Chantix is used as a smoking cessation medicine or treatment. It is used together with behavior modification and counseling support to help you stop smoking cigarettes. Chantix works in the brain to block the pleasurable effects of smoking. This helps to decrease your desire to keep smoking.

Before using Chantix, tell your doctor if you have kidney disease, or a history of mental illness.

Use Chantix exactly as it was prescribed for you. Do not use it in larger amounts or for longer than recommended by your doctor. Follow the directions on your prescription label. See also Chantix Warnings.
