⚡ Quick Answer — Champix — varenicline 1 mg for smoking cessation<\/h3>\n

Champix is varenicline 1 mg, an α4β2 nicotinic-acetylcholine partial agonist that reduces nicotine cravings and the rewarding effect of smoking. Set a quit date 8–14 days into a 12-week course; titrate from 0.5 mg once daily up to 1 mg twice daily. Most effective when combined with behavioural support; the 2016 EAGLES trial removed the historical neuropsychiatric black-box.<\/p>\n<\/div>\n

What is Champix?<\/h2>\n

Champix is a smoking-cessation aid containing varenicline 1 mg<\/strong> (film-coated tablets), supplied by Pfizer. It is a selective partial agonist at the α4β2 subtype of the neuronal nicotinic acetylcholine receptor — the same receptor nicotine binds — and is one of the most effective monotherapies for tobacco dependence, with cessation rates roughly two to three times those of placebo and consistently superior to single-agent nicotine-replacement therapy in head-to-head trials.<\/p>\n

How varenicline works<\/h2>\n

Varenicline binds the α4β2 nicotinic receptor with both agonist and antagonist<\/strong> properties: as a partial agonist it produces about 30–60% of nicotine’s dopamine release, dampening cravings and withdrawal; as an antagonist it occupies the receptor and blocks the dopaminergic surge from any cigarette smoked while on therapy, so a cigarette during the course feels much less rewarding than usual. This dual action distinguishes it from bupropion (an atypical antidepressant with weak nicotinic antagonism) and from nicotine-replacement therapy (full agonism only).<\/p>\n

How Champix is used<\/h2>\n

The standard adult course is 12 s\u0103pt\u0103m\u00e2ni<\/strong>. Set a quit date 8–14 days into the course — do not stop smoking on day 1. An alternative “flexible quit” approach lets the smoker reduce gradually over the first 12 weeks and quit any time before the end.<\/p>\n\n\n\n\n\n\n\n\n

Optional 12-week extension<\/td>\n1 mg twice daily<\/td>\nFor those who quit successfully — doubles 1-year abstinence rates<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

Take with a full glass of water after a meal<\/strong> — nausea is the most common reason for discontinuation and is reduced by food and adequate hydration. If 1 mg twice daily is not tolerated, dropping back to 0.5 mg twice daily is acceptable and still active.<\/p>\n

Neuropsychiatric history.<\/strong> The original FDA black-box warning (2009) was removed in 2016<\/strong> after the EAGLES trial (8,144 randomised smokers, including a stable-psychiatric cohort) found no statistically significant excess of clinically significant neuropsychiatric events versus placebo, NRT, or bupropion. However, smoking cessation itself can unmask underlying mood symptoms; patients with serious mental illness should still be monitored for new or worsening depression, anxiety, agitation, or suicidal ideation, especially in the first 4 weeks. Stop and contact a clinician if these emerge.<\/div>\n
