The main doses of chantix medication are 0.5mg and 1mg tablets. At the start of the treatment, you need to take the lower dose and then increase it after few weeks. The recommended dose of chantix should be swallowed as a whole with a glass of water. The treatment period with chantix medication extends to about 12 weeks. http://www.chantixhome.com/
