Chemical name: Varenicline

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.

Average costs for Chantix with Medicare drug coverage1

Your copay and deductible costs for any prescription drug can vary depending on what coverage stage you’re in.

Deductible stage Typical copay stage
Your deductible is the amount of money you must spend on covered drugs before your Medicare drug coverage starts paying its share of costs.

In the deductible stage, you’re responsible for the full cost of your prescription drugs.

Some Medicare prescription drug plans have a $0 deductible. Medicare drug plans cannot have a deductible more than $480 in 2022.
After you meet your Part D deductible, you enter the initial coverage period.

During this phase (the typical copay stage), you pay a copayment (flat fee) or coinsurance (percentage) for your covered medications.
$42 – $538 $25 – $538

Additional information

Quitting smoking can lower the chances of lung and heart disease as well as certain cancers.

Chantix has been proven to be significantly better at helping people quit smoking than standard nicotine replacement methods such as a nicotine patch. The dose of Chantix will be gradually increased to minimize treatment-related nausea and insomnia.

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.
