Deciding About Using Medicines To Quit Smoking

How can you decide about using medicines to quit smoking?

What are the medicines you can use?

Your doctor may prescribe varenicline (Champix) or bupropion (Zyban) to help you cope with cravings for tobacco. These medicines are pills that don't contain nicotine.

You also can use nicotine replacement products. These do contain nicotine. There are many types.

  • Gum and lozenges slowly release nicotine into your mouth.
  • Patches stick to your skin. They slowly release nicotine into your bloodstream.
  • An inhaler has a holder that contains nicotine. You breathe in a puff of nicotine vapour through your mouth and throat.
  • Mouth spray releases a mist that contains nicotine.

What are key points about this decision?

  • Using medicines can double your chances of quitting smoking. They can ease craving and withdrawal symptoms.
  • Getting counselling, along with using medicine, can raise your chances of quitting even more.
  • If you smoke fewer than 5 cigarettes a day, you may not need medicines to help you quit smoking.
  • These medicines have less nicotine than cigarettes. And by itself, nicotine is not nearly as harmful as smoking. The tars, carbon monoxide, and other toxic chemicals in tobacco cause the harmful effects.
  • The side effects of nicotine replacement products depend on the type of product. For example, a patch can make your skin red and itchy. Medicines in pill form can make you sick to your stomach. Or they can cause nausea, dry mouth, and trouble sleeping. For most people, the side effects are not bad enough to make them stop using the products.
  • Warnings. Health Canada warns that people who take bupropion or varenicline and who have any serious or unusual changes in mood or behaviour or who feel like hurting themselves or someone else should stop taking the medicine and call a doctor right away. If you already have a mood or behaviour problem, be sure to tell your doctor before you decide to use these medicines.
