In days one to three of treatment, most people start with a Chantix dosage of half a milligram, taken once daily. The dosage is then increased to 0.5 mg twice a day during days four through seven. Starting from day eight until the end of the 12-week treatment process, the Chantix dosage is increased to 1 mg twice a day.
Chantix Dosage: An Introduction
The dose of
Chantix™ (
varenicline tartrate) that your healthcare provider recommends will vary, depending on a number of factors, including:
- How you respond to Chantix
- Other medications you may be taking
- Other medical conditions you may have.
As is always the case, do not adjust your Chantix dose unless your healthcare provider specifically instructs you to do so.
Chantix Dosage for Stopping Smoking
Chantix is started at a low dose and then slowly increased in the following manner:
- Days one to three -- Chantix 0.5 mg once daily
- Days four to seven -- Chantix 0.5 mg twice daily
- Day eight to the end of treatment -- Chantix 1 mg twice daily.
You and your healthcare provider will choose a "quit date," which is the day when you will try to stop smoking. Chantix should be started one week before your quit date. Feel free to keep smoking as usual before this date. Even if you have trouble stopping smoking after your quit date, keep taking Chantix and keep trying to quit.
Chantix should be used for 12 weeks. If you have completely stopped smoking by the end of the 12 weeks, your healthcare provider may recommend another 12 weeks to help prevent you from starting again. Continued treatment is not recommended for people who have not successfully stopped smoking within the first 12 weeks.
People with kidney disease (such as kidney failure) may need a lower Chantix dosage, depending on the severity of their disease.
