What is the usual dose of Chantix®?

Your doctor will help you decide on the best dosing for you.

  • Usually doses are gradually increased starting one week before the quit date: 
    Day 1 - 3: Once a day x 0.5 mg (if nausea occurs at this stage, you may want to continue this dose for a longer period of time and increase gradually as the nausea subsides) 
    Day 4 - 14: 0.5 mg, twice a day 
    Day 15 - Week 12: 1.0 mg, twice a day 
  • Another treatment regimen is to begin Chantix dosing, and then quit smoking between Days 8 and 35 of treatment.

Some persons can remain at the Day 4 - 14 dose (0.5 mg twice a day) and do well; both dose levels have been shown to be effective.
