How to Take CHANTIX

Some important things to know:

  • Always take CHANTIX after eating and with a full glass (8 oz) of water.
  • If you miss a dose, take it as soon as you remember. If it’s close to the time of your next dose, skip the missed dose. Then just take your next dose at your regular time.
  • Make sure that you try to stop smoking on your quit date. If you slip up and smoke, try again.
  • Talk to your doctor or healthcare provider about the potential side effects with CHANTIX, and tell them if you are experiencing side effects that are bothering you or do not go away.

CHANTIX comes as a white tablet (0.5 mg) and a blue tablet (1 mg). You start with the white tablet and then usually go to the blue tablet according to the dosing instructions below.

During the first week of taking CHANTIX, you will slowly increase the dose over 7 days to give it time to build up in your body. After you start taking CHANTIX, you can smoke until your quit date. There are 3 ways to quit with CHANTIX, and your quit date will depend on which way you choose. You should talk to your healthcare provider about which quit approach is best for you.

If you use the Fixed Quit Approach or the Flexible Quit Approach, you will take CHANTIX for 12 weeks (3 months). If you have completely quit smoking by the end of 12 weeks, your healthcare provider may prescribe CHANTIX for another 12 weeks to help you stay smoke-free. Or, if you and your healthcare provider decide that the Gradual Quit Approach is right for you, you will take CHANTIX for a total of 24 weeks.
