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.
