Overview

Chantix is a drug prescribed by physicians as a part of a patient's smoking cessation plan. As with any prescription drug, some side effects are common and Chantix is not recommended for everyone.
How Chantix Works

Chantix (generic name, varenicline) works in the brain by blocking nicotine receptors and reduces the urge to continue smoking.

Severe Side Effects

Severe side effects include impaired ability to drive or operate heavy machinery. Suicidal thoughts or behavior are another severe side effect.
Success with Chantix

Chantix should be used along with behavior modification and counseling to aid in smoking cessation.
Chantix Duration of Use

The recommended course of treatment is 12 weeks. Some patients will be prescribed an additional 12 weeks of treatment.
Discuss with a Doctor

If you are prone to kidney problems or mental illness discuss this with your doctor before starting Chantix.
