicotine gum also delivers much less nicotine to your body than a cigarette would.

How to use nicotine gum

Nicotine gum comes in several flavours and in two strengths: 2 mg and 4 mg. Start with the 4 mg strength if you smoke 25 or more cigarettes a day or if your healthcare provider recommends it.

Do not chew nicotine gum like normal gum. Instead, use the "chew and park" method:

  • Use one piece of gum at a time.
  • Put a piece of gum into your mouth, and chew it slowly a few times to break it down. Chewing will release a "peppery" taste. Next, park the gum between your gums and cheek, and leave it there.
  • Repeat the process of chewing and parking for about 15 to 30 minutes, or until there is no more peppery taste released by chewing. The gum is used up at that point. The nicotine from the gum makes its way into your system through the blood vessels that line your mouth.
  • If you chew the gum without parking it, the nicotine will be released directly into the saliva in your mouth and you will swallow it. This may cause a stomach ache, hiccups, or heartburn. Also, it may take longer for the nicotine to get into your bloodstream.

Other tips for using nicotine gum

  • Avoid drinking beverages, especially acidic ones (such as coffee, juices, and soda pop), for 15 minutes before and after you chew. Your body may not absorb the nicotine well because of the acid in these drinks.
  • Follow the written instructions that come with the gum for how many pieces you can use per day. Most people use 10 to 15 pieces a day. (Do not chew more than 30 pieces of the 2 mg gum or 20 pieces of the 4 mg gum a day.)
  • Consider using the other materials provided with the nicotine gum. These can help you change your smoking behaviour.
  • Avoid the common mistakes of chewing too little gum or stopping use too early. Using too little of the gum will result in withdrawal symptoms similar to those caused by abruptly stopping smoking.
  • As the urge to smoke decreases, use fewer pieces of gum each day. When you are using only 1 or 2 pieces a day, stop using the gum completely. However, you may want to keep some nicotine gum with you in case you find yourself in a potential relapse situation.

It is possible to become dependent on nicotine gum, but this is rare.

Nicotine gum does have side effects. Read the package insert before you use this medicine.

What should I watch for?

You may be getting too much nicotine if you have:

  • a fast heartbeat
  • nausea and vomiting
  • dizziness or weakness
  • fainting
  • sweating
  • blurry vision or trouble hearing
  • confusion
  • seizures

If you have any of these after taking nicotine gum stop using it and see a doctor right away.

Side effects may include:

  • sore mouth
  • jaw ache
  • hiccups
  • stomachache

This may be because the gum wasn’t used in the right way. Please review how to use the gum.

Stop using this gum and see a doctor right away if you have an allergic reaction.

Allergic reaction symptoms may include:

  • very bad itching
  • hives
  • swelling in your mouth
  • a tight feeling in your chest
  • trouble breathing

Talk to your pharmacist about how quitting might affect other medicine you take. Your body may respond to some medicine differently once you stop using tobacco.

Some people have had suicidal thoughts when they try to quit smoking without medicines. Sometimes quitting smoking can lead to some mental health problems you already have, like depression, getting worse.

Before taking any quit-smoking treatment, tell your healthcare provider (doctor, pharmacist, or nurse):

  • if you’ve ever had depression or other mental health problems
  • about any symptoms or concerns you had other times you tried to quit smoking, with or without medicines
