Chantix is a prescription medication used to help people stop smoking. It is a nicotine-free oral tablet that is available as a brand-only medication.

Chantix prevents nicotine – the addictive chemical contained in cigarettes – from being processed in the brain. By blocking the processing of nicotine in the brain, Chantix reduces the rewarding aspects of cigarette smoking, which reduces the urge to smoke.

When quitting smoking, symptoms of nicotine withdrawal such as restlessness, agitation and depressed mood can be experienced.

This medication must be taken at least 7 days before the desired quit date and is taken with meals and a full glass of water. Talk to your provider to decide on a desired quit date, because this can affect the dosing schedule of this medication.

Chantix is typically taken for 12 weeks, but can be taken for up to 24 weeks if necessary.

Common side effects of this medication are nausea, sleep disturbances, constipation and vomiting.

Additional information

Some patients may experience serious side effects including seizures, enhanced effects of alcohol, skin reactions, new or worsening mental health problems or cardiovascular events. Some people taking Chantix have reported experiencing vivid, unusual dreams during treatment.

This medication should be used with caution in patients with seizures, history of mental health problems, alcohol use, heart or blood vessel problems and those who are pregnant or breast feeding.
