Chantix / Varenicline - Overview
Varenicline, formerly marketed under the brand Chantix, is a prescription medication used as an aid smoking cessation. The brand-name Chantix product has been discontinued in the United States and generic varenicline is the form most commonly prescribed and dispensed. People who want help quitting smoking can connect with a licensed medical provider through Push Health who can prescribe varenicline (including starter packs) when appropriate to do so.
How Does Chantix (Varenicline) Work?
Varenicline tartrate is used as an aid to smoking cessation and belongs to a class of nicotinic receptor partial agonists. The medication binds to α4β2 nicotinic acetylcholine receptors in the brain and reduces the rewarding effects of nicotine and helps ease withdrawal. Blocking nicotine activation of these receptors is thought to reduce the reward experienced upon smoking. It is considered more effective than bupropion (Zyban) or nicotine replacement therapy alone when used with behavioral support.
It is FDA-approved as an aid to smoking cessation. There are anecdotal reports of Chantix medication being used to help people who want to quit using smokeless tobacco products like Zyn but it is are not currently approved by the FDA for that use. For more detailed information, see the varenicline page.
Chantix (Varenicline) - Dosage and Cost
Chantix (varenicline) medication is typically prescribed in standard dosing protocols (subject to the judgment of the medical provider):
- Days 1-3: 0.5 mg once daily
- Days 4-7: 0.5 mg twice daily
- Day 8 onward: 1 mg twice daily
Treatment usually continues for 12 weeks and an additional 12-week course may be offered to those who have successfully quit to help prevent relapse. A flexible "reduce-to-quit" approach is also an option for patients who are not ready to set an immediate quit date. It is recommended that patients take each dose with food and a full glass of water to help reduce nausea.
Generic varenicline is substantially more affordable than the formerly branded Chantix. Many insurance plans and Medicaid programs cover tobacco-cessation medications with little or no cost-sharing. Savings cards and pharmacy coupons can further reduce out-of-pocket cost.

Frequently Asked Questions about Chantix (Varenicline)
How effective is Chantix (varenicline) at helping people quit smoking?
Varenicline is one of the most effective prescription medications for smoking cessation. Clinical trials show continuous abstinence rates roughly double those of placebo. Combining it with behavioral counseling further improves success rates.
Does varenicline cause depression or suicidal thoughts?
The FDA removed the boxed warning for serious neuropsychiatric events in 2016 after the large EAGLES trial. In people without pre-existing psychiatric conditions, the risk was not significantly higher than with nicotine patch or placebo. Patients with psychiatric history should still be monitored as any new or worsening mood changes, agitation, or unusual thoughts should be reported promptly.
When should I set my quit date when starting Chantix?
The usual recommendation is to set a quit date 1–2 weeks after starting the medication (after the titration week). An alternative flexible approach allows gradual reduction with a goal of quitting by week 12.
How long do I need to take Chantix?
The standard course is 12 weeks. Successful quitters may continue for another 12 weeks to reduce relapse risk. Patients who have not quit after 12 weeks should discuss next steps with their provider.
Can I use varenicline and nicotine replacement together?
Combination use is not FDA-approved but has been studied and may offer additional benefit for some highly dependent smokers. A provider can help decide if this approach is appropriate.
Is generic varenicline covered by insurance?
Yes. Most commercial plans and many Medicaid programs cover tobacco-cessation medications under preventive-care requirements. Check your specific plan for formulary details. Generic varenicline is far less expensive than the former brand.
What should I avoid while taking varenicline?
Take with food and water. Use alcohol cautiously - some people report increased sensitivity. Quitting smoking can change the metabolism of other drugs (e.g., warfarin, insulin), so dose adjustments may be needed. Report significant mood changes right away.
