Chantix (varenicline) is a medication specifically designed to help adults quit smoking. It works by blocking the effects of nicotine in the brain, thereby reducing the urge to smoke. Using Chantix alone is not recommended. It is most effective when used as part of a comprehensive smoking cessation program that provides education, support, and counseling.


  • Set a quit date before starting treatment with Chantix. 
  • Begin taking varenicline as directed by your healthcare provider, 1 to 2 weeks before the quit date.  
  • Take one 0.5-milligram tablet once a day for 3 days.  
  • Increase to one 0.5-milligram tablet twice a day for 4 days. The dose is slowly increased to lessen the chance of side effects (such as nausea, unusual dreams). It is okay to smoke during this time. 
  • Stop smoking on the quit date.   
  • Take the dose prescribed by your healthcare provider twice a day for the rest of the treatment period (usually 12 weeks).   
  • Initiating varenicline treatment before selecting a quit-smoking date is another approach to its utilization. 
  • Start with the 0.5-milligram tablets and increase the dose as directed by your healthcare provider.  
  • Pick a date to quit smoking that is between days 8 and 35 of treatment. Stop smoking on the chosen date.  
  • Take the dose prescribed by your healthcare provider for the rest of the treatment period. 
  • Following your healthcare provider's guidance, commence taking this medication if you're unable to choose a quit date, gradually reducing smoking with the goal of quitting by the end of your treatment. 
  • Follow your healthcare provider’s directions carefully and reduce smoking as directed.  
  • Adhere closely to the instructions on the dosing package if this medication is provided in such a form (starting pack or continuing pack), noting the varying strengths contained within each pack. 
  • Take this medication by mouth after eating food and with a full glass of water.   
  • Take this medication regularly to get the most benefit from it. To help you remember, take it at the same time(s) each day.  
  • Tell your healthcare provider if you continue to smoke after a few weeks of treatment. 
  • Discuss with your healthcare provider if you are unable to quit smoking after 12 weeks of treatment. If successful and cigarette-free after 12 weeks, your healthcare provider may recommend another 12 weeks of treatment with varenicline. 
  • Always consult with your healthcare provider for personalized medical advice and information about the specific dosage and administration of Chantix based on your individual circumstances.   


  • Don't increase the dose of Chantix or take it more frequently than prescribed.
  • The dosage is based on your medical condition and response to treatment.
