The starter pack is the first part of the treatment, containing the first two weeks of tablets (white and light blue). Once you’ve finished this, you’ll move on to a maintenance pack that contains all light blue tablets.
If you’re taking Chantix for the first time, or coming back to using Chantix after not taking it for a while, you’ll always start off on the starter pack. This is to help ‘wean’ you onto the recommended dose slowly.
When you take the starter pack, it’s recommended to have your quit date during the second week, between days 8 and 14.
