Prescription Medication
Varenicline
A prescription medication that reduces both craving and the rewarding effect of nicotine. Among the most effective single medications.
What it is
Varenicline is a prescription medicine (sold under brand names such as Chantix in some markets) that partially stimulates nicotine receptors in the brain.
How it works
It binds to nicotinic receptors, reducing withdrawal symptoms and blocking much of the pleasure from smoking if a person does smoke, which weakens the reward loop.
Evidence
Cochrane reviews and network meta-analyses rank varenicline among the most effective single medications for quitting, roughly doubling or more the odds of success versus placebo in clinical trials.
Evidence strength: Strong
Reported community experiences
Community reports describe reduced enjoyment of cigarettes and reduced craving, alongside reports of nausea, unusual dreams and mood changes. Community records are being compiled in the Experience Database.
Practical considerations
- It requires a prescription: discuss suitability, dosing and side effects with a healthcare professional
- Report any significant mood changes to the prescriber promptly
- Combine with behavioral support for best results
