About Chantix™

Chantix is a prescription medicine that helps adults stop smoking. It works best when used as part of a stop-smoking program that helps you change your smoking behavior.

How It Works

Chantix does not contain nicotine, but rather binds to nicotine receptors in your brain and blocks nicotine from activating these receptors. The result is that you do not feel the pleasure from nicotine.


Chantix has not been studied in children under 18 years of age and is therefore not recommended for this age group.

Tell your doctor before starting Chantix if you:

  • Have kidney problems or get kidney dialysis.
  • Are pregnant or plan to become pregnant. Chantix has not been studied in pregnant women. It is not known if Chantix will harm your unborn baby. It is best to stop smoking before you become pregnant.
  • Are breastfeeding. Although it was not studied, Chantix may pass into breast milk.
  • Take any other medicines including prescription and nonprescription medicines, vitamins and herbal supplements. Especially tell your doctor if you take insulin, asthma medicines or blood thinners.

Common Side Effects

Chantix side effects may include:

  • Nausea
  • Sleep disturbance
  • Constipation
  • Gas
  • Vomiting

Dosage Information

How to take Chantix:

  • Set a Quit Date. We recommend you begin working with a Quit Coach to get started. 
  • Start taking Chantix one week before your quit date. This lets Chantix build up in your body. You can keep smoking during this time. Try to quit on your quit date. If you slip, try again.
  • Take Chantix after eating and with a full glass (8 oz) of water.

Recommended dosage:

Chantix comes in 0.5 mg (white tablet) and 1.0 mg (blue tablet). You start with the white tablet and then usually go to the blue tablet.

Day 1 – Day 3
1 white tablet (0.5 mg) each day

Day 4 – Day 7
1 white tablet (0.5 mg) twice a day; morning and evening

Day 8 – End of Treatment (normally 12 weeks)
Blue tablet (1.0 mg) twice a day; morning and evening

Some medications may require dose adjustment after stopping smoking.

Success Rate

In studies comparing Chantix to a placebo (sugar pill), people who took Chantix were about 3.5 times more successful at not smoking after 12 weeks, than persons who took a placebo.
