When and How to Take It

General considerations for when and how to take Chantix include the following:
  • The medication comes in tablet form. It is taken by mouth twice a day (although for the first three days, it is usually taken just once a day).
  • Chantix is taken for 12 weeks. If you successfully stop smoking, your healthcare provider may recommend an additional 12 weeks of treatment to decrease your chances of starting smoking again.
  • The medication should be taken with a full glass of water after eating.
  • You should set a "quit date" and start taking Chantix one week before this to give the medicine a chance to start working before you try to quit. Alternatively, you can start taking Chantix, then quit sometime between days 8 and 35 of treatment.
  • Chantix should be taken at the same times each day to maintain an even level in your blood.
  • For the medication to work properly, it must be taken as prescribed.

Dosing Information

The dose of Chantix your healthcare provider recommends will vary, depending on a number of factors, including:
  • How you respond to the medication
  • Other medications you may be taking
  • Other medical conditions you may have.
As is always the case, do not adjust your dose unless your healthcare provider specifically instructs you to do so.
